INTRODUCtioN
The family Calyceraceae includes 54 small herbs or
subwoody plants species, annuals or perennials, endemic to
southern South America (southern Brazil, Bolivia, Paraguay,
Uruguay, Chile and Argentina; Chiapella 1999a, 1999b,
Zanotti & Pozner 2008). Most species grow in arid Andean
or Patagonian habitats; a few species inhabit eastern, more
humid environments, and only one grows in Malvinas
(Falkland) Islands (Chiapella 1999a, 1999b; Zanotti &
Pozner 2008). Six genera have been distinguished within
Calyceraceae: Acicarpha Juss. (5 species from Argentina,
Bolivia, Brasil, Perú and Uruguay); Boopis Juss. (13 species
from Argentina and Chile); Calycera Cav. (14 species from
Argentina, Bolivia and Chile); Gamocarpha DC. (6 species
from Argentina and Chile); Moschopsis Phil. (7 species
from Argentina and Chile) and Nastanthus Phil. (9 species
158
from Argentina and Chile). About 90% of the species grow
along the Andes of Argentina and Chile (Zanotti & Pozner
2008). The most complete information on systematics and
taxonomy of Calyceraceae was published by Pontiroli
(1963), Chiapella (1999a, 1999b), Galvão Magenta &
Pirani (2002), Hellwig (2007), Zanotti & Pozner (2008),
and literature therein.
Calyceraceae morphology deserves an exhaustive
reevaluation. Some contributions have been published
during the last 20 years, and these new data confirm a major
problem with this family: the lack of sharp boundaries
among genera. Reitz (1988) was one of the first authors
to suggest the synonymy among Boopis, Gamocarpha and
Nastanthus due to poor morphological differences. The
palynological results published by Hansen (1992) showed
at least two main pollen morphologies in the family, which
were not uniform within genera. According to Carlquist
& DeVore (1998) the diversity of wood anatomy in
The genus Nastanthus: Zavala-Gallo, L. et al.
Calyceraceae (14 species from 5 genera sampled) suggests
adaptations to particular ecological conditions, with little
phylogenetic information. Characters of fruit morphology
are used to delimit Calyceraceae genera. However, Zanotti
& Pozner (in prep.) did not find enough morphological or
anatomical evidence to distinguish Boopis from Nastanthus,
in agreement with Hellwig (2007), who suggested the
synonymy among Nastanthus, Boopis and Moschopsis.
Finally, a preliminar molecular phylogeny of the family
(Pozner et al. in prep.), suggests that Calycera, Nastanthus
and Boopis are not monophyletic.
Because of that poor generic delimitation, some species
(particularly those of Nastanthus) are difficult to identify,
even with the most comprehensive keys (Pontirolli 1963;
Chiapella 1999a), and consequently the identification
of herbarium collections is not reliable. In addition, the
most recent nomenclatural synopsis of Calyceraceae for
southern South America (Zanotti & Pozner 2008) revealed
names that need revision, particularly those combined or
synonymyzed under Nastanthus. For these reasons, and
toward a complete and comprehensive taxonomic revision
of Calyceraceae, we present here the nomenclatural revision
of 51 names published, combined or synonymyzed under
Nastanthus. We recognized six species, established correct
names, new synomyms, lectotypes, updated distribution,
and included morphological observations. We do not
attempt to present any hypothesis about evolutionary
relationships or monophyletic groups, rather just to
delimitate species and clear up the nomenclature, which
is useful whether Nastanthus later remains as a segregate
genus or is merged with another genus, or if a species
accepted here is transferred to another genus.
Materials and MethoDS
Collections of Calyceraceae housed at BAB, CORD,
CTES, LIL, MERL, SGO, SI were studied (Holmgren et
al. 1990). Type material from BAB, CORD, E, GH, K,
LP, P, RNG, SGO, S, SI, W, or their digital images, and
original descriptions were also consulted. Drawings of the
new species were based on rehydrated herbarium material.
Illustrations of Nastanthus patagonicus, N. falklandicus
and N. scapigerus were taken from Chiapella (1999a) and
reproduced with the editor’s authorization.
Taxonomic treatment
Nastanthus Miers, Ann. Mag. Nat. Hist. ser. 3, 6(33): 184.
