The genus Megacarpaca is widely spread in Asia from the 
Caspian Sea to Western China, and from the Altai range 
to the Western Himalaya. It includes some seven 
species, one of which, J/. bifida, Benth., confined to 
Kashmir, and a second, M. polyandra, Benth., now figured, 
occurring both in Kashmir and Kamaon, deviate remark- 
ably in the number and disposition of their stamens from 
the arrangement characteristic of the natural family 
Cruciferae to which the genus belongs. The presence of 
the genus in the Himalaya was first ascertained by 
Dr. H. Falconer, who obtained flowering specimens of 
iM. polyandra in Kashmir in 1838. Specimens, in leaf 
-Novemper, 1917.
