The genus Cistanche Hofmmg. & Link. has seven species in Iran of which one taxon is endemic to area of “Flora
Iranica”. During reconsidering of Orobanchaceae for the Farsi version of Flora of Iran we found a new subspecies
of Cistanche which is described as C. flava (C. A. Mey.) Korsh. subsp. bicolor Saeidi & Shahi. Moreover, C.
eremodoxa Bornm., previously reported from Khorassan province, is proposed as a synonym of C. ambigua (Bunge)
G. Beck. A diagnostic key to all species of Cistanche distributed in Iran is also provided. For each species, ecology
and some taxonomic remarks are presented.

Introduction
Cistanche with about 18 species is distributed in the
arid and semi-arid regions of the world (Blatter 1921;
Agrawal 1984; Musselman 1984). In Iran, this genus
contains seven species including: C. ambigua (Bunge)
Beck, C. fissa (C. A. Mey.) Beck, C. flava (C. A. Mey.)
Korsh., C. laxiflora Aitch. & Hemsl., C. ridgewayana
Aitch. & Hemsl., C. salsa (C. A. Mey.) Beck and C.
tubulosa (Schrenk) Wight. Cistanche comprises
holoparasite and perennial herbs, with alternative
leaves and flowers arranged in spike or racemes. Its
corolla is subactinomorphic and calyx lobes are
rounded at the margin. The chromosome number 2n=40
has been recorded for Cistanche by Schneeweiss et al.
(2004). Recently molecular phylogenetical studies of
some species of Cistanche including C. tubulosa and C.
salsa have revealed that they were not closely related to
each other (Moriya et al., 1995; Tomari et al., 2002;
Tomari et al., 2003). There is no detailed taxonomic
study on Cistanche in Iran except for that presented in
Flora Iranica (Rechinger, 1964), which lacks taxonomic
description of the species, but encompasses a
diagnostic key and notes on the distribution of the
species.
Gilli (1976) who considered 6 species of this genus
in Iran also presented notes on geographical
distribution of the species and an identification key to
them.
The present paper contributes to the ongoing
taxonomic revision of Cistanche in Iran.
A short Latin diagnosis, description of the new
subspecies of Cistanche flava and its differences with
the typical subspecies are presented.
Material and methods
This work is mainly based on the study of herbarium
materials deposited in main Iranian herbaria, i.e.,

FUHM, IRAN, TARI, TUH and author’s own
collection from wild populations which are deposited in
the herbarium of Guilan University (GUH). In addition,
the studied species were compared with type specimens
and authentic materials in the herbaria: K, B, LE and
Gazi University in Ankara. Characters were selected
from color and density of hairs on the stem and leaf;
length bracts and presence of pubescence, presence or
absence of bractlets, length of bractlets and their
pubescence; number, shape, size and pubescence of the
calyx lobes; color of flowers and anthers; capsule shape
and the number of its valves. Selected localities
representing the distribution of seven species of
Cistanche distributed in Iran are given in the appendix.
Results and Discussion
The main result of this paper is recognizing a new
subspecies of C. flava. The new subspecies is easily
distinguishable from the typical subspecies by the color of
corolla, absence of hairs on lobes of calyx and the apex of
anthers. The comparison of the material of the new
subspecies with the type specimen in LE (Azerbaijan,
between Baku and Salijanami, 1947.11.7, Novopokrosky
899) also confirmed that the differences are considerable
enough to represent a new taxon. The differences between
two subspecies are shown in Table 1.

Notes on the ecology, distribution and affinities of
Cistanche in Iran.
Cistanche tubulosa is a highly polymorphic species
which is adapted to different ecological conditions such
as dry habitats, sea coasts and sand dunes with
sufficient water supply and prefers clay, gypsum and
salty soils. For various reasons, this species has a wide
distribution and many hosts in Iran. It is the most
frequent species of Cistanche in Iran and in the world.
Cistanche tubulosa is closest to C. flava by having
flower color, calyx shape and some other characters
similar to that, but there are distinct differences
between them. The bracts of C. tubulosa are oblate or
ovate-lanceolate, while the bracts of C. flava are oblate
or lanceolate-linear. Also the bractlets in C. tubulosa
are smaller than the calyx, whereas they are as long as
calyx or longer than the calyx in C. flava. Cistanche
flava has a restricted distribution in center of Iran.
Cistanche laxiflora is adapted to different ecological
conditions. This species lives on non-saline conditions,
it also thrives under saline soil and is widely distributed
through the central region of Iran. Its type specimen is
collected from Harirud river in Afghanistan. This
species is very similar to C. tubulosa, but C. laxiflora
has lax inflorescence, while C. tubulosa has dense
inflorescence. Furthermore, C. laxiflora differs from C.
tubulosa in length and width of inflorescence and its
proportion to plant height. This species is endemic to
the area of Flora Iranica (Rechinger1964).
Cistanche salsa is adapted to sandy and salty soils
and coast of salty rivers. It is a halophyte plant and
Anabasis is known as its only host. This species differs
from C. ambigua in corolla color, presence or absence
of woolly-hairs on the dorsal surface of bract and its
size.
The species C. ambigua and C. eremodoxa were
recorded as separate species in the Flora Iranica, but the
occurrence of C. ambigua was considered as doubtful
in Iran (Rechinger 1964). These species are said to
differ in presence or absence of hairs at the margin of
corolla lobes. Cistanche eremodoxa was reported by
Bornmüller (1936) from Khorassan province in Iran;
while Gilli (1976) and Schischkin (2000) considered it
as a synonym of C. ambigua. Based on the examined
herbarium specimens and observation of the type
specimen in Berlin (B), it is reasonable to propose C.
eremodoxa as a synonym of C. ambigua. A list of host
plants of different species of Cistanche in Iran is given
in Table 2.
