 white. Calyx cup-shaped, truncate, or obscurely 5-lobed. Petals oblong. 

 Staminal bundles 5, connate at the base, each bearing 2 or 3 sinuous or 

 linear anthers. Ovary ovoid, 5-celled; style cylindric, dilated; stigma ob- 

 scurely 5-lobed. Capsule oblong) coriaceous or woody, ^-celled, 5-valved, 

 valves silky within. Seeds globose, smooth, with silky hairs. (A native

 usually with scattered large spines, the branches in distant worls, spreading 

 horizontally. Leaflets 5 to 8, lanceolate, acuminate, entire, 6 to 16 cm long, 

 the petioles as long as or longer than the leaflets. Flowers numerous, 

 whitish, about 3 cm long. Petals densely silky outside. Capsules oblong, 

 pendulous, about 15 cm long and 5 cm thick. (Fl. Filip. pi. ZS8.)
