Dear All, All those who send photographs of plants for identification should understand that however expert a person is, he cannot definitely come to the correct identity of the plant by just seeing the photograph. Even if he is familiar with that species and has seen it several times live or as herbarium specimens, he can only tentatively point out the possibility of its identity. There may be some characters which are not evident in the photograph which may indicate a different identification. There is also possibility of introduction of exotic species which he may not have seen before. There is also the possibility of two species now treated separately, one from India and another from a foreign country, may by comparative study turn out to be a single species. There are several pitfalls in taxonomic research, if we follow short-cut methods. Therefore please pardon us if we (even if they are experts) suggest different identifications, Therefore one can confirm the identification only by seeing live plants and dissecting under microscope and studying the floral parts and then check the characters with a recent monograph, a revision or a recent detailed morphological study of the species.
