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!
