Trichomes occurring on floral parts in some Indian and African species ofCrotalaria
Structure of the trichomes occurring on floral parts is described in eighteen species ofCrotalaria. On the basis of structure they are classified into 9 types of which ontogeny of four types has been studied. Organographic distribution of each type is given. The four hair types of which ontogeny was studied, all develop from a single initial cell. Most of the hairs can be used for specific delineation although they show less variations. A key for the identification of the species on the basis of the trichomes studied is given.
