| Abstract: | Pollen morphology of three genera representing 6 species of the family Dipsacaceae from Pakistan has been examined by light and scanning electron microscope. Pollen grains usually radially symmetrical, isopolar, mostly prolate-spheroidal rarely spheroidal, porate or tricolpate, sexine thicker or thinner than nexine. Tectal surface mostly spinulose rarely scabrate. On the basis of apertural types 3 distinct pollen types are recognized, viz.,Dipsacus inermis–type, Pterocephalus gedrosiacus–type and Scabiosa candollei–type. |
