Michelia mediocris Dandy. In: Xia et al. (2008: 85), p.p. quoad syn. Michelia rubriflora Y.W. Law & R.Z. Zhou.

Note.

While Michelia rubriflora is noted as a synonym of M. mediocris in Flora of China ( Xia et al. 2008), the present authors agree with Wang and co-authors that Michelia rubriflora can be more than sufficiently differentiated from M. mediocris by the diagnostic features of these two species included in Table 1 of their paper ( Wang et al. 2005), to substantiate its species status. A more comprehensive analysis of their differentiating features is compiled in Table 7 below. Michelia rubriflora also does not key out with the original validating description for M. subulifera ( Dandy 1930:212), with which it shares synonymy under M. mediocris in Flora of China. Evidently an independent species, Michelia rubriflora is transferred in the present paper to the genus Magnolia by reason of the past reduction of the remaining genera of subfamily Magnolioideae to that genus.
