  • The chemical constituents of Selaginella tamariscina were studied. From the n-hexane, chloroform and n-butanol soluble fractions, three compounds were isolated by chromatographic purification process. They were identified as lutein, $3{\beta}-cholesterol$ and hinokiflavone by spectral anaylsis(IR, MS, UV, $^1H-NMR$, $^{13}C-NMR$ and DEPT). Lutein and $3{\beta}-cholesterol$ were first isolated compounds from Selaginellaceae and hinokiflavone was a reported compound from this plant.

  • From the chloroform and n-butanol extracts of Selaginella tamariscina, three biflavonoids were isolated by chromatographic separation. Structures of these compounds were determined as cryptomerin B, amentoflavone and isocryptomerin by spectroscopic analysis, and amentoflavone was further identified by comparison with the authentic sample. This is the first report of isolation of cryptomerin B from Selaginellaceae.

  • Selaginella heterostachys Baker (Selaginellaceae), previously known only from southern Japan, China, Taiwan and Vietnam, was found on sunny slopes at forest edges, Gangchon-ri, Chuncheon-si, Gangwon-do. This species is distinguished from the related taxon by ovate lateral microphylls with shallowly cordate base and elongated median microphylls with recurved apex. The local name Gak-si-bi-neul-ikki, meaning of the bride's skirt shape of median microphylls with recurved apex rather than S. nipponica. The morphological characters and illustrations of this species are provided with photographs of the habit.

  • Selaginella vaginata is a common montane species with broad distribution in China and the Himalaya region, and several species that are morphologically similar to S. vaginata are distributed in Asia. The taxonomic revision of S. vaginata and related species was performed by morphological comparison of leaves, strobili, and spores, and phylogenetic analysis. Based on these results, a new species, S. subvaginata, sp. nov., has been identified. Morphologically, S. subvaginata has intermediate form between S. vaginata and S. repanda, which differs mainly in its main stem being erect, dorsal leaves long-ciliolate on inner margin and outer margin denticulate or with 2-4 cilia at base (long-ciliolate on both inner and outer margins in S. vaginata, denticulate on both inner and outer margins in S. repanda), and acroscopic base of ventral leaves long ciliolate (sparsely long ciliolate in S. vaginata, short ciliolate to denticulate in S. repanda). Moreover, phylogenetic analysis using three chloroplast markers(rbcL, atpI, and psbA) revealed that S. subvaginata is a distinct species among the anisosporophyllous species clade in Selaginellaceae.

  • Selaginella austrotibetica, a new spikemoss species from China, is described. The species is epipetric and was found on a moss-covered rocky cliff by a riverbank. Morphologically, it is unlike any anisosporophyllous species in the genus Selaginella. However, it resembles species of the S. sanguinolenta group, especially similar to S. sajanensis in gross morphology, except for the characters of strobilus. The molecular phylogenetic analysis clearly showed that S. austrotibetica was nested within the anisosporophyllous species clade, forming a sister relationship with the clade of S. vaginata and S. xipholepis, and distinct from the S. sanguinolenta group, including S. sajanensis. Although S. austrotibetica is sister to the clade of S. vaginata and S. xipholepis, the species can be clearly distinguished by its sparse leaves on branches, dorsal leaves that are broad-ovate, base obtuse to rounded, margin denticulate or very shortly sparsely ciliolate, and leaves that are slightly thick and shiny. Therefore, we described Selaginella austrotibetica as a new species and discuss its phylogenetic relationships within the genus Selaginella.
