Wild Plant for ID : Oman : 301212 : AK-2: A small wild plant seen growing on rocks in Muscat, Oman on 12/3/2-10.

Saw lots of buds, but no open flowers.
Any clue to its id?

Polycarpea sp.???????????????

Thanks for a possible id.
On searching, the closest I could come to was Polycarpaea robbairea.
I could find one more picture with a few open flowers.
Hope this picture helps.

This has been identified by … as Polycarpaea spicata.
…, your guess of Polycarpaea was correct.
Probably desert flora in India should be similar.
