Rottlera

Rottlera, a genus of trees of the natural order Euphorbiaceæ, found in India and other parts of tropical Asia. The most important species is Rottlera tinctoria (Roxburgh), subsequently called by Müller Mallotus philippinensis. It is a small tree, the wood of which is only fit for fuel, but its bark is employed for tanning, and the crimson powder which covers the ripe fruit is used for dyeing silk, and also as a purgative and anthelmintic. The R. tetracocca and R. peltata of Roxburgh have also been included in the genus Mallotus by Müller under the names M. albus and M. roxburghianus.
