Helicteres isora, sometimes called the Indian screw tree, is a small tree or large shrub found in southern Asia and northern Oceania. It is usually assigned to the family Malvaceae, but it is sometimes assigned to the family Sterculiaceae. The red flowers are pollinated mainly by sunbirds, butterflies, and Hymenoptera. In the 19th century fibers from the bark were used to make rope and sacks, although nowadays the tree is harvested for the fruits and roots which are used in folk medicine.
