Hello Satish ji,
I would like to reply the email regarding Habenaria rariflora & H. grandifloriformis a little in detail. I would like to clarify exactly what I really meant about the leaves as a key for identification.
Following is what I feel & would request for further comments.
The image attached with your email is certainly H.grandifloriformis.
For the very basic difference between the leaves of the two species I would like to quote from the Habenaria key by none other Fr. Santapau & Kapadia.
Am attaching few pages from the key. (Sincere apologies regarding the file sizes but the text was not visible in lower resolution).
The clear distinction in the species is that the leaves of H.rariflora are oblong lanceolate - thin - not flat on the ground. On the contrary H. grandifloriformis has leaves that are ovate - fleshy - flat on ground.
Regarding the endemism of H. rariflora in Karnataka - Kerala mentioned by Garg ji in one of the email, I would like to again quote Fr. Santapau from Flora of Khandala about the abundance ( kindly refer the flora).
Though I do not have an image of H.rariflora, I had seen them on an elevated plateau near Kamshet - near Lonavala. The flowering season coincided with that of H.hyneana.
Have put forth my observations regarding the two species. Would request for further comments.
