“…1c. Holttum (1971) and Tryon & Lugardon (1990) illustrated a spore from a New Guinea specimen (Clemens 3125), indicating fewer tubercles (than in Fig 1c) that are randomly distributed on irregular discontinuous ridges. 2.…”

“…They appeared to lack a perispore. However from a survey using both whole spores observed by scanning electron microscopy, and some wall details in sectioned material viewed by transmission electron microscopy, Tryon & Lugardon (1990) Etymology: the genus Stenochlaena from Greek 'stenos' = slender, presumably referring to the pinnae of the very large fronds and 'chlaina' = cloak or mantle, referring to the climbing plants together with their very large sterile fronds cloaking the trunk and canopy of a rainforest host tree.…”

Stenochlaena is a small but widespread genus confined to the tropics and subtropics of the Old World. A key to the species, updated descriptions, distribution-maps, and detailed drawings are provided. Also included is a key to assist in separating several genera that are most often confused with Stenochlaena. There is morphological evidence suggesting that hybrids may exist between several species in Malesia. Although primarily a rainforest genus, the distribution patterns of the various species of Stenochlaena appear closely related to ecological requirements; the hemiepiphytic members of the genus are most frequently present along forest margins in relatively high light conditions with access to a moist soil or an aquatic environment but not necessarily to perpetually humid atmospheric conditions.

“…65 Asian species of Seleginella (for voucher information see Appendix 1) was observed using a QUANTA 200 scanning electron microscope (FEI Co., Hillsboro, Oregon, U.S.A.), and gold-palladium plating was performed using a BAL-TEC SCD 005 cool sputter coater (BAL-TEC, Liechtenstein) at Yunnan University, Kunming, China. Additional data on spore morphology were taken from literature (e.g., Reeve, 1935;Minaki, 1984;Liu & al., 2001Tryon & Lugardon, 1991;Giorgi & al., 1997;Chang & al., 2002a, b;Li & al., 2003;Liu & Yan, 2004, 2005Chu, 2006;Korall & Taylor, 2006;Zhao & al., 2006a, b;Singh & al., 2014).

The largest genus of seed‐free vascular plants Selaginella alone constitutes t he family Selaginellaceae, the largest of the lycophyte families. The genus is estimated to contain ca. 800 species distributed on all continents except Antarctica, with the highest species diversity in tropical and subtropical regions. The monophyly of Selaginella has rarely been doubted, in contrast its infrageneric classification has been contentious. In the present study, based on chloroplast and nuclear DNA evidence, macromorphology, spore features, and/or distribution information, Selaginella is classified into six subgenera: S. subg. Selaginella, S. subg. Boreoselaginella, S. subg. Pulviniella, S. subg. Ericetorum, S. subg. Heterostachys, and S. subg. Stachygynandrum. The latter three subgenera are further classified into six, five, and seven sections, respectively. All of these infrageneric divisions, identified with molecular data, are supported by non‐molecular features. A key to infrageneric taxa is given. Thirty‐seven infrageneric taxa published in earlier literature are lectotypified and classified into those infrageneric taxa here recognized. A nomenclatural account of each infrageneric taxon is given.

“…Mature sporocarps of P. americana have a mean diameter of 2 .67 mm and contain 12-20 megaspores per sorus (Large & Braggins 1989), whereas the corresponding values for P. dracomontana are 1 .58 mm, and 3-5 megaspores respectively . The apical papilla-like laesura (acrolamella) of the megaspores of P. dracomontana is proportionately much longer (at ± 23 %) than its equivalent in P. americana, which has been documented as ± 12 .5 % of the total spore length (Tryon & Lugardon 1991) . Leaf lengths of P. americana range from 15-50(-100) mm (Correll 1956;Large & Braggins 1989;Mickel & Smith 2004), whereas leaves of the new species are no longer than 14 mm, on average attaining < 12 mm .…”
