Scandent, armed. Leaves bipinnate, no stipules ; pe- 

 tioles armed on the under side. Racemes cauline, axilla-

 Filaments naked. Legume winged on the back. 



Introduced into the Botanic garden at Calcutta from 

 Sumatra where it is held in as much dread as the Kan- 

 tuffu is in Abyssinia. 



TVmwA: scarcely any, but many stout, woody branches 

 climbing up and over trees to a great extent. These are 

 covered with dark brown bark, and armed w^th numer- 

 ous, strong, sharp, recurved prickles, the largest of them 

 are generally in stipulary pairs. Leaves alternate, bipin- 

 nate, from one to two feet long. Pinnce from three to six 

 pair, opposite. Leaflets from six to twelve, short-petio- 

 letted, alternate, oval, entire, smooth on both sides, from 

 one to two inches long. Petioles common, and of the pin- 

 nce armed on the underside with sharp, recurved prickles 

 otherwise smooth and polished like every other young 

 part of the plant. Stipules none, but a brown smooth 

 gland in their place. Racemes very large, compound, or 

 simple, from the naked ligneous branches, or from the 

 axils, or they are terminal. Flowers numerous, drooping, 

 pretty large, of an orange colour tinged w ith pink. Bractes 

 minute, caducous, large before the flowers expand. Calyx 

 subcylindric, the inferior division a little longer, base per- 

 manent. Petals subclavate, the superior one rather larger 

 and more beautifully coloured, all are only a little long- 

 er than the calyx and inserted with the stamina a little 

 above its base. In this species the great length of the ca- 

 lyx prevents the petals from expanding. Filaments ten, 

 alternately a little shorter, ascending, smooth. Anthers