1860 [Sep 1860].Type species: Nasthanthus agglomeratus
Miers (= Nastanthus ventosus (Meyen) Miers).
Perennial, rosulate herbs with napiform, contractile root,
and a central, usually unbranched stem (only N. falklandicus
D.M. Moore might have a rizomatous habit). Leaves more or
less fleshy, oblong-oblanceolate to spatulate, glabrous, base
attenuate, apex obtuse, blade entire, lobate to pinnatifid,
margin entire to dentate. Flowers in head-like pedunculate
inflorescences. Peduncles scapiform, fleshy, terete or
compressed, smooth or sulcate, solid at anthesis and probably
fistulose at fruit maturity, simple or branched, sometimes
densely aggregated or coalescent even into a compound
terminal inflorescence. Involucre with a patelliform basal
tube (absent or very reduced in N. falklandicus), with 512 uniseriate lobes, oblong, obtuse, sinuate to trilobate.
Receptacle large, fleshy, accrescent during fruit ripening.
Palea linear-espatulate, or absent. Flowers numerous. Calyx
with suborbicular sepals, with open, valvate or imbricate
aestivation, accrescent with the fruit. Corolla funnel-shaped
or cyllindrical, usually with a differentiated cup-shaped
limb, lobes triangular to oblong, uncinate, with valvate
aestivation. Staminal tube inserted in the corolla tube, with
5 oblong nectarial glands, and distally ending in 5 very short
filaments. Anthers connate, base sagittate. Style exserted,
terete, distally thicker. Stigma globose papillose. Ovary
cylindrical, 5-sulcate. Achene prismatic, ridged, corky,
crowned by the sepals that surround a terminal apiculum
more or less evident. Seed oblong.
According to Miers (1860-1869), Nastanthus forms
fertile, short-tubulose flowers and sterile long-tubulose
flowers in the same inflorescence. We did not find that flower
dimorphism, but a continuous variation in the corolla tube
length among flowers in the same inflorescence, being all
of them apparently fertile. However, field observations (L.
Zavala-Gallo) revealed two types of long-tubulose flowers
morphologically alike: one type secondarily exposes pollen
on the stigma, while the other type does not, suggesting
male sterility. Therefore, Nastanthus does have flower
dimorphism, but its relationship with sex expression needs
a more detailed anatomical analysis.
Nastanthus includes species endemic to Chile and
Argentina (Chiapella 1999b, Zanotti & Pozner 2008), which
grow along the Andes from the 25º S towards the south,
and all over Patagonia, including Tierra del Fuego and
Malvinas (Falkland) Islands. This area corresponds to the
phytogeographic Andea-Patagonean Dominion (Altoandine,
“del Desierto”, Chilean and Patagonean Provinces) and the
Subantarctic Dominion (Subantartic and Insular Provinces)
(Cabrera & Willink 1980) (Fig. 1). Although some species
of Nastanthus may grow in woody habitats, most of them
prefer arid, steppe-like habitats, frequently related to high
altitudes, and probably also to streams or ponds due to the
presumable hydrocoric dispersal of their fruits (Hellwig
2007).

Etymology. The specific epithet refers to the aggregated
disposition of inflorescences, occurring in densely caespitose
masses.
This species is denoted by the nectarial glands being
located just below the free filaments, at the distal end of
the staminal tube, by few flowers per inflorescence, and by
depressed fruits. Flowers have a green corolla tube and a
white limb.
The specimen SGO-043609 is chosen as lectotype
since is the only one whose label is clearly correlated. On
SGO-057221 the type material was assembled along with
other specimens, so that we can not distinguish which label
corresponds to each specimen.

Etymology. The specific epithet refers to the inflorescences
that grow in a confluent mass, strongly aggregated.
This is the only species of Nastanthus with an accrescent
corolla persistent on the fruit (in the remaining species the
corolla may persist, but it is non-accrescent and withered)
and without inflorescence paleas. The corolla is tubulose and
white, but during fruit ripening the tube turns green towards
the apex, and the limb turns reddish, while most of the
corolla tube remains white, and swells by the development
of a spongy tissue, similar to that of the fruit ridges.

