Didymocarpus pedicellatus from Uttarakhand : Attachments (3). 3 posts by 3 authors.
Didymocarpus pedicellatus R.Br. (Gesneriaceae) is one of the most beautiful species of this genus which is represented by five species in Uttarakhand. 
It blooms during peak rainy season and some insects take shelter inside corolla tube. This species has little aroma in its underground parts and collected commercially for this. In trade they call it ‘Patthar Long’.
However, other species Didymocarpus aromaticus (=D.subalternans) has strong agreeable aroma in aerial parts.
Photographed near Jeolikot, Uttarakhand.

Thank you for sharing ... we (... and I) were very happy when we saw it last month (Aug'13), near Chakrata, on the vertical wall of flowing stream and it was a wonderful scene.

This beautiful rocky herb was shot from near Chakrata in August 2013...
I hope this should be Didymocarpus pedicellatus R. Br.
Please validate.. 
It is D.pedicellatus. It grows over moist moss covered rocks or walls. I do not expect it at the altitude of Chakrata (2000-2400m) rather it is a species reaching up to 1500m hardly. I believe it was growing at lower altitude when you clicked it. It is frequent on way to Naini Tal from Haldwani. I will share few pics from there.
Yes ... this was around at 1700 mts little before chakrata
