Abstract

|
Pollen morphological studies using light and scanning electron microscopy were conducted to determined the subsectional boundary and species relationship of 12 species of subsect. Meleuphorbia and related taxa. Based on the sculpturing patterns of pollen grains and UPGMA tree from numerical analyses using 8 quantitative pollen characters 12 species were divided into two types: type I, having microperforate pollen grains in E. epicyparissias, E. inermis, E. pillansii, E. obesa, E. bubalina, E. meloformis, E. nesemanii, and E. jansenvillensis, and type II, having fossulate sculpturing pattern in E. longituberculosa, E. monteiri, E. caput-medusae and E. grantii. The resulting pollen data suggest that the subsect. Meleuphorbia should not be a natural group, but closely related to the species from subsect. Anthacantha and sect. Treisia and sect. Medusea. Thus, the pollen morphological data recommended to combine above taxa as a single taxonomic group.
