Abstract :
To better understand systematic characters of Aconogonon (Polygonaceae), we studiedpollen morphology in three (A. alpinum, A. rumicifolium and A. tortuosum) of five species distributedin Pakistan using light microscopy and scanning electron microscopy. Results showed thatAconogonon is characterized by tricolpate pollen with microspinulose type of exine ornamentation.One distinctive pollen type was recognized on the basis of aperture number and sculpturing of exine under SEM. Based on analyses in the present study, diagnostic keys to the three species were provided.
