Dear Ninad

Thanks a lot for sharing. This is one of the very few Habenarias in
India which has yellow flowers. Till evening I thought that this plant
is

Habenaria marginata Colebr. in W.J.Hooker, Exot. Fl.: t. 136 (1824).

but when I saw Dr. Almeida's Flora of Maharastra, I got shocked and my
over 8 years of Orchid research went in vain, because he calls this
plant as

Habenaria heyneana Lindl., Gen. Sp. Orchid. Pl.: 320 (1835), Almeida,
Orchidaceae in, Flora of Maharastra vol 5A, t. 18, f. 52, p. 58
(2009).

and according to him this is the plant which is called Tooth Brush
Orchid. At first I thought there was a mistake in attaching the pics
in the book, but then I realised that he has described this plant with
yellow flowers, but the original H. heyneana which I had known was
having white flowers which were secund.

God save me!

Dear Pankaj Sir,
Thanks for correction but I even checked on Flowers of India
Mr. Pravin Kawale's photo which was identified by Pravin ji and Mr.
Navendu Page.

There was no need to resurface this one. It was already identified as
Habenaria marginata Colebr. I respect Dr. Almeida so I dont wish to
comment on his work....

For the convenience of all I am attaching the type of both Habenaria
marginata and Habenaria heyneana. There is no need to check Flora of
Bombay Presidency by Cooke if the images of Type are available for
free on internet.

I would certainly like to check the past floras to know where the
mistake arose from.

Pankaj

With due respect for everyone i want to say somethig...

 i have seen that flora too and i know Picture of Habenaria marginata is labeled as H.hyneana...it is just printing mistake 

i was suppose tell sir about this but neither i am researcher,expert  nor taxonomist so i have no authority to say anything so i kept quiet, but i wonder when people doubt on identification given by expert on the basis of flora ..why they do not think that there can be error or printing mistake in flora

Sorry my attachment didnt upload. I am uploading it again.

I agree with Ms. Smita's point, it can be typographic error. Sometimes
just today happened with me, I wrote description of an orchid under
the name of different species unknowingly.

But, my point was something different. To confirm the identity of a
species we should first try to look at the original description and
then we may think of looking the latter descriptions from other floras
or whatever publication we get. Other floras may be wrong, but the
first description or the type description is the best thing to look
into. Now a days lots of original references are available on net.
Trust me, they are more easily available than Flora of Maharastra!! of
Flora of India fascicles by BSI....that too for free!! You just need
to search on internet.

Yes, for daily use purpose, you may use the local floras whatever is available.
Thank you and hope my point will be taken in good spirits.

Regards
Pankaj

The type images did get uploaded both times. I have not seen Almeida's Flora and don't know whether the mistake is just in attaching image/illustration, or he has committed errors even in description. If it is only a matter of wrong labelling of image, it can be easily understood. I remember when found illustration of Prinsepia utilis wrongly labelled in Wealth of India. In Royle's original book on Himalayan plants, he had called left image as b and right as a whereas the legend was opposite, so that name of left picture appeared under the right picture. While this was copied in wealth of India Prinsepia utilis carried the name of another plant (perhaps Prunus cornuta). I wrote about it to the Editor of Wealth of India, who first tried to give me the explanation, but when I gave him the real reason for error in Wealth of India, He promised to correct it. I don't know whether it was carried out.
