\n<\/span>Rheum webbianum<\/b> Royle is a tall robust herb in alpine zones of Uttarakhand. Known as \u2018<\/span>Archa<\/b>\u201d it is not common and restricted to rocky slopes often.
\n<\/span>The petioles are thick and sour which are boiled and grounded to make \u2018chutney\u2019 by herdsmen in alpine zones.
\n<\/span>It is one of the Himalayan Rhubarbs and underground rootstock is medicinal.
\n<\/span>Photographed <\/span>in Nilkanth Valley near Badrinath, Uttarakhand.<\/span><\/div>\n
\n
\n

To me it looks more closer to Rheum australe Syn: R. emodi.<\/i><\/span><\/span><\/span><\/span><\/p>\n

\n

This also looks like mine from the area, the red inflorescence bears fruits and not flowers. Perhaps … will be able to resolve.<\/p>\n

\n

Please see <\/span>the mail by …<\/span><\/a> showing R.australe<\/b><\/i>: <\/span><\/p>\n

It looks different from my plant.
\n<\/span>Additionally, in R.australe<\/i> rachis of inflorescence is densely pubescent (FoC) as also seen in above picture<\/span> but not in my plant.<\/span><\/div>\n

I am also confused as the keys do not give a clear idea.<\/div>\n

Here are focussed distinctly cordate leaves of image 2032<\/p>\n

\n

I think keys with regard to\u00a0base of the leaf<\/b>\u00a0given in Flora of China may not be correct as\u00a0Flora of China<\/a>\u00a0itself says\u00a0leaf blade ovate-elliptic or broadly ovate, large, 20-50 \u00d7 18-40 cm, abaxially pilose, basal veins 5-7,\u00a0base cordate,<\/b>\u00a0margin entire, sinuolate, apex obtuse. Also\u00a0Flora of Pakistan<\/a> supports it.
\n<\/span>This is also clearly evident from our images at\u00a0<\/span>Rheum australe<\/a><\/em>.<\/span><\/p>\n

\n
\n<\/div>\n

I have doubts about the id after going through your images from Kashmir as the fruit perianth colour is whitish (although nothing has been mentioned about it in the efloras) and not purple red\/ red (as mentioned in\u00a0Flora of Pakistan<\/a>\u00a0and\u00a0Flora of China<\/a>) at\u00a0<\/span>
