Abstract

The pollen grains of 10 species from 9 genera of the family Menispermaceae occurring in the state of Kerala were analysed using light microscopy (LM) and scanning electron microscopy (SEM): Anamirta cocculus (L.) Wight & Arn.,Cissampelos pareira L. var. hirsuta (Buch.-Ham. ex DC.) Forman, Cocculus hirsutus (L.) W.Theob., Cyclea peltata (Lam.) Hook.f. & Thomson, Diploclisia glaucescens (Blume) Diels., Stephania wightii (Arn. ex Wight) Dunn., Tiliacora acuminata (Lam.) Hook.f. & Thomson, Tinospora cordifolia (Willd.) Miers, Tinospora crispa (L.) Miers ex Hook. f. & Thomson.,Fibraurea darshani Udayan & Ravikumar. Pollen grains of menispermaceae family are usually radially symmetric, isopolar and tricolporate. The results revealed five types of pollen based on tectum ornamentation (finely reticulate, coarsely reticulate, reticulate-perforate, reticulate and coarsely perforate). Pollen grains also differ in their shape, aperture features and exine thickness. The study also suggested that each genus has its own distinguishing pollen features.
