I have updated efi page on Bauhinia

Attempts have been made to incorporate most of the species available in India & nearby areas with details & keys directly or through links.

Efloraofindia page links are at the bottom of the page.

Any comments are welcome.

I have two suggestions.
The images said to be of Bauhinia glauca are actually of Bauhinia glauca subsp. tenuiflora. Bauhinia glauca subp. glauca is not found in India. In subsp. tenuiflora the length of the receptacle is more than the respective pedicel. This character is clearly visible in the images.
Secondly if you put Bauhinia racemosa as a synonym of Bauhinia vahlii there might be a confusion.
Actually it should be Bauhinia racemosa auct. non Lam. 1785: Vahl, Symb. Bot. 3: 56, t. 62. 1794.
Simply you can put Bauhinia racemosa Vahl i.e. it is not Bauhinia racemosa Lam. (Bidi Leaf Tree).
Thanks a lot, ...
As per Flora of China, range of Bauhinia glauca subp. glauca is shown in India also.
Could you pl. through some light on this aspect ?
Bauhinia- Pollination and floral biology :
.......................... Concerning Bauhinia I found this: 
The relationship between the pollination biology of a tropical plant, Bauhinia pauletia, and the foraging strategies of the nectarivorous bats visiting it was studied. At least two bat species are pollen vectors, Phyllostomus discolor and Glossophaga soricina. Artibeus jamaicensis and Sturnira lilium were also captured near Bauhinia flowers. Larger bats (P. discolor) drain flowers of nectar and forage in groups, while smaller bats (G. soricina) make brief visits and forage independently. These foraging strategies should optimize energetic gain for the bats and promote outcrossing for the plant. Bauhinia pauletia is self—compatible, but is found where conditions favor outcrossing. Andromonoecism (the presence of hermaphrodite and male flowers) in this species appears to be an adaptation to pollination by large pollinators that also promote outcrossing.
Pollination and floral biology of seven species of Bauhinia were analyzed between 1982 and 1983 in different Venezuelan plant communities. Bauhinia species are grouped in two sections: Pauletia, which includes trees, and Tylotaea, which includes lianas. The species of sect. Pauletia included in this study (B. aculeata, B. multinervia, B. pauletia, B. ungulata) have comparatively large, white flowers, while the species of sect. Tylotaea (B. glabra, B. guianensis, B. rutilans) exhibit different colors of flowers and variations in form and color of the upper petal. Nectar analyses were made for six Bauhinia species for sugar and amino acid composition. The species of sect. Tylotaea produce less nectar with a higher sugar concentration than those of sect. Pauletia. Hexose is dominant in species of sect. Pauletia except in Bauhinia aculeata, where sucrose is dominant. The species of sect. Tylotaea have comparatively small diurnal flowers and are visited by a great variety of bees, wasps, butterflies, and hummingbirds; those of sect. Pauletia are mainly nocturnal and bat-pollinated, but Bauhinia aculeata showed different behavior and could be intermediate between the two sections. The flower morphology, floral biology, pollinator species, nectar composition, and secretion tend to be associated with the life form of the two sections of Bauhinia.
