[Gurcharan Singh]

Mimosa himalayana Gamble in Kew Bull. 1920: 4. 1920.

syn: Mimosa rubricaulis sensu auct.; Mimosa rubricaulis subsp. himalayana (Gamble) H.Ohashi

A large deciduous shrub with ribbed densely hairy branches with straight or hooked up to 4 mm long prickles; leaf bippinate with up to 25 cm long rachis; pinnae 5-12 pairs, leaflets (pinnules) 6-15 pairs, 3-8 mm long; flowers pink fading to white in 12-15 mm across heads on up to 6 cm long peduncle, forming panicle; pod up to 10 cm long, 4-10 jointed, glabrous, with few prickles on sutures.

Gurcharan ji,
Thanks for sharing these pictures.
I too have photographed these a little after leaving Jammu.
You could see a number of them along the National highway at a
particular altitude.
Did not find them after climbing higher up to Patni Top.
Regards,
Aarti

Google search gave me a small peep into Jastor Gamble original paper:

Gamble differentiated this species on the basis of 8-12 pairs of pinnae, each pinna with 16-20 pairs of leaflets most commonly 19, and pod acuminate in most cases.
