Walsuraguangxiensis (Meliaceae), a new species from Guangxi, China.

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.

Development of microsatellite markers in Ilex kaushue (Aquifoliaceae), a medicinal plant species.

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.
