326 A FLORA OF MANILA 
2. CEIBA Gaertner 
Trees, with us of medium size. Leaves digitately compound, deciduous. 
Flowers appearing with or before the leaves, fascicled in the upper axils, 
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, 5-celled, 5-valved, 
valves silky within. Seeds globose, smooth, with silky hairs. (A native 
American name.) 
Species 9, probably all originally of tropical America, one now distributed 
throughout the tropics. 
1. C. PENTANDRA (L.) Gaertn. Boboy (Tag.); Silk Cotton Tree, Kapoc. 
Usually a slender erect tree 15 m or less in height, the trunk cylindric 
usually with scattered large spines, the branches in distant worls, spreading 
horizontally. Leaflets 5 to 8, lanceolate, acuminate, entire, 6 to 15 cm long, 
the petioles as long as or longer than the leaflets. Flowers numerous, 
whitish, about 8 cm long. Petals densely silky outside. Capsules oblong, 
pendulous, about 15 cm long and 5 em thick. (FI. Filip. pl. 238.) — 
Scattered throughout our area, fl. Jan—March; widely distributed in the 
Philippines, although not found truly wild; undoubtedly with us an in- 
troduced tree, and probably originating in tropical America. All tropical 
countries. 
86. STERCULIACEAE (CACAO OR CALUMPING FAMILY) 
Herbs, shrubs, or trees, usually pubescent. Leaves alternate, simple

united in a tube, rarely few and free; anthers variously disposed on the 
staminal-tube. Ovary free, 2- to 5-celled, rarely of 1 carpel, sessile or 
stalked; styles connate; ovules few or many, attached in the inner angles of 
the carpels. Fruit dry or fleshy, dehiscent or indehiscent.
