Pollen morphology of Barleria L. (Acanthaceae) from India.

摘要

The pollen grain morphology of 19 species and one variety of Barleria L. from India, investigated by Light Microscopy and Scanning Electron Microscopy, is presented. The pollen grains of the species studied are spheroidal or sometimes more or less distinctly three-lobed and tri-brevicolporate; the tectum is reticulate, honey comb like. The genus Barleria has pollen grains of distinct morphology, that appears to be isolated within the family with relatively specific pollen grain morphology. Uniform intrageneric pollen grain morphology also indicates monophyly of the group.
