Abstract

---

Pollen grains of 8 species belonging to 3 genera viz., Atelanthera, Arcyosperma and Sisymbrium (Brassicaceae) from Pakistan were studied by light microscope. Pollen grains usually radially symmetrical isopolar, prolate spheroidal, prolate and subprolate, tectum reticulate to granulated. On the basis of number of aperture two distinct pollen types are recognized. Atelanthera pollen type 6 colporate and Sisymbrium pollen type 3-4 colpate. Palynological data has been useful at generic and specific levels.
