| 英文摘要 | Polystichum cavernicola L. B. Zhang & H. He, a new pteridophyte species is described and illustrated from a karst cave in southern Guizhou, China. It is a member of Polystichum sect. Haplopolystichum (Dryopteridaceae). A phylogenetic analysis based on the chloroplast trnL-F sequences shows that the new species is most closely related with P speluncicola, a species also described from a karst cave in southern Guizhou. Morphologically, P cavernicola is most similar to P speluncicola. The important morphological differences between P cavernicola and P speluncicola include that P cavernicola has narrow-type microscales on the abaxial laminar surface, its pinnae are chartaceous and have auriculate acroscopic bases, and its lamina is broadest near the midpoint, whereas P speluncicola has broad-type microscales on the abaxial laminar surface, its pinnae are subcoriaceous and have rounded, non-auriculate, acroscopic bases, and its lamina is broadest above the middle. The spores of P. cavernicola have verrucate sculpturing on the perispore, whereas those of P. speluncicola are cristate with numerous spinules on its perispore. Polystichum cavernicola is endemic to a single karst cave in southern Guizhou and is considered to be Critically Endangered (CR) based on IUCN Red List criteria. |
