Albrecht-von-Haller-Institut für Pflanzenwissenschaften Abteilung für Systematische Botanik Karspüle 2, D-37073, Göttingen, GERMANY ABSTRACT We document 137 species of pteridophytes new to the flora of Peru since the publication of the previous flora by Tryon and Stolze, in 1994. Some of these are recently described species (but no new species are described herein), while many are range extensions of known species from adjacent countries; a few are species that have been elevated in status from lesser rank, or species that have a new name, not mentioned by Tryon and Stolze. Most of these additions are the result of new collections, unknown at the time of the previous flora, and most are from montane rain forests and cloud forests, on the eastern slope of the Andes, from Dept. Amazonas to Dept. Cuzco. This area is known to be the richest for ferns, in Peru. These additions bring the known total of pteridophyte species for Peru to about 1200, making it one of the richest countries in the world for ferns and lycophytes. RESUMEN Se registra 137 especies de pteridofitas nuevas para la flora del Perú desde la publicación previa en 1994 del trabajo de Tryon y Stolze. Algunas son especies recientemente descritas, mientras que la mayoría son registros de extensión de distribución desde paises vecinos y unas pocas han sido elevadas en categoría desde rangos menores o tienen un nombre nuevo no mencionado por Tryon y Stolze. La mayoría de estas adiciones son el resultado de recolectas nuevas, desconocidas entonces para la flora previa. Estas adiciones incrementan a cerca de 1200 el total de especies conocidas para el Perú, haciendo de éste uno de los paises más ricos en el mundo en helechos y licofitas. INTRODUCTION It is almost an axiom in floristic work, especially in the tropics, that a flora is outdated by the time it is published. Ten years following the completion of the six-fascicle publication of the “Pteridophyta of Peru,” by Tryon and Stolze (1989a, 1989b, 1991, 1992, 1993, 1994), approximately 137 additional species of ferns and SIDA 21(4): 2321 – 2342. 2005 2322 BRIT.ORG/SIDA 21(4) allies have been added to the flora. Thirty-five of these have been recently described in other publications, while the majority (80 spp.) are range extensions of species known previously only from adjacent countries; still others are species that were synonymized (we believe inappropriately; 19 spp.) or now go under a name not mentioned by Tryon and Stolze (2 spp.), or were treated at lesser (varietal) rank (1 sp.). Most of these species additions are the result of new collections, unknown at the time of completion and publication of the Tryon and Stolze flora. These additions, and two corrections (species erroneously reported from Peru), bring the previous (Tryon & Stolze 1994) total of 1060 up to 1195 species. The number will continue to grow, as new species are described and as taxonomic revisions of especially difficult and poorly studied groups (e.g., Elaphoglossum) are completed. As a conservative estimate, there may be as many as 100 species already collected but still undescribed, so that the total number of pteridophytes from Peru is likely to eventually approach, if not exceed, 1300 species. In Peru, the most species-rich areas for ferns appear to be along the eastern slope of the Andes, in montane rain forests and cloud forests (León & Young 1996; Young 1992; Young & León 1999). Tryon and Stolze (1994) reported more than 390 pteridophyte species for each department in this zone, from Amazonas to Cuzco, and our new records increase these numbers further (Table 1). The four departments for which we report more than twenty new species are either in this zone (Amazonas, San Martín, and Pasco) or in lowland Amazonia (Loreto). Proportionally, the increase in the number of known species is highest in Loreto (12%) and Amazonas (11%). In both departments, intensive collecting has recently taken place in preparation for a local florula (in Amazonas, by Rodolfo Vásquez/Henk van der Werff) or in connection with ecological studies (in Loreto, by Hanna Tuomisto). A further indication of the incomplete, but improving knowledge of Peruvian ferns derives from recent collections by Henk van der Werff. In a 2004 shipment of ca. 255 sheets collected from Peru, all from Pasco, Prov. Oxapampa, about 40 species were first records for Dept. Pasco (of which ca. seven were new for Peru), and another four were putatively undescribed (no doubt more, but monographic study is needed). Numbers like this suggest that, ultimately, all of the departments on the eastern slope of the Andes will be found to contain ca. 500–600 species of pteridophytes. Obviously, southwestern Peruvian departments containing substantial dry areas (Arequipa, for instance) will always have low numbers of ferns, regardless how much collecting is done. For fern diversity, it is usually true that wetter is better, especially in the mountains; habitat diversity, both climatic and edaphic, can substantially add to this diversity. We are reluctant to extrapolate or generalize from the pteridophyte data to other groups of plants or animals, because different taxonomic groups may vary in general biogeographic patterns, ecological requirements, and the state of SMITH ET AL., NEW RECORDS OF PTERIDOPHYTES FROM PERU 2323 TABLE 1. Number of pteridophyte species in the different departments of Peru. The numbers of known spp. are taken from Tryon and Stolze (1994); the numbers of new spp. are from the present paper or publications cited in this paper. Many additional departmental records are known for species previously reported from Peru by Tryon and Stolze (1989a, 1989b, 1991, 1992, 1993, 1994), but these are not the subject of this paper (Smith, unpubl. data).

