POLLEN FLORA OF PAKISTAN-MALVACEAE: DOMBEYOIDEAE-LXII
Abstract
Pollen morphology of 2 species of the subfamily Dombeyoideae from Pakistan has been examined by light and scanning electron microscope. Pollen grains are usually radially symmetrical, isopolar, triporate and sub-oblate to spheroidal. Sexine thinner than nexine. Tectum echinate. On the basis of polar length two distinct pollen types viz., Melhania denhamii-type and Melhania futteyporensis-type are recognized.
