Note.

Manglietia rufisyncarpa is listed as a synonym of M. insignis in Flora of China ( Xia et al. 2008), by Sima and Lu (2009) and by Sima (2011). However, the present authors agree with Wang and co-authors that M. rufisyncarpa can be more than sufficiently differentiated from M. insignis (Wall.) Bl. by the diagnostic characters of these two species compiled by Wang et al. (2004: Table 1 ), to substantiate its independent species status. Additionally, M. rufisyncarpa flowers from April-May whereas M. insignis flowers from May-June ( Liu et al. 2004: 156). Also, among the many Manglietia photos in Magnolias of China, the bright red gynoecium of this species, alluded to in its Chinese name, is particularly noticeable as one of only a few exhibiting this colour, with M. insignis displaying a green gynoecium. Manglietia rufisyncarpa also does not key out with the original validating descriptions for M. maguanica Chang & B.L. Chen, M. yunnanensis Hu or Magnolia shangpaensis Hu, with which it shares synonymy under Manglietia insignis in Flora of China. In view of the above, M. rufisyncarpa is transferred in the present paper to Magnolia , consistent with the past reduction of the remaining genera of subfamily Magnolioideae to the genus Magnolia .
