In the present investigation leaf anatomy of fifteen epiphytic orchids belonging to nine genera viz., Acampe, Aerides, Bulbophyllum, Cottonia, Dendrobium, Pholidota, Porpax, Rhynchostylis, and Smithsonia from Western Ghats, Goa were studied. The study revealed differences with respect to leaf orientation, leaf texture, leaf surface and stomata. The stomatal types reported were anomocytic, tetracytic, pentacytic and paracytic. Maximum stomatal index was reported in Porpax filiformis while it was found to be minimum in Rhynchostylis retusa. Stomatal frequency ranged between 25 mm2 to 76.25 mm2 .
