“…By creating a smaller, more manageable genus, Smith et al (2006) stimulated research on the group (Chaves-Fallas et al, 2015). Since the 40 names established by Smith et al (2006), new taxa and new combinations have been published for species in Argentina (Sanín et al, 2019a), Brazil (Labiak & Prado, 2008;Schwartsburd & Smith, 2013;Sanín & Salino, 2020), Colombia (Sanín & Torrez, 2014;Sanín, 2015Sanín, , 2018, and Costa Rica (Rojas-Alvarado & Chaves-Fallas, 2013;Chaves-Fallas et al, 2015).…”

“…This is a hybrid between Serpocaulon fraxinifolium (with pinnate lamina) and S. ptilorhizon (with pinnatisect lamina) and is known only from the type locality. Rojas-Alvarado and Chaves-Fallas (2013) Plants terrestrial or rupicolous. Rhizomes 5 mm diam., short-creeping, whitish brown to green, pruinose or sometimes only faintly pruinose; phyllopodia 1 cm apart, 4-5 mm long.…”

“…Many authors have mentioned the need for an exhaustive taxonomic revision of species now included in Serpocaulon (Moran, 1990(Moran, , 1995Smith et al, 2006;Kreier et al, 2008;Labiak & Prado, 2008;Schwartsburd & Smith, 2013;Sanín, 2018). attempted a revision of the Polypodium loriceum L. group (which basically corresponds to Serpocaulon) based on morphological characters, and several new taxa have been described or combined since then (Labiak & Prado, 2008;Rojas-Alvarado & Chaves-Fallas, 2013;Schwartsburd & Smith, 2013;Sanín & Torrez, 2014;Chaves-Fallas et al, 2015;Sanín, 2015Sanín, , 2018Sanín et al, 2019a;Sanín & Salino, 2020). However, the proliferation of names is one of the pitfalls faced by taxonomists when synthetic or revisionary works are unavailable for a particular group (Moran, 1987).…”

We present a taxonomic revision of Serpocaulon A. R. Sm. (Polypodiaceae), a tropical American fern genus. Our work is based on a morphological analysis of 56 characters recorded from 2167 specimens deposited in 41 herbaria. Field trips were carried out in Argentina, Bolivia, Brazil, Colombia, Costa Rica, Ecuador, Panama, and Peru, where observations on the habit and habitat of several species were made. Digital images were also consulted. A total of 260 names were found and their nomenclatural types were studied, resulting in the lectotypification of 47 names (first-step 30, second-step 17 names). We recognize 37 species and five hybrids in Serpocaulon; one of the hybrids is given a new status (S. ×semipinnatifidum (Fée) A. R. Sm.) and another one is described (S. ×tabuleirense D. Sanín & Salino). Moreover, 19 names are newly synonymized, five species are excluded, 17 names are considered as of uncertain application, and five as nomina nuda. We document for 22 species a total of 62 chorological novelties in different countries. The elevational range of the genus is 0–4200 m. The Andes of Ecuador and Colombia are the main center of diversity and endemism; secondarily, the Atlantic Rain Forest of Brazil has five endemic species. We provide a taxonomic key, descriptions, discussions, local names, uses, illustrations, photographs of the plants in the field, microphotographs of the rhizome scales and the spores, and distribution maps of all species.

Serpocaulon triseriale (Sw.) A.R. Sm. is considered the most widespread species in the genus. It has been recorded from south of Mexico to Bolivia, Paraguay and Brazil. Here, we expand its distribution by reporting a new record from Salta province, Argentina, based on material that was previously misidentified as S. polystichum (Link) A.R. Sm. We compare the S. triseriale and S. polystichum with their relatives (S. attenuatum (Humb. & Bonpl. ex Willd.) A.R. Sm., and S. rex Schwartsb. & A.R. Sm.), providing photographs of the plants in the field, SEM images of the spores and light photos of the rhizome scales to discriminate S. rex from S. triseriale. In addition, distributional records are included.

“…Serpocaulon A.R.Sm. is a Neotropical genus of Polypodiaceae with 42 species and three known hybrids (Smith et al 2006, Labiak & Prado 2008, Rojas-Alvarado & Chaves-Fallas 2013, Schwartsburd & Smith 2013, Sanín 2014. The genus is characterized by a suite of morphological characters that includes long-creeping rhizomes, clathrate scales, veins regularly anastomosing (goniophlebioid), and areoles chevron-shaped with a single, free, included veinlet (Smith et al 2006).…”

Serpocaulon × manizalense: a new hybrid between simple- and pinnate-leaved species of Serpocaulon (Polypodiaceae) from Colombia

During a revision of Serpocaulon from Colombia, a new hybrid was found between S. adnatum and S. levigatum near to Manizales city, which is described and illustrated herein. Qualitative and quantitative spore and macro-morphological characters were evaluated using principal component analyses to distinguish the new taxon. Our results suggest that the perispore with leasura, lamina width, rhizome diameter, blade dissection and number of pinnae are important characters to distinguish S. × manizalense. This is the first record of a hybrid between a simple and pinnate-leaved species in Serpocaulon, which is considered to be Critically Endangered (CR).
