A taxonomic revision of the genus Selaginella (Selaginellaceae) from Nepal
1Abstract
The present paper deals with the taxonomy of Selaginella from Nepal based on the examination of herbarium collections housed in major herbaria of Europe and Asia (with additional collections from virtual herbaria). A total of 25 species are recognised here, while Selaginella trichophylla and S. laxistrobila are two new records for the flora of Nepal, India (Sikkim) and Bhutan; Selaginella monospora var. ciliolata is synonymised to S. trichophylla; detailed descriptions, distribution and ecology and IUCN conservation status assessments (based on literature) are presented. For most of the species, illustrations of the leaves and strobili are provided for identification of the morphologically similar taxa.
Introduction
Selaginella P. Beauv. is the largest genus of lycophytes, with more than 700 species distributed all over the world but with highest diversity in the tropics (Jermy 1986, Zhou et al. 2015, PPG I 2016, Weststrand and Korall 2016). The Himalaya is one of the diversity centers of ferns and lycophytes of the World. Alston (1945) published the first account of Indian (including Nepalese) Selaginella P. Beauv. Earlier Don (1824), in his “Prodromus Florae Nepalensis”, described seven species in Lycopodium L., including species of heterosporus Selaginella. Thapa (2002) listed 23 species of Selaginella. Fraser-Jenkins et al.’s (2015) revision of Nepalese Selaginella also recognised 23 species.
The purpose of our study was to revise the taxonomy of the genus Selaginella of Nepal, providing a taxonomic treatment with diagnostic keys by macro-morphological characters.
Material and methods
This study was based on materials deposited at the following herbaria: AAU, B, BM, E, GH, K, KATH, KUN, KYO, L, P, PE, TI and US (herbarium acronyms follow Thiers 2019). Images of type specimens of all species from Nepal and neighboring countries were studied by accessing those at E (http://data.rbge.org.uk/herb), K (http://apps.kew.org/herbcat/gotoHomePage.do), P (https://science.mnhn.fr/all/search), B (http://ww2.bgbm.org/herbarium/default.cfm), GH (https://huh.harvard.edu/collections/gray.html), US (http://collections.si.edu/search/results.htm), L (https://bioportal.naturalis.nl) and JSTOR Global Plants project database (https://plants.jstor.org). It is worth noting that part of the collections from Edinburgh Botanic Garden (E) and British Natural History Museum (BM) were borrowed and carefully examined in the Herbarium PE (Beijing). About 350 herbarium specimens, including types for most species associated with taxonomy of Selaginella from Nepal, and many photos of the herbarium collections from KYO and TI provided by Mr. C.R. Fraser-Jenkins, were checked.
Morphological characters, such as ventral (lateral), dorsal (median) and axillary leaves were carefully observed. The morpho-photographs of the plants were taken with a Nikon DXM 1200F camera connected to a stereomicroscope (Nikon SMZ 1000) and computer and measurement was done by D 3.10 (http://www.nikoninstruments.com).
Descriptions of the species follow the form of Zhang et al. (2013), with minor changes, and were prepared based on examined dried herbarium specimens from Nepal and neighboring countries. IUCN categories (IUCN 2001) are based on published data/assessments following Fraser-Jenkins et al. (2015).
The distribution information was gathered from herbarium specimens, and literature.

Note.
We examined the type and general collections in herbaria PE, KUN and PYU for S. trichophylla and S. monospora var. ciliolata: the taxon described as S. monospora var. ciliolata W.M. Chu (in Chu 2006) and listed in the “Uncertain taxa” in Flora of China (Zhang et al. 2013: 66) has many similarities in morphological features with S. trichophylla. The only distinct feature is the spinules on the upper side of the leaves, but these are not always present and it is likely that this trait is associated with a more humid habitat.

Note.
As reported by Fraser-Jenkins et al. (2015), S. tenuifolia is a rather uncommon low to mid altitude species, and widespread from Himalaya to Thailand. In our study (data not published) two collections were included, one from Nepal (T. Nakaike 3065), and another from SW Xizang (PE-Xizang Expedition PT6280). Examined samples were studied on three grounds: gross morphology, morphology of spores and molecular data. Results of gross morphology did not show big differentiation in morphology features for examined samples (incl. observation of ventral and dorsal leaves, shape of leaf margin, strobili, ventral and dorsal sporophylls. Ventral leaves broadly overlapping stem and branches, margin denticulate; Dorsal leaves: ovate, at apex aristate, margin denticulate. Strobili oval in shape; ventral and dorsal sporophylls at margin denticulate.
In both examined collections megaspores on the proximal and distal surfaces are covered with irregularly sized verrucae, the main surface is vermiculate, micro-sculptures are dense spinulose. Microspores on the proximal and distal surfaces are covered with irregularly sized verrucae, micro-sculptures are echinulate.
The molecular data also support the results of morphological studies.
As a result, we consider the distribution of the species not only at low and medium altitudes but also in the highlands.
