Systematic studies on the Telephium clade (Crassulaceae)

对红景天属、HyloTelephium属、Orostachys属、Meterostachys属、Sincrassula属、红景天属等植物的种类进行了系统研究。属于Orostachys组的Orostachys Schoenlandia的种由一个支系组成，与Sincrassula的种组成一个大的分支，而不是Orostachys组的其余种[即Orostachys组和Appendulata组的种]。以单性雄蕊和基部合生花瓣为特征的舍恩兰组的种与Orostachys的其他种明显分开，被合理地归入一个单独的属，命名为kungia。此外，还对北美地区植物区系景天属植物进行了细致的研究，并对其分类进行了修订。结果将出现在北美植物群中的景天科植物上。

Systematic studies were made on the species in Telephium clade belonging to the genera Sedum, Hylotelephium, Orostachys, Meterostachys, Sinocrassula, Rhodiola and others. The species belonging to Orostachys section Schoenlandia consists of a single clade, and which involve in a large clade with the species of Sinocrassula not the remaining species of Orostachys [i.e., those in sections Orostachys and Appendiculata]. The species of section Schoenlandia, which are characterized haplostamony and basally connate petals, are distinctly separated from the other species of Orostachys, are reasonably classified into a separate genus named Kungia. Several papers are now under preparation.As a side work the species of Sedum of the Flora of North America region were critically studied and revised the taxonomy. The results will be appeared in the Crassulaceae in the Flora of North America.
