RESUMEN
Cyrtomiumadenotrichum Y. Nong & R.H. Jiang (Dryopteridaceae), a new species from Guangxi, China, is described and illustrated. This new species is similar to C.nephrolepioides (Christ) Copel., C.obliquum Ching & K. H. Shing ex K. H. Shing, C.sinningense Ching & K. H. Shing ex K. H. Shing and C.calcis Liang Zhang, N.T.Lu & Li Bing Zhang in having erect rhizomes, dense, leathery lamina and rounded sori, but it can be easily distinguishable by its stipe sparsely glandular, base obvious oblique, basiscopic base truncate, acroscopic base auriculate or ovate.
RESUMEN
Walsuraguangxiensis (Meliaceae), a new species from Guangxi, China, is here described and illustrated. The new species is easily distinguishable from the other two Chinese members of the genus by its petals being pale yellow, filaments being connate into tubes above the middle, the berry being oval and glabrous. An identification key of Walsura for 17 species is also provided.
RESUMEN
PREMISE OF THE STUDY: Microsatellite markers were developed for Ilex kaushue (Aquifoliaceae), a medicinal plant with extremely small wild populations that exists in fragmented habitats, to assess and protect its genetic diversity. METHODS AND RESULTS: Using 454 GS FLX Titanium sequencing, 16 microsatellite primer sets were isolated and characterized. Fifteen of these markers were polymorphic. The number of alleles per locus ranged from one to nine across 22 individuals from both cultivated and wild populations. The observed and expected heterozygosity in these two populations ranged from 0.000 to 1.000 and from 0.000 to 0.785, respectively. CONCLUSIONS: These markers will be useful in studies on genetic diversity of I. kaushue.