The analysis of original material reveals that Boopis diazi
is based on an specimen that should have been assigned to
N. compactus. This specimen possesses all distinct attributes
of the species (spatulate-pinnatifid blades, short peduncles,
flowers with reddish calyx teeth, long and cylindrical corolla
tube, and an accrescent corolla persistent on the fruit).
Gamocarpha pumila is a nomenclatural synonym of
Boopis compacta because the type material of the former
housed at K is an isotype of the latter. This conclusion
is based on the finding that both types are fragments of
a single plant. Moreover, labels on both sheets specify
the same collector and date (Ph. Germain, 1856-1857),
but differ in location. The holotype in SGO indicates
“Cordillera de Linares” and the type in K “Cordiliéres de
Maule (sede orient)”; nevertheless, from 1826 to 1873,
Linares was part of the administrative subdivision of
Maule province.

The genus Nastanthus: Zavala-Gallo, L. et al.
Perennial, glabrous herb; stem about 2-7 cm tall and 0.5-1.8
cm in diam., fleshy, solid, wider towards the apex, ending
into a compound inflorescence, narrowing to the base into a
more or less horizontal structure (rhizome?). Leaves densely
imbricate, 1.2-4 cm long x 0.2-0.4 cm wide, narrowly
oblong to oblanceolate or subspatulate, base attenuate into a
petiole; blade entire, fleshier than the petiole, with a median
longitudinal groove, apex acute to rounded. Inflorescence
terminal, compound, made of basal pedunculate heads that
becomes sessile and coalescent towards the apex of the stem;
basal peduncles usually simple, 2 cm long, one-headed, with
a basal foliar bract, which becomes closer to the involucre in
the upper heads. Involucre with 3 narrowly triangular bracts,
0.2-0.3 x 0.3-0.4 cm, basally connate. Receptacle 0.4-0.8 cm
in diam. Palea 6-10 per head, narrowly elliptic to oblanceolate,
0.05 x 0.15-0.3 cm. Flowers white. Sepals obtuse to rounded,
0.5 x 0.5 mm. Corolla cylindric, 3 mm long, tube 2 mm long,
lobes acute triangular, cucullate, 0.8 mm long. Staminal tube
inserted in the basal half of the corolla tube, with 5 nectarial
glands, and free, distal, short filaments. Anthers 0.6 mm
long. Style exserted, about 1 mm long. Immature achenes
prismatic, 2.5 mm long, with 5 longitudinal ridges crowned
by the sepals. Mature achenes unknown.
Distribution. It is endemic to the Malvinas (Falkland)
Islands, apparently restricted to the southwestern coast
of the Gran Malvina/West Falkland Island (Moore 1967;
Fig. 1).
Etymology. The specific epithet refers to the geographic site
where this species is circumscripted (Malvinas (Falkland)
Islands).
Species only known by the type collection and one paratype
collected in 1839, Robinson s.n. (K) (Moore 1967). As we
could not study the type material, the description was based
on the original publication of Moore (1967). According to
this author, N. falklandicus is protogynous, a very improbable
feature considering the mechanism of secondary pollen
presentation typical of Calyceraceae (Erbar & Leins 1995).
This species is distinguishable by its habit, with narrowly
oblong to oblanceolate or subspatulate leaves densely
arranged along the stem, and compound inflorescences.
Flowers are white and smell strongly of nectar.
Perennial rosulate herbs about 2-25 cm tall and 6-20 cm
in diam., with a short stem. Leaves thick, spatulate, 2-7
cm long, base attenuate into a petiole of 1.3-4 x 0.15-0.5
cm; blade 0.8-3 x 0.8-3 cm, lobed, margin dentate, lobes
obtuse to triangular, mucronate. Peduncles cylindrical, 2-20
x 0.1-0.5 cm, with a central, larger peduncle of 15 x 3 cm
in old specimens. Involucre with 5-7 lobes, 0.5-1 x 0.350.8 cm, variable in shape: triangular mucronate at apex;
triangular, minutely dentate, with apex and teeth mucronate;
or spatulate lobate with apex and lobules mucronate.
