A revision of Lespedeza subgenus Macrolespedeza (Leguminosae) in China.

This paper is intended as a complement to the account of subgenus Macrolespedeza of the genus Lespedeza for the Flora of China treatment (Flora of China vol. 10. Fabaceae. Editors: Z. Y. Wu, P. H. Raven and D. Y. Hong in preparation). We provide here an introductory note on the subgenus in China, a key to the species, bibliography of all the species and synonyms, and taxonomic notes especially on the species described by Ricker (1942, 1946) and L. thunbergii (DC.) Nakai. Most of these items are not included in the Flora of China treatment. This is also a continuous paper from our previous revision of Chinese Lespedeza subgenus Lespedeza (Ohashi et al. 2009a). The present circumscription of the genus Lespedeza was proposed by Schindler (1913) who modified the subgenus Lespedeza in the sense of Maximowicz (1873). Schindler’s generic concept has been followed in the recent general systems of the tribe Desmodieae in Hutchinson (1964), Ohashi et al. (1981) and Ohashi (2005). Maximowicz (1873) created section Macrolespedeza under subgenus Lespedeza. Schindler (1913) adopted the section under genus Lespedeza. Nakai (1939) divided section Macrolespedeza into two sections Macrolespedeza s.s. and Heterolespedeza. A Revision of Lespedeza Subgenus Macrolespedeza (Leguminosae) in China
