Rubaya Sultan, Afrozah Hassan, Aabid M Rather
Euphorbiaceae flaunt an astonishing range of growth forms, ranging from large desert succulents to trees and even small herbaceous types. Euphorbiaceae is the diverse family with great variability in the pollen structures. The variable structure of pollen grains is necessary for the delimitation of species and hence important for taxonomical purposes. The collected information gives account of the pollen morphology of the various species of Euphorbia. The pollen morphology varies from prolate to spheroidal structures. The presence of colpi is the prominent feature of the family. The foldable pollen structure is necessary for the maintenance of desiccation of pollen grains.
