14. PELTOPHORUM Vogel 
Unarmed trees with abruptly bipinnate leaves and showy yellow flowers 
in. ample terminal and axillary panicles. Calyx deeply cleft, the lobes 
imbricate. Petals oblong or roundish, spreading. Stamens 10, free, decli- 
nate, the filaments with a dense tuft of hairs at the base; anthers uniform. 
Ovary sessile, free, few-ovuled; stigma large, peltate. Pod oblong, flat, 
indehiscent, winged along both sutures. (Greek “shield” and “to bear,” 
from the peltate stigma.) ~ 
Species about 6 in most tropical countries, 1 in the Philippines. 
1. P. inerme (Roxb.) Naves (P. ferruginewm Benth.). 
A tree usually 8 to 15 m high with a dense crown of spreading branches, 
the younger parts and inflorescence brown-tomentose. Leaves 25 to 40 cm 
long; pinnae opposite, 10 to 15 pairs, 5 to 12 cm long; leaflets oblong, 
10 to, 15 pairs, somewhat oblique, obtuse or retuse 10 to 18 mm long. 
Panicles 10 to 20 em long. Calyx brown-tomentose. Petals yellow, obovate, 
about 2 cm long. Pods oblong, 5 to 8 cm long, glabrous, closely long- 
itudinally veined, 1- to 4-seeded. (FI. Filip. pl. 335.) 
Commonly cultivated as a shade-tree, fl. March-April; of local occur- 
rence along the seashore in the Philippines. Ceylon, through Malaya to 
northern Australia. 
15. CASSIA Linnaeus 
Erect trees, shrubs, or herbs. Leaves abruptly pinnate. Flowers 
usually large and showy, in axillary and terminal racemes or panicles. 
Calyx-tube short, the sepals imbricate. Petals 5, subequal. Stamens 10, 
rarely all perfect, 3 to 5 being reduced to staminodes or sometimes absent; 
anthers mostly basifixed, opening by terminal pores or with the slit more 
or less continued downward. Ovary sessile or stalked. Pod very variable, 
terete or flat, dehiscent or indehiscent, usually septate between the seeds.
