Abstract

Nucleotide sequences of the nuclear rDNA ITS regions were determined in 20 species of the subfamily Sedoideae (Crassulaceae). The phylogenetic relationships of these species with other members of the subfamily, occurring mainly in Southeast Asia, were analyzed. It was shown that the genus Orostachys was not monophyletic; its type subsection was significantly included into the clade of the genus Hylotelephium. Synapomorphic substitutions and indels, specific for the subsection Orostachys, were detected in ITS1. Sister relationships were established between clades Aziopsis and Phedimus, based on which they can be recognized as isolated genera.
