begonia…?? : .. pertaining only to Kalatope Khajjiar sanctuary around my house from an altitude of 2100 mts to 2500 mts (the area which I have covered)


– Genus Begonia has more than 1500 species, often very difficult to identify.
Once you have told us the place we know we will have to mostly choose between B. picta (leaves often blotched with pink, hairy ; flowers tinged pink and capsule with unequal wings) and B. dioica (syn: B. amoena; leaves green, glabrous, flowers mostly white and capsule with equal wings).
Obviously your plant is B. dioica.

First Begonias are out and in no time the Painted Leaf Begonias will be out too. I am seeing their velvety leaves everywhere. Here I have the Three-petal Begonia, both female and male. I am not absolutely certain about the male (four petals) belonging to the same species and need expert advice. Please confirm.

Begonia dioica

The female has three petals, pronounced pedicel and tuning fork like stamens.


Wonderful photgraphs,

Again looks like B. dioica to me. We have these growing commonly on tree trunks and rock faces. Hairless flowers/buds, pink stems, smooth leaves with toothed edges match the description. We’ll need flowers to be certain. Here are a couple of B. dioica from here.
