Isodonxiaoluzhiensis (Lamiaceae, Nepetoideae), a new species from Yunnan, southwest China.

Isodonxiaoluzhiensis, a new species of the tribe Ocimeae in family Lamiaceae, is described and illustrated. The new species is known only from the type locality, Xiaoluzhi village in Luzhijang dry-hot valley of Yimen County, central Yunnan, southwest China. It is characterized by having a procumbent habit, gracile stems and branches, relatively small leaves and flowers, and the phenology of flowering in winter. The morphological comparisons with its putative closest relatives (I.adenanthus and I.hsiwenii) are also presented.

Rubusdianchuanensis sp. nov. (Rosaceae) from Sichuan and Yunnan, southwest China.

Rubusdianchuanensis, a new name for the species previously named as R.vicarius by W. O. Focke in 1911, is proposed. A detailed description, illustrations, and remarks on its phenology, ecology, and geographic distribution are provided. This raspberry (subg. Idaeobatus) is endemic to China and was only found in Sichuan and Yunnan, southwest China. Morphologically, it is most similar to R.ovatisepalus but clearly differs from the latter by having leaf densely white or grey tomentose abaxially, usually leaf-like bracts at the base of inflorescence, 1-6 cm long pedicels, and triangular-ovate sepals with acute to caudate apex.
