“…This extended distribution matches our records, but we have not seen specimens from Paraguay. Labiak et al (2008), Cacharani et al (2014, 2016), and Ponce and Arana (2018) confused this species with Serpocaulon triseriale in the Argentine Flora (Sanín et al, 2019b).…”

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.
