Botanical Name: Helicteres isora
Common name: East-Indian screw tree, Nut-leaved screw tree
Hindi: Maror phali
East-Indian screw tree is a sub-deciduous shrub or small tree with grey coloured bark. Leaves simple, serrate margin, scabrous above and pubescent beneath. Flowers solitary or in sparse clusters, with red petals turning pale blue when old. Fruits greenish brown, beaked, cylindrical, spirally twisted on ripening. The twisted shape of the fruit is what lends most of it names like screw tree and maror phalli.
