    A Persian-Baluchistan species, not recorded previously from Pakistan. It grows on dry sandy and gravelly soils on the Iran-Baluchistan border areas, and has been collected mainly from the Makran district in SW. Baluchistan. The plant is quite tall, ranging from 25-40 cm in height. The leaf shape and size varies but it seems from the specimens examined, that the radical leaves are longer and the cauline leaves linear and smaller. The plant is not spiny but the older branches are terminally rigid and somewhat pointed.