However, we expect that many groups of organisms will converge on the pattern that the highest numbers of new species records will be found from areas with wet climate, high habitat heterogeneity, and low exploration-density, especially the remote areas of the eastern Andes and western Amazonia. Our ignorance of the Peruvian fern flora can be seen in statistics for Elaphoglossum. Mickel (in Tryon & Stolze 1991) recognized 124 species of Elaphoglossum (including Peltapteris); of these, 50 were newly described in the flora or in papers immediately preceding the flora. However, Elaphoglossum can not necessarily be taken as representative for the ferns, inasmuch as it is one of the largest (and consequently most complex and understudied) genera in the Andes. Recent estimates for the number of pteridophyte species in tropical and subtropical Latin American countries include 1008 species for Mexico (Mickel 2324 BRIT.ORG/SIDA 21(4) & Smith 2004), 1358 species for Mesoamerica (Davidse et al. 1995), and 1204 species for Venezuela (Smith 2005a). The lack of reliable estimates for Colombia, Ecuador, Bolivia, or Brazil make meaningful comparisons of diversity and species richness with those countries impossible, but we predict that all four will be found to contain in excess of 1200 species of pteridophytes, and the total may well approach 1500 species in Colombia. The goal of this paper is to put on record, in a single place, as many as possible of the recent species additions to Peru, similar to the efforts for flowering plants done by Ulloa et al. (2004). We generally do not address in this paper differences in taxonomic opinion from the previous Tryon/Stolze treatment, except when those differences result in recognition of additional taxa at species rank. As an example of the kind of information not included in this paper, there is now evidence suggesting that Notholaena nivea (Poir.) Desv. (Tryon & Stolze 1989b) be placed in Argyrochosma (as A. nivea (Poir.) Windham) (Windham 1987). In fact, many of the infraspecific taxa treated by Tryon and Stolze (e.g., the three varieties of Notholaena nivea) have been or will be accorded species rank in floristic treatments of other neotropical countries (e.g., for Mexico, Mesoamerica, Venezuelan Guayana, Ecuador, and Bolivia; Mickel & Smith 2004; Davidse et al. 1995; Smith in Steyermark et al. 1995; Jørgensen & León-Yánez 1999; Kessler & Smith, in prep.). Other examples illustrating these differing opinions might include Asplenium radicans L. var. cirrhatum (Rich. ex Willd.) Rosenst. and A. radicans var. partitum (Klotzsch) Hieron., both of which many authors (Adams in Davidse et al. 1995; Mickel & Smith 2004) elevate to species rank (as Asplenium cirrhatum Rich ex Willd. and A. flabellulatum Kunze, respectively). These matters are largely a matter of taxonomic opinion, and the overall number of taxa recognized will not change. However, comparisons of taxon numbers at a given rank between countries need to take into account such subjective disagreements. In this paper, we publish no new taxa or combinations, these are better left to monographers or those doing more detailed floristic work, and require the examination of types and perhaps further field and herbarium studies, both within and outside Peru. Ongoing floristic projects in adjacent areas, especially Bolivia (by Kessler and Smith) and Ecuador (by Øllgaard and collaborators), as well as the production of local florulas within Peru (Río Cenepa area, Dept. Amazonas, by Vásquez et al., in prep.; Cordillera de Yanachaga in Dept. Pasco) can be expected to shed light on many additional taxonomic problems and result in additional species descriptions. Many of the species accepted and treated by Tryon and Stolze now are known from one or more additional departments within Peru. We do not mention these in the list below, or in Table 1, but specimens can be found in various herbaria, especially the Missouri Botanical Garden (MO) and the herbarium of the University of California, Berkeley (UC), as well as herbaria in Peru (CUZ, SMITH ET AL., NEW RECORDS OF PTERIDOPHYTES FROM PERU 2325 HAO, HUT, USM). Some of these additions can also be found in the TROPICOS database: http://mobot.mobot.org/W3T/Search/vast.html The following species are additions to the Peruvian flora since the completion of the Peruvian pteridophyte flora by Tryon and Stolze (1994). None of these species were recognized at species rank by Tryon and Stolze, and most of the names were not mentioned at any rank. A few names (e.g., Adiantum villosissimum Mett. ex Kuhn) were discussed as problematic species or possible synonyms of highly variable recognized species, or treated as synonyms. Further work on the Peruvian fern flora must await description of undescribed species, preferably in a monographic context or at least considering closely related species. An updated fern flora of the country is needed but probably attainable only in the distant future. Adiantum argutum Splitg. (Pteridaceae) PERU. Madre de Dios. Prov.

