Dear Dr. Gurcharan Singh Ji,
It is a woody shrub. The height varies from 2' to around 3.5'. The
flowers are in clusters. The fruits in clusters is evidence of that.
Prickles are present both on the stem as well as on the leaves. The
prickles are small ranging from 3 mm in length to around 8 mm in
length, they are thin and very sharp. Towards the tip of the tender
shoot, the prickles are small and dense, however along the rest of the
stem, they are between 18 mm apart to around 30 mm apart. Flowers
definitely occur in clusters, however there are a few flowers that
stand out in singles and twos.
Regards.
Yazdy.
