A new name, Magnolia kwangnanensis S.G.Chen & Q.W.Zeng sp. nov., and a new type are designated to accommodate the original description. Here we provide new data and a detailed morphological description for this species. Notes are also presented on its habitat, pollen morphology, and conservation status. Key words: Magnolia, Magnoliaceae, taxonomy, new species, China 1. Introduction The name Magnolia odoratissima Y.W.Law & R.Z.Zhou (Law & Zhou, 1986; Law, 1996, 2004; Zhang, 2004; Law & Xia, 2006; Cicuzza et al., 2007) is currently in use for a species of Magnoliaceae distributed in Guangnan County, in southeastern Yunnan Province, China. It is endemic to China and has been listed in the Grade II protected plants in the National Key Protected Wild Plants List (approved by the State Council of China, 1999). Chen and Nooteboom (1993) treated it as a synonym of Magnolia championii Benth. In contrast, Xia and Deng (2002) recognised this species in a revision of Magnoliaceae, and excluded the specimen C.F.Wei & D.Chen 123226 (shown to be Magnolia championii), which was collected from Guangdong Province and cited in the protologue. Recently, one study (Nie et al., 2008) suggested that it was closely related to M. coco (Lour.) DC. based on nuclear .
