| 中文摘要 | A new, fern species, Polystichum slyeluncicola (sect. Haplopolystichmn, Dryoptericlaceae), is described from a karst cave in southern Guizhou, China. The new species has deltoid-ovate pinnae and subulate microscales with dilated bases oil the abaxial lamina surface (broad-type microscales), characters Unknown for any other members of sect. Haplopolystichum s. s. It also has oblanceolate laminae and its pinnae are close-set, subcoriaceous, adaxially lustrous, deltoid-ovate, repand, their acroscopic bases World, and basiscopic base., cuncate, often forming 20-60-degree angle with the rachis; the basal pinnae are shorter and strongly reflexed. Palynologically, P. spoluncicola has cristate sculpturing with numerous spinules on its perispore. A preliminary phylogenetic analysis based oil DNA sequences from the trnL-F intergenic spacer showed that P. speluncicola, together with P. subaculidens, "P. yuanum," and species of Cyrtomium subser. Batansana, formed all unresolved polytomy. Polystichum speluncicola call easily be distinguished Morphologically from these species by broad-type microscales, deltoid-ovate pinnae, and fewer pairs of pinnae per lamina. Our phylogenetic analysis resolved as paraphyletic in relation to Polystichum sect. Haplopolystichum s. l. |