Receptacle convex, 1-6 cm in diam., accrescent during fruit
ripening. Palea thick, spatulate to rectangular, apex obtuse
mucronate, 0.35 x 0.1 cm in receptacles with flowers to 1
x 0.7 cm in receptacles with fruits. Flowers whitish-green,
20-500 per inflorescence, up to 1,000 in the central, larger
head. Calyx with open or imbricate aestivation; sepals small,
suborbicular, emarginate, translucent, 0.3-0.4 x 0.5-0.7 mm.
Corolla infundibuliform, tube 2.5-3 mm long x 0.8-1.2 mm
wide, limb 1.6-1.8 x 0.9 mm, lobes triangular, uncinate, 1.41.8 x 0.8-0.9 mm, with valvate aestivation. Staminal tube 3
mm, inserted on the upper third of the corolla tube, with 5
oblong, indistinct, nectarial glands, 0.6 x 0.2 mm, of median
position, and apical free filaments 0.2-0.4 mm. Anthers 1
mm long. Style exserted, 5 mm (staminate phase) to 6 mm
long (pistillate phase). Ovary cylindrical, 1.4-2 x 0.8-1 mm.
Achenes prismatic, wrinkled, 2.4-2.7 x 1-1.6 mm, with 5
longitudinal, thin, narrow, laminar ridges, crowned by an
apiculum 0.25-0.35 mm long, with reduced or accrescent
lanceolate sepals (1 x 1 mm). Seed 2 x 0.7 mm.
Distribution. Endemic to southern Argentina, from north
Neuquén to Santa Cruz (Fig. 1), occurring both in the steppe
and the Andean forests.
Etymology. The specific epithet refers to the geographic
region where this species exclusively grows.

This species is distinguishable by the largest inflorescences
within the genus, with a central head of 1-6 cm diam., which
may sustain ca. 1,000 flowers; paleas are also large. Flowers
are greenish-white with long corolla limbs.
According to Chiapella (1999a), young individuals of N.
patagonicus can be misidentified as N. scapigerus due to the
overall similarity of the leaves, flower colour, inflorescences
and habit. The absence of a central, larger peduncle and
inflorescences of similar size in young individuals of N.
patagonicus increase the similarity between both species.
However, both entities can be still discerned by the
morphology of fruit ridges and sepals, and flower size.

There are three specimens of the original material from
Claudio Gay collection with labels of Herb. Mus. Paris; one
of them is housed at P and the other two are conserved at
K. The P specimen is selected as lectotype since vegetative
and reproductive structures are well preserved and it better
matches Rémy’s description. One of the specimens at K also
matches the original description but it consists in a single
and fragmentary plant. The other sheet at K includes poorly
preserved fragments of a plant that do not match with Rémy
protologue of Boopis scapigera. This material was originally
identified as “Boopis scapigera Remy”, it shows the pencil
inscription “non” on the name, and, at the margin of the
sheet, an incomplete inscription where “Nastan…” can be
read. These inscriptions appear in all specimens revised by
Miers for his Contributions to Botany (1860-1869). This
specimen from K is part of the material used by Miers to
typify Nastanthus pinnatifidus (= Nastanthus ventosus); its
references agree with the protologue and it has been relocated
on the same sheet with the syntype Cuming 325.
The name Nastanthus spathulatus is one of the better
known among Chilean and Argentinean botanists and it is
based on Boopis spathulata. Nevertheless, all characters of
the B. spathulata types found at SI and W clearly match
the type material of Boopis scapigera; the only difference
is that B. spathulata holotype is a specimen bearing flowers
and broad blades, whereas the B. scapigera lectotype (P)
bears fruits. Miers (1860-1869) noted the similarity between
both species but he drew no conclusion because he had not
seen the Philippi holotype. However, these similarities are
evident in the illustration of N. scapigerus in Miers (18601869). The specimen at SI is chosen as lectotype since is the
best conserved and has the Philippi´s label.
Miers (1860-1869) established the new species
Nastanthus laciniatus based on three specimens from
different collectors. Later, Reiche (1900) treated this taxon as
a variety of N. agglomeratus. The analyses of their syntypes
revealed that they correspond to N. scapigerus, because of
their corolla limb completely cleft. Considering the three
syntypes available in K, Cuming 326, from “Cordillera de
Chile”, is the best preserved, retaining the plant form with
many inflorescences and achenes, and perfectly matches
Miers’ description. The remainder syntypes, Gillies s.n. from
“Los Palomares” and Bridges s.n. from “Ojos de Agua”,
conserve more vegetative structures (leaves and roots), but
fewer reproductive ones, that are required to identify the
species and were especially used by Miers.
