Lespedeza danxiaensis (Fabaceae), a new species from Guangdong, China, based on molecular and morphological data

Lespedeza danxiaensis (Fabaceae), a new species from Danxiashan National Nature Reserve in Guangdong Province, is described and illustrated. The new species is morphologically similar to Lespedeza pilosa, but it can be easily distinguished by its thin leathery leaflets and long peduncles. Phylogenetic analysis based on ITS confirmed that the new species belongs to Lespedeza subg. Macrolespedeza. The new species is the first known species of Lespedeza endemic to Danxia landform and is currently only known from Mount Danxia, Guangdong.

Primulina lianchengensis (Gesneriaceae), a new species from Danxia landform of Fujian, China: Evidence from morphological and molecular analyses

Primulina lianchengensis B.J.Ye & S.P.Chen (Gesneriaceae) is described and illustrated from Fujian Province in the Southeast of China. Then phylogenetic analyses of the genus were presented using nuclear ribosomal ITS and two plastid markers (atpB-rbcL and rpL32-trnL). Morphological analysis indicates that P. lianchengensis is similar to P. danxiaensis, P. depressa, P. lechangensis and P. yangshanensis, but it differs in the base and margin of leaf, petiole, bract, length and shape of corolla, numbers of staminodes and stigma lobe. Molecular analysis reveals that P. lianchengensis is genetically similar to P. danxiaensis and P. yangshanensis.
