Ga. Elghazaly et R. Chaudhary, POLLEN MORPHOLOGY OF SOME SPECIES OF THE GENUS EUPHORBIA-L, Review of palaeobotany and palynology, 78(3-4), 1993, pp. 293-319
The pollen morphology of sixty species of the genus Euphorbia has been
examined with LM and SEM. The genus has been found to be remarkably e
urypalynous. Seven pollen types have been distinguished. A detailed di
agnosis of each pollen type is given. The geographical distribution of
the pollen types is presented, and a putative evolutionary relationsh
ip between pollen types is suggested.
