  • 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.

  • 일본, 중국, 대만 및 베트남에 분포하는 것으로 알려진 부처손과의 각시비늘이끼 (Selaginella heterostachys Baker)가 강원도 춘천시 남산면 강촌리 저지대에서 발견되었다. 이 종은 선비늘이끼와 유사하나 측면의 소엽이 난상이며 기부가 심장저이고, 중앙부의 소엽은 길며 정단부가 구부러진 점으로 구별된다. 국명은 선비늘이끼보다 중앙부의 소엽이 구부러져 각시의 치마와 비슷하여 각시비늘이끼라고 신칭하였다. 각시비늘이끼의 형태적 특징을 기재하였고, 도해와 생태 사진을 첨부하였다.

  • 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.
