Five Selaginella species (i.e, S. gioiae, S. papillosa, S. pubimarginata, S. rostrata, and S. xanthoneura) from Neotropical rainforests of South America are described and illustrated as new, while S. surucucusensis, originally recorded only from Brazil, is redefined to account for species’ morphological characters throughout its expanded distribution range and also a novel illustration is provided for it. Inferred taxonomic affinities and conservation assessment are offered for species here treated. Selaginella gioiae is native to Colombia, Ecuador, and Peru, and S. xanthoneura is so far only known in Colombia, whereas S. surucucusensis is now known to occur in Colombia and Venezuela in the north-central part of South America. These three species are included in the “Selaginella flabellata group” based on their habit, stem shape, rhizophores position, and mega- and microspores color, and ornamentation. Selaginella papillosa, S. pubimarginata, and S. rostrata are native to Venezuela. Selaginella papillosa and S. pubimarginata morphologically belong in the “Selaginella deltoides group” based on their habit, stem type, shape of lateral leaves and their indument type distributed on upper surface of the leaf lamina. On the other hand, S. rostrata is considered to be a member of the “Selaginella microdonta group,” which is centered in the Guiana Highlands, based on its habit, stem type, and leaf size and shape, and for which a key to identify species is provided. Finally, all species threated here are classified in subg. Stachygynandrum based on their heteromorphic leaves, mostly quadrangular strobili, and monomorphic sporophylls shape (except for S. rostrata that has slightly dorsiventral and flattened strobili with somewhat heteromorphic sporophylls).

“…Selaginella is heterosporous. A number of studies on the morphology of megaspores and microspores (especially megaspores) of Selaginella have been published (e.g., Zhou et al., 2015 ; Valdespino et al., 2015 ; Valdespino et al, 2018a ; Valdespino et al., 2018b ; Valdespino, 2015 , 2017a , 2020 ; Bauer et al., 2016 ; Wang et al., 2018 ). These studies showed that Selaginella holds extremely high diversity in spore morphology.…”

“…Studies about the genus in Brazil have mainly been concentrated on the Atlantic Forest and Amazonia (Bautista 1974a, b, Castellani & Freitas 1992, Hirai & Prado 2000, Prado & Freitas 2005, Prado & Hirai 2008, Heringer et al 2016, Valdespino 2015a, b, Valdespino et al 2015, Valdespino et al 2018a, b, Valdespino 2020). Nevertheless, records from the Cerrado vegetation have been reported in the flora of the Distrito Federal (Hirai 2007), Minas Gerais (Heringer et al 2016), and recent inventories in Maranhão (Almeida et al 2020, Fernandes et al 2022.…”

“…This work, however, does not include species descriptions, except for new taxa. Generally, the works used to identify neotropical Selaginella species are original descriptions and floras (Alston et al 1981, Jermy 1990, Webster 1992, Valdespino 1992, Cremers & Boudrie 2007, Zhou & Zhang 2015, Heringer et al 2016, Valdespino 2015a, b, Valdespino et al 2015, Valdespino et al 2018a, b, Valdespino 2020, Valdespino et al 2022a, b, Góes-Neto et al 2023.

This work is a floristic study of Selaginella in Maranhão. The species survey is based on collections from fieldwork conducted between April 2006 and February 2023 and specimens from Maranhão deposited at the CCAA, HBRA, MG, and SLUI herbaria. Ten species were identified: Selaginella conduplicata, S. convoluta, S. erythropus, S. flagellata, S. gynostachya S. marginata, S. minima, S. radiata, S. simplex, and S. sulcata. We report the first record of S. gynostachya for Maranhão and the Cerrado domain in Brazil. Until now, this species was only known from areas of Amazonia. We provide a map with records, an identification key, and comments about the identification and geographic distribution of Selaginella species in Maranhão state. For the new record, we also provide photos.
