1. Phanera bohniana (H.Y.Chen) K.W.Jiang, S.R.Gu & T.Y.Tu , comb. nov.

≡ Bauhinia bohniana H.Y. Chen (1938: 129)

Type: — CHINA. Yangtze watershed , Prefectural District of Likiang [Lijiang], eastern slopes of Likiang [Lijiang] Snow Range, at Takoo [Daju], May to October 1922, J. F. Rock 3905 (see notes) [holotype A00059758 (image!); isotypes E00313591 (image!), NY00038224 (image!), US00001263 !] .

Distribution: —Endemic to China, it occurs in Lijiang, in the province Yunnan.

Notes: —Wundelin et al. (1987) placed Bauhinia bohniana in a monotypic section of subg. Phanera , viz. sect. Pseudobauhinia Wunderlin, K. Larsen & S. S. Larsen (1987: 25). They also indicated in their discussion that although B. bohniana differs from other tendrilled-lianescent species of subg. Phanera in its shrubby habit without tendrils, it is clearly a derivative of subg. Phanera due to the similarity in flower morphology (viz. fertile stamens 3 and staminodes 6 or 7). The phylogenetic results based on nuclear ITS sequences in Hao et al. (2003) also supported that this species is a member of subg. Phanera . However, the phylogenetic results based on the plastid trn L-F region in Sinou et al. (2009) showed that B. bohniana was nested within the clade of Bauhinia s. s., Sinou et al. (2009) thus argued that B. bohniana should be better considered as a member of Bauhinia s. s. We traced the voucher specimens used in both studies and confirmed that the sample of Y.-F. Deng 14097 (IBSC) used by Hao et al. (2003) was correctly identified, whereas A. W. Douglas & S. Lewis 766 (MEL) used by Sinou et al. (2009) was a misidentification of Bauhinia brachycarpa Wallich ex Bentham in Miquel (1852: 261) of Bauhinia s. s. Therefore, here we make the new combination to transfer B. bohniana to Phanera .

In the protologue of Bauhinia bohniana, Chen (1938) cited the holotype as Rock ‘2905’ rather than ‘3095’, we traced the type specimens of B. bohniana , and confirmed this should be a typo, and thus it is corrected here.
