Madórus, Rumph. amb. 7. t. 14. f. 1. Bark ash-coloured ; 
young shoots covered by soft woolly down. Leaves decussate, 
broad, wedge-shaped, bearded on the upper side at the base, 
pretty smooth on the upper surface, but clothed with woolly down 
on the under side, 4-6 inches long, and 2-3 broad. Umbels 
sometimes, though rarely, compound, surrounded by several 
involucral scales. Flowers beautiful, a mixture of rose colour 
and purple. Nella jeberoo is the Telinga name of this plant, 
Urku the Sanscrit name, and Aknnea the Bengalese name. The 
milky juice which flows from this plant when wounded is applied 
to various medicinal purposes by the natives; besides which 
they employ the plant itself, and preparations thereof, to cure 
all kinds of fits, epileptic, convulsive, spasmodic, and paralytic, 
as well as poisonous bites and venereal complaints. A fine sort 
of silky flax is prepared from the young shoots in some places. 
A large species of gryllus feed upon the leaves. It is the 
Mador and Mudor plant, from which the late Dr. Duncan, of 
Edinburgh, obtained that singular substance called Mudarine, 
which possesses the property of congealing by heat, and becom- 
ing again fluid on exposure to cold.
