1. O. indicum (L.) Vent. Pincapincahan, Tagbilao (Tag.). 
A tree 4 to 12 m high with few or no branches. Leaves attaining 1.5 
m in length, 3- or 4-pinnate, the rachis and branches jointed, leaflets nu- 
merous, ovate, acuminate, acute, or obtuse, 5 to 15 cm long. Racemes ter-— 
minal, erect flowering only at the apex, the peduncle and rachis 1 to 3 
m in length. Calyx about 3 cm long. Corolla about 6 to 7 cm long, dark- 
purple, fleshy, bell-shaped, unequal, 5-lobed. Capsule up to 1 m long, 8 
em wide, 1 cm thick or less, flat, slightly curved, margins somewhat incurved

In thickets near Balintauac, fl. July-Nov., and probably in other months; 
widely distributed in the Philippines. India to China and Malaya. 
3. TECOMA Jussieu 
Shrubs or small trees, sometimes scandent, glabrous or somewhat pu- 
bescent. Leaves opposite, simple or simply pinnate, toothed. Racemes or 
panicles terminal. Flowers yellow. Calyx tubular-campanulate, 5-toothed. 
Corolla-tube elongated, straight or incurved, inflated upward, 5-lobed. 
Stamens 4, in 2 pairs. Disk annular. Ovary sessile. Capsule linear or 
elongated, straight or curved, compressed, loculicidally dehiscent. Seeds 
many, the wings thin, hyaline. (From the Mexican name, tecomaxochitl.) 
Species about 80, mostly in tropical America, a single introduced one in 
the Philippines. 
1. T. stans (L.) Juss. 
An erect, branched, sparingly pubescent or nearly glabrous shrub, 2 to 
4mhigh. Leaves opposite, odd-pinnate, up to 20 cm in length; leaflets 5 or 
7, lanceolate to oblong-lanceolate, 6 to 18 em long, long and slenderly acu- 
minate, base acute or acuminate, margins sharply serrate. Panicles ter- 
minal. Flowers racemosely arranged on the few branches. Calyx green, 
5 mm long, 5-toothed. Corolla yellow, 4 to 4.5 em long, tube inflated 
upward. Capsules linear, about 15 cm long, 8 mm wide, acuminate, com- 
pressed. - 
Occasionally cultivated for ornamental purposes, fi. Nov._May; in some 
parts of the Philippines apparently subspontaneous. A native of tropical 
America. 
4. DOLICHANDRONE Seemann 
Glabrous or nearly glabrous trees, with opposite, 1-pinnate leaves. 
Racemes terminal, few-flowered. Calyx closed in bud, in flower cleft to 
the base on one side and spathe-like. Corolla-tube very long, slender, 
narrowly funnel-shaped above, the limb spreading, 5-lobed, the lobes crisped.
