Bauhinia x blakeana :: Hooghly, West Bengal

[surajit koley]

Dear Friends,

Yesterday, I have had a short chat with Dinesh-ji (in the 'facebook' group 'Indian Flora') over the identification of this Bauhinia sp. He identified it as *Bauhinia x blakeana* or the 'Hong Kong Orchid Tree'. Dinesh-ji also provided me links (given below) of the two earlier 'efloraofindia' posts where Garg Sir and Gurcharan Sir discussed the identity of this plant.

Today, i took some more photos of the same plant that i attach herewith.

Feedback from another thread https://groups.google.com/forum/?hl=en&fromgroups#!topic/indiantreepix/WUz7SIl0pt0:

"Thank you for drawing my attention to the fact that B. blakeana is a sterile plant. I also read, in January, about the sterile flowers of B. blakeana in wikipedia and other websites.

But there is a discussion at - http://davesgarden.com/guides/pf/go/53664/ where someone claims that it bears seedpod. Again there is an image claiming to be seedpod of the same plant - http://www.hear.org/starr/images/image/?q=030702-0067&o=plants

So, if it is not the B. x blakeana then my earlier post (https://groups.google.com/forum/?fromgroups#!searchin/indiantreepix/bauhinia$20x$20blakeana/indiantreepix/2fer1UHmLTI/X2wqPw3W38kJ) should also be some other species, might be B. variegata." from Surjit ji.

Sir,

I think now that this is NOT Bauhinia blakeana. Because, later i witnessed seedpod growing on this tree and i uploaded the same in another post - https://groups.google.com/forum/?fromgroups#!searchin/indiantreepix/seedpod$20-$20bauhinia$20x$20blakeana/indiantreepix/WUz7SIl0pt0/7F1d4il4Sz8J

I confirm hereby that images from both of my posts were recorded from the same tree.

Thank you & regards,

Yes Sir, this is Bauhinia x blakeana, for it does not produce fruit or seeds.

(I did keep this particular tree under my observation for years.)

Thank you for taking care.

Dear Surajit ji

Then what about your post on April 25, 2012 at 9:09:51 PM, where you talked about seed pods?

I apologize Sir, for my grave mistake. I entirely forgot the other follow-up thread. It is Bauhinia variegata L..

A detail on the three confusing spp. can be found at https://www.researchgate.net/publication/51201005_Hybrid_origin_of_Bauhinia_blakeana_Leguminosae_Caesalpinioideae_inferred_using_morphological_reproductive_and_molecular_data.

Thank you very much., Sir, have a nice day
