Abstract

Micromorphology of three species of Portulaca was carried out with the help of light microscopy to determine variations within the species which would aid in correct identification of the plants. Epidermal cells are polygonal with sinuous anticlinal walls in all the three species. Length of epidermal cells of P. grandiflora Hook. is higher than P. oleracea Linn. and P. quadrifida Linn. The leaves of P. quadrifida are epistomatic while the remaining species are amphistomatic with paracytic stomata in all the three species. Mean stomatal index and stomatal frequency are more in P. quadrifida while the mean size of stomata (both length and width) is larger in P. grandiflora for both adaxial and abaxial surfaces. Based on the diagnostic features, an artificial indented key is prepared.
