Leaf Epidermal Micromorphology ofPortulacaL. Species Found in Vadodara, Gujarat, India

[摘要] Micromorphology of three species ofPortulacawas 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 ofP. grandifloraHook. is higher thanP. oleraceaLinn. andP. quadrifidaLinn. The leaves ofP. quadrifidaare epistomatic while the remaining species are amphistomatic with paracytic stomata in all the three species. Mean stomatal index and stomatal frequency are more inP. quadrifidawhile the mean size of stomata (both length and width) is larger inP. grandiflorafor both adaxial and abaxial surfaces. Based on the diagnostic features, an artificial indented key is prepared.
