Description | ||||||
The taxonomic descriptions and pollen morphology of 4 species belonging to 4 genera of family Euphorbiaceae were described in the present paper. The studied materials were collected throughout Mandalay Region. The plants were identified and their pollen have been examined under microscope. In the present study 4 species have been described together with the taxonomic descriptions and colourphotograph of inflorescence. Pollen morphology and pollen keys to the species were also constructed. In Ricinus communis, the outline of a pollen grain seen in polar view (amb) is rounded triangular and in equatorial view it was observed that suboblate. The remaining 3 species are spheroidal. The exine sculpture of 4 species were pilate, distinctly reticulate and croton pattern. The number of apertures possessed by the pollen grains of 4 species were tricolporate, polyporate and inaperturate. The studied pollen grains are observed in 2 sizes, medium (25-50µ) and large (above 50µ). |
