attached a wrong picture Rajesh ji?

I am sorry Nidhan ji. It was my mistake that I went for saying it I. devendrae because it looked similar. I cant find any ref of Euphrasia officinalis on The plant list, FoI , Vof Book, Consise flora of Himalayas book. Sir, do you have a link to cite the species. I can see Euphrasia himalayica (on FoI & in concise flowers of Himalaya book) is that the same?

Nidhan ji,
I have similar sighting; thought it could be Euphrasia platyphylla as per K R Keshava Murthy's VoF book.
Could these E. officinalis and E. platyphylla be close species ?

Regards.
Dinesh

E. officinalis is not an Indian species, and is not found in the Himalayas. The description and picture of Euphrasia himalayica seems to agree well with the plant found in the Valley of Flowers. Don't know about E. platyphylla, so cannot comment. However, Euphrasia is a notoriously difficult genus.

Yes multiple species described because of apomictic nature like Taraxacum. The species are difficult to distinguish unless closeups with hairs are shown. In E. himalayica the leaves and bracts are mostly fallen by anthesis. Also yellow corolla throat and reddish lines on upper lip suggest E. platyphylla.
