nearly white outside, the upper surface of the lobes pale-blue-purple, the 
tube constricted above the ovary, then expanded, the limb 8 cm broad, 
spreading. Filaments widened below; anthers bearded. (FI. Filip. pl. 
229.) 
Commonly cultivated in Manila and in many of the larger towns of the

our area. A native of India, now cultivated in many tropical and subtrop- 
ical countries. 
2. T. ALATA Bojer.

in diameter. Capsule depressed-globose, about 8 mm thick, the beak stout, 
about 1 cm long. 
In thickets, occasional, fl. Oct.—-Dec.; local in Luzon, and of recent intro- 
duction, but thoroughly naturalized. A native of Africa, now found in 
India and Malaya. 
3. T. fragrans Roxb. 
A slender, glabrous or nearly glabrous, herbaceous vine reaching a height

the tube slender. Capsule 2 to 2.5 em long, glabrous, shining. 
In thickets Pasay, fl. most of the year; widely distributed in the Philip- 
pines. India to northern Australia.