We believe that this variety is a good species and that the correct name at species rank is Diplazium balliviani Rosenst., type from Bolivia. The true D. grandifolium, type from SMITH ET AL., NEW RECORDS OF PTERIDOPHYTES FROM PERU 2331 the West Indies, does indeed occur in Peru, but apparently no specimens were seen by Tryon and Stolze. We note that the two Peruvian specimens of D. grandifolium cited are from 1900 and 2300 m, while 16 of 18 specimens seen of D. balliviani from the southern Andes are from low elevation, 100– 400 m; two others, both from Bolivia, extend to 1100 m. Diplazium immensum Stolze (Athyriaceae) PERU. San Martín: Knapp & Alcorn 7749 (F, MO, neither seen).

Perhaps most of the specimens cited by Tryon and Stolze (1989a:59) as H. apiculatum Mett. ex Kuhn from Peru are better referred to H. dendritis, a low-elevation, smaller species (fronds mostly 3–5 cm long) with ovate, rather than obovate involucres, included, shorter receptacles (generally < 1 mm long vs. often slightly exserted receptacles ca. 2 mm long in H. apiculatum), and smaller sporangia (ca. 0.3 mm long vs. 0.5 mm long).

La Libertad, as well as other specimens seen from Dept. Lima and Dept. Lambayeque from low elevations are this species, and not P. lasiopus Klotzsch, as cited Tryon and Stolze (1993:130). Polypodium gilliesii differs from P. lasiopus, where it was synonymized by both Hensen (1990) and Tryon and Stolze (1993), by having abaxially glabrous or nearly glabrous blades (lacking long, septate hairs) and generally longer, narrower, somewhat diverging, and darker rhizome scales (most prominently seen in Venezuelan specimens, the type locality); in addition, P. lasiopus grows at elevations above 1700 m in Peru, while P. gillliesii is recorded from 400–800(–1300) m, primarily on lomas.

Cited by Tryon and Stolze (1993) as a synonym of P. sessilifolium Desv., which we believe is not closely related. Polypodium kunzeanum has much less regular venation, sometimes with two included and themselves anastomosing veins within an areole, cordate-based, nonadnate pinnae (the basalmost with lobes overlapping the rachis), and non-clathrate rhizome scales.

