Euphorbiaceae herb ID from Hooghly 22/9/12 SK1:
This herb looks somewhat similar to Acalypha indica L. and capsule, though smaller, looks like those of Tragia sp., but it is some other herb growing beside railway tracks.
Species : UNKNOWN
Habit & Habitat : wild herb, height leas than 1 foot
Date : 22/9/12, 1.22 p.m.

Acalypha lanceolata syn. A.indica. for me. There are varieties in this species as I have observed.

I thank … for the id of this species

I call it Claoxylon mercurialis (L.) Thwaites based on Tragia mercurialis L.

Thank you Sir for the accepted name.

Actually it is the freedom of an individual to decide which name is to be adopted.

I would also like to call it as you do, it is the very name I found in Bengal Plants.
