New insights into the phylogeny of Sinocarum (Apiaceae, Apioideae) based on morphological and molecular data.

ABSTRACT: Sinocarum is a Sino-Himalayan endemic genus of Apiaceae and distributed in high-elevations from Nepal to SW China. In this study, morphological characteristics were combined with nuclear internal transcribed spacer (ITS) and two chloroplast DNA (cpDNA) intron sequences (rpl16 and rps16) to determine the phylogenetic placement of Sinocarum and the infrageneric relationships between five Sinocarum species. The results confirmed that Sinocarum was a polyphyletic group separated into two clades, Acronema and East Asia clades. S. coloratum, the generic type of Sinocarum, S. cruciatum, S. vaginatum and S. filicinum are in the Acronema clade. Among them, the first three species are clustered into a subclade
