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.
