PLANT 121 SMP JUN 09 Lahaul- Spiti : 11 posts by 7 authors. Attachments (3)

Resending again as not identified earlier.
?Appears close to Himalayan Geranium but anther colour different.
Another beauty from Spiti valley.
On way to Key monastery.

This is Flax (Linum usitatissimum). Mostly cultivated in India, for linseed oil – it is the first time I am seeing it growing wild. 

After having first look at the photograph, I was reminded of Linum, but not L. usitatissimum as I had seen it growing. I notice that present plant has perennial habit, ascending branches, much broader petals and staminodes present. This takes me to Linum perenne.

Thanks …
I had forgotten to see again about this beautiful plant.
… Id appears more likely to me. … views might also be true as Linum usitatissimum is cultivated in India. I am wondering how this plant is present in otherwise barren Spiti valley area. The area where I took the picture was also nowhere near human habitat too.

Can it be Linum austriacum?
Please check with this site

I think yes, more probably L. austriacum subsp. collinum

This is L. usitatissimum, an oilseed crop escape. 

I doubt L. usitatissimum which has narrower non-overlapping and lighter coloured petals. L. perenne could be another possible choice.
