POLYGONACEAE FORTNIGHT 1-14 May 2014: Rheum webbianum from Uttarakhand_DSR_16

[D.S Rawat]

Rheum webbianum Royle is a tall robust herb in alpine zones of Uttarakhand. Known as ‘Archa” it is not common and restricted to rocky slopes often. The petioles are thick and sour which are boiled and grounded to make ‘chutney’ by herdsmen in alpine zones.

It is one of the Himalayan Rhubarbs and underground rootstock is medicinal.

Photographed in Nilkanth Valley near Badrinath, Uttarakhand.

To me it looks more closer to Rheum australe Syn: R. emodi.

This also looks like mine from the area, the red inflorescence bears fruits and not flowers. Perhaps Ritesh ji will be able to resolve.

Please see the mail by Goraya Ji showing R.australe:

It looks different from my plant.

Additionally, in R.australe rachis of inflorescence is densely pubescent (FoC) as also seen in above picture but not in my plant.