Cajamarca, Huánuco, Madre de Dios, and Pasco that may be this species. Tectaria pubens R.C. Moran (Dryopteridaceae) PERU. Loreto: Prov. Maynas: ca. 50 km downriver from Iquitos, Explorama Lodge, ca. 120 m, Moran 3647 (HOLOTYPE: MO; ISOTYPE: UC); additional collections from the same general locality cited by Moran (1992:138).

(MO not seen, UC); San José de Lourdes, 5°00'S, 78°54'W, 1800 m, Vásquez 26157, et al. (MO not seen, UC). Subsumed under Grammitis asplenifolia (L.) Proctor by Tryon and Stolze (1993:104), but easily distinguished; some (probably most) of the specimens cited by them as G. asplenifolia are, in fact, Terpsichore chrysleri, specifically van der Werff 8608 (UC) and Woytkowski 35485 (UC), but Terpsichore asplenifolia (L.) A.R. Sm. s. str. also occurs in Peru. Terpsichore mollissima (Fée) A.R. Sm. (Grammitidaceae) PERU. Pasco: Prov.

Cuzco: near San Lorenzo, 2300–2500 m, León & Young 4487 (HOLOTYPE: USM; ISOTYPE: UC) (León & Smith 2003:84). Thelypteris cinerea (Sodiro) A.R. Sm. (Thelypteridaceae) PERU. Amazonas: road Chachapoyas–Mendoza, a little past Molinopampa, 6°14'11"S, 77°35'49"W, 2400 m, van der Werff 15095, et al. (MO not seen, UC). Thelypteris steyermarkii A.R. Sm. (Thelypteridaceae) PERU. Cuzco: Prov. Paucartambo: Kosñipata Valley, Km 150, San Pedro, Río Unión and Río Kosñipata junction, 1800 m, in sandy beach-river, Núñez 11958 (MO). Trichomanes accedens Hook. (Hymenophyllaceae) PERU. Amazonas: Quebrado El Almendro, 5°14'40"S, 78°21'24"W, 430 m, van der Werff 14560, et al. (MO not seen, UC). Loreto: Prov. Requena: 140 m, van der Werff 10112, et al.

Discussed and considered probably synonymous with T. cristatum Kaulf. by Tryon and Stolze (1989a:98). Trichomanes dactylites Sodiro (Hymenophyllaceae) PERU. Cajamarca: Prov. San Ignacio: San José de Lourdes, laderas del Cerro Picorana, 4°58'00"S, 78°53'01"W, 2500–2540 m, Campos 5933, et al. (MO not seen, UC). 2340 BRIT.ORG/SIDA 21(4) Trichomanes pilosum Raddi (Hymenophyllaceae) PERU. Amazonas: Prov. Bagua: Dist. Imaza, Quebrada Almendra, 5°14'40"S, 78°21'34"W, 400 m, van der Werff 16124, et al. (MO not seen, UC). Trichomanes spruceanum Hook. (Hymenophyllaceae) PERU. Loreto: Prov. Maynas: Dist. Iquitos, Puerto Almendras, 130 m, on white sand, van der Werff 9845, et al. (MO not seen, UC). DELETIONS FROM THE FLORA Elaphoglossum peruvianum (L. D. Gómez) Mickel (Dryopteridaceae) Treated by Mickel (in Tryon & Stolze 1991:170, under Peltapteris), but now regarded as a heterotypic synonym of Elaphoglossum moorei (E. Britton) H. Christ, according to Moran and Mickel (unpublished ms.); we also subsume Peltapteris in Elaphoglossum. Megalastrum yungense (H. Christ & Rosenst.) A.R. Sm. & R.C. Moran (Dryopteridaceae) The specimen of M. yungense cited in Fl. Peru (Tryon & Stolze 1991:14), D. Smith 4424 (MO not seen, NY, UC), is actually M. biseriale (Baker) A.R. Sm. & R.C. Moran, so M. yungense is not yet known from Peru. ACKNOWLEDGMENTS We thank Jasivia Gonzales for information regarding species of Sticherus in Peru, an unpublished part of her dissertation. We also thank curators of herbaria at HUT and MO for loan of specimens and for sending digital images, and two reviewers for helpful comments and suggestions on this manuscript.