Some of the synonymies here listed were cited in
synonymy before: Boopis dubia and Boopis reichei
under Nastanthus spathulatus; and Boopis miersii under
Nastanthus scapigerus (Reiche 1900, Zanotti & Pozner
2008). All of them represent morphological forms related
with distinct environmental pressures that exist in the
Andean-Patagonian distribution of the species, including
longitudinal, latitudinal and altitudinal ranges.
The genus Nastanthus: Zavala-Gallo, L. et al.
Boopis araucana, only known from type material, is a
specimen with longer, more branched and leafy peduncles
than the typical condition in N. scapigerus, but an exhaustive
study on inflorescences form, flowers and leaves, show that
both taxa are conspecific. The specimen SGO-057225 is
chosen as lectotype since it possesses more reproductive
material than SGO-043594.
Due to the existence of many forms within N. scapigerus
and the lack of characters to distinguish between both
taxa we consider Boopis bellidifolia as a synonym of N.
scapigerus.
Nastanthus chubutensis was created based on two
specimens from the Andean limit of Chubut province
of Argentina. Its characters match the Boopis scapigera
description of Remy and also its general aspect resembles
the lectotype of B. scapigera since all possess fruits.
Probably, these similarities were noted before by Hicken
(1919), who considered Nastanthus chubutensis as a variety
of N. bellidifolius.
The comparison between N. scapigerus and related taxa,
treated here as synonyms, shows that vegetative morphological
characters are scarcely variable, and the reproductive ones
(floral characters) remain constant (Table I).
The illustration published by Chiapella (1999a: 514, Fig.
397) of N. scapigerus corresponds to N. patagonicus.

Distribution. Andes of Chile and Argentina, between 27º37ºS, also occurring near the Pacific coast in Chile and in

Etymology. The specific epithet, ventosus, is a Latin term
which has many meanings, all of them related to the wind
and its attributes. In this case, it may refer to the kind of
environment in which the species occurs (ventosus=
windy), or the wide morphological variability which
characterizes this species (ventosus= fickle, changeable). It
may also denote the intensely aggregated arrangement of
inflorescences (ventosus= puffed up).
Plants usually produce many scapiform peduncles
aggregated into a hemispherical, caespitose mass (Pontiroli
1963), resembling the general shape of a cauliflower
(Reiche 1900). Condensed or lax forms may be observed
under different environmental conditions along its Andean
distribution. The nectarial glands are more evident during
the staminate phase. Flowers are green in the corolla tube
and white at the limb.
Miers (1860-1869) considered Calycera ventosa Meyen
under Nastanthus and established the combination Nastanthus
ventosus (Meyen) Miers. Nevertheless, Calycera ventosa
was usually considered as a synonym of Boopis scapigera
J.Remy since Weddell (1857), and later as Nastanthus
scapigerus (J.Remy) Miers by Reiche (1900, 1901), Hicken
(1919), Chiapella (1999a) and Zanotti & Pozner (2008).
The study of the type material of both Calycera ventosa
and Boopis scapigera provides the separation of the former
species by its smaller sepals, pinnatifid leaves, and many
condensed inflorescences (see also Remy, 1847[1848]). In
addition, the analyses of numerous herbarium specimens
corresponding to Nastanthus agglomeratus and the type
material of Calycera ventosa revealed that they share mostly
the same characters on reproductive structures, and that
Calycera ventosa can be placed within the morphological
variation considered for N. agglomeratus, differing only
by its longer and less condensed peduncles. Therefore, we
consider both taxa as conspecific, and the earliest correct
name is Nastanthus ventosus (Meyen) Miers.
The holotype of Calycera ventosa Meyen, presumably
housed at B, and the complete Meyen collection, were
destroyed. All herbaria where Meyen specimens could be
conserved (BR, CAS, CGE, K, L and P; Stafleu & Cowan,
171
Gayana Bot. 67(2), 2010
1988) were consulted but no isotype of Calycera ventosa
was found. Meyen (1834) did not cite paratypes either.
