flowers from ladakh, mm4 08062011:
Some more flower photographs from the trip to ladakh in july 2008. Wondering
if this flower can identified.
This one was growing near sarchu
The first photograph is a detail from the second
Looks like some Polygonaceae. Probably Koenigia. Could u plz post a closeup of the leaf and inflorescence?
unfortunately this is the only photograph that i have

This is Aconogonon tortuosum var. tibetanum (Polygonaceae) frequently seen in glacial moraines in ladakh

Id pl-Plant of Boraginaceae? genus and sps pl. Plant of Ladakh.
A good close-up but not the Boraginaceae family.
Seems to be Polygonaceae, may be Aconogonum tortuosum (syn. Polygonum tortusoum) but it would help if you have any images of lower down the plant to send. This would help confirm the identification of this very variable shrub? It may be that someone else can immediately recognises I with confidence.
But, as I said for your Lindelofia post, please take and post more than just one photo per plant (several, covering close-ups of flowers and foliage plus habit and of habitat make areal difference; with the advent of good compact digital cameras this can now be done at no cost).  Sometimes a species is distinctive and can be recognised from a single image but not always (and not everyone do this reliably) also do give an altitude and approximate location each time.
Extra images and information provide extra clues.  I approach plant identification as detective work – the more clues and supporting evidence, the better – helping with the reliability and accuracy of naming.  They also reduce the time it takes to “track down” the family, genus or species – it can be very time-consuming attempting to identify a plant from only one or two general images and at times, impossible without such close-up shots of all the plant and location details to check that the species we think a plant is, makes sense from existing records.

Kailash-Manasarovar Yatra::Rhodiola sp ?? NSJ-OCT 16/10 : 5 posts by 3 authors. Attachments (4)
Rhodiola sp ?? for ID photo taken on the banks of Manasarovar, Tibet. Altitude 15000 feet. Aug 25, 2016.

When I saw the suggested genus for this, I was thinking, “Oh no!”, I shall have to be “banging on” about how difficult Rhodiolas are to name but was relieved when it turned out this was not Rhodiola nor any member of the Crassulaceae family but Polygonaceae.
My first impressions are Aconogonum tortuosum– which ‘Flowers of the Himalaya’ say is found on stony slopes in Tibetan borderlands @ 3300-5600m from Afghanistan to Bhutan and Tibet – so this all fits. Stewart knew this as Polygonum tortuosum– a variable ‘shrub’ of the inner ranges but happy to hear of other suggestions.

Thanks, …, for the Id. I think matches with images of the same species at
