Pollen Morphology in Some Members of Liliaceae.

Pollen of 11 species from 5 genera of the tribe Scilleae, Asphodeleae and Dracaeneae of Liliaceae were examined by light microscope. Detailed pollen morphological characteristics are given for all genera on the basis of the results presented here together with data from the literature. The genera are homogeneous in possessing of single longitudinal aperture (monosulcate) with reticulate Psilate smooth exine, finer differences do exist in the reticulation of the exine between species and populations as seen in U. indica and S. indica. The aperture seen on one side of the pollen grain in tribe Scilleae and in centre of the grain in Asphodeleae and aperture shows wide opening in tribe Dracaeneae.