Therefore, Weddell’s illustration is chosen as lectotype
since evidence suggests it was based on Meyen’s original
material: “The drawings (probably based in part on sketches
by Weddell) are by Alfred Riocreux …” (Stafleu & Cowan,
1988, vol. 7, p. 140), and Reiche (1900: 1031) stated:
“La figura de Weddell se estableció sobre una muestra
original”.
The specimen Gillies s.n. from BM is considered
as the holotype of N. agglomeratus, since it has Miers’
original labels. It is worth mentioning that isotypes of N.
agglomeratus (Gillies s.n.), N. laciniatus (Cuming 326)
and N. pinnatifidus (Cuming 325) are mounted on the same
herbarium sheet at E, but labels have been mismatched to
specimens. This becomes evident when comparing isotypes
from E, types from K and BM, illustrations and protologues
(Miers, 1860-1869). We concluded that the specimen of N.
laciniatus is associated with Cuming 325 (E-00259116)
label (see synonymy of N. scapigerus below), the specimen
of N. pinnatifidus with Gillies s.n. (E-00259115) label (see
synonymy of N. ventosus above) and the specimen of N.
agglomeratus with Cuming 326 (E-00259114) label (see
synonymy of N. ventosus above). Furthermore, mistakes
have been repeated in another two sheets from E, where a
specimen of N. pinnatifidus is labeled as Cuming 326 (E00259117), and a specimen of N. laciniatus is labeled as
Cuming 325 (E-00259118).
Nastanthus agglomeratus var. pinnatifidus is not
considered here as a good variety because the foliar
morphology of N. ventosus includes characters used to
define the variety. The specimen Cuming 325 is chosen
as lectotype since it better describes the plant morphology
and it is better conserved than the syntype Gay s.n. from
“Cordillera de Coquimbo”; the later is fragmented and
poorly preserved.
The remaining varieties of N. agglomeratus (N.
agglomeratus var. gayanus, N. agglomeratus var. gilliesii
and N. agglomeratus var. breviflorus) were previously
considered as synonyms of N. agglomeratus by Zanotti
& Pozner (2008). About Boopis breviflora, the specimen
SGO-043591 is chosen as lectotype since it has better
conserved material and greater number of flowers and fruits
than SGO-057222.
The holotype of Boopis oocaulis is probably housed at
NY (Zanoni 1982, O’Leary 2006). The isotype possesses
short blades, consisting of five small lobules, few-flowered
inflorescences of 20-30 flowers, flowers with a short corolla
tube with abbreviated whitish lobules, closely matching
N. ventosus. Differences with N. ventosus (more flowers
per inflorescence and leaves with more than 5 lobules)
may be caused by environmental conditions such as soil
development and water availability. Besides, B. oocaulis
is known only from the type material, and other authors
172
(Pontiroli 1963) have pointed out the doubtful validity of
this taxon.
The type specimen of Boopis sanjuanina can be
placed confidently within the morphological variation of
Nastanthus ventosus; even Hieronymus (1881) remarked
about his uncertainty when creating the species. Moreover,
Pontiroli (1963) confused N. agglomeratus with N.
caespitosus and erroneously cited Boopis sanjuanina in
synonymy to the later species.
The comparison between N. ventosus and related
taxa, here treated as synonyms, shows that vegetative
morphological characters vary, whereas the reproductive
ones (floral characters) remain constant (Table II).

We have only seen a digital image of the holotype, and
the specimen is so depauperate, poorly preserved and folded
that its morphology can hardly be evaluated. Although
some features resemble N. ventosus, the decision about its
synonymy is postponed until an examination of the type
material can be made.

The genus Nastanthus: Zavala-Gallo, L. et al.
Conclusions
Based on our results, Nastanthus includes six species: N.
caespitosus, N. compactus, N. falklandicus, N. patagonicus,
N. scapigerus, and N. ventosus. Five species and three variety
names, up to date in use, are newly placed into synonymy (N.
agglomeratus, N. spathulatus, N. chubutensis, N. araucanus,
N. diazi, N. agglomeratus var. pinnatifidus, N. agglomeratus
var. laciniatus, and N. spathulatus var. bellidifolius).
