Taken at Muscat, Oman….first two pictures on the 8th of Feb, 2008 and other two on the 22nd of Feb, 2008.
Bushes found growing in the sand.
… had identified similar bushes from Rajasthan if I am not wrong, but those had no flowers/pods. They were only bushes.

Calligonum polygonoides
Family: Polygonaceae

Other plant was most probably Capparis decidua. This is a true representation of desert flora.

I think I have found the correct id of this bush from Oman.
Had borrowed a book recently ‘Wild Plants of Oman’ by Helen Pickering & Annette Palzelt.
This seems to be Calligonum comosum, common name Fire Bush.
Kindly validate.

many thanks … for sending me such a beautiful photograph of desert plants
I am in Jharkhand and without any literature
yes this is Calligonum speceis
I remember … show me one of fruit photograph when we were in WII and i told him about the genus Calligonum but not sure about the species because
you can check in following link in Flora of Pakisthan

This species is sometimes treated as a subspecies of Calligonum polygonoides L. but can easily be differentiated from the latter by having smaller leaves, larger nuts and pedicel mostly shorter or sometimes equalling the perianth lobes.
