Dickore & Klimes only list P.abrotanoides from Ladakh.  However, Stewart listed this plus P.atriplicifolia, commenting that the genus was very common in dry desert conditions and the leaves are most variable even in a single patch.  Hooker suggested that only one variable taxon may be involved.  P.abrotanoides has bipinnatisect leaves Whilst P.atriplicifolia has simple leaves with crenate, serrate or subentire leaves.  The calyx of P.abrotanoides is coverd with long cottony wool. 

The Plant List accept both names.  There are pressed at Kew from Afghanistan which fit with Stewart's description.  He lists collections from Kargil & Hemis, giving an altitudinal upper limit of 3000m.  He described P.abrotanoides as common in Ladakh to 3900m.

My thinking is that the images are of P.abrotanoides but one should look out, particularly at lower elevations in Ladakh (and Pakistan) for P.atriplicifolia.

I have three herbarium collections of P. abrotanoides from Kargil (2900 m), Drass (3100 m) and Khalsi (3000 m) all collected in 1971, match well with above.
