* 3. B. MONANDRA Kurz. 
A small or medium-sized tree, the branches long, spreading. Leaves 
11 to 15 em long and wide, cleft about half way to the base, the lobes 
rounded or obtuse, base broadly cordate, 13-nerved. Racemes few-flowered, - 
axillary. Calyx 2.5 cm long, split to the base on one side. Corolla about 
10 cm in diameter, the petals spreading, not at all imbricate, narrowly 
obovate, long-clawed, pink-purple with numerous, small, darker dots, the 
upper petal much darker purple than the others. Stamen 1, as long 
as the style and ovary. Pod stout, thick, about 20 em long, 2.5 to 3 cm 
wide. (FI. Filip. pl. 82, B. subrotundifolia.) 
Cultivated for ornamental purposes, fl. most of the year. Probably a 
native of tropical America, now found in many tropical countries. 
12. DELONIX Rafinesque 
Large unarmed trees, the leaves bipinnate, the leaflets small, numerous. 
Flowers large and showy, red or yellowish, in racemes at the ends of the 
branches forming leafy panicles. Calyx-tube disk-like or shortly turbinate, 
with 5, subequal, valvate segments. Petals 5, spreading, clawed, the limbs 
orbicular, the upper one differing somewhat in shape and involute at the 
base. Stamens 10, free, declinate, villous below. Ovary sessile, many- 
ovuled. Pod large, elongated, woody, compressed, 2-valved, many-seeded. 
Species 3 in tropical Africa and Asia, 1 introduced in the Philippines.

fuego (Sp.-Fil.); Flame Tree, Fire Tree, Flamboyant. 
A deciduous tree reaching a height of 20 m or more, slightly pubescent 
or nearly glabrous. Leaves 20 to 40 cm long, with small, decidous, pinnate 
stipules; pinnae opposite, 15 to 20 pairs, 7 to 15 cm long, leaflets oblong, 
obtuse, 18 to 30 pairs 1 cm long or less. Racemes in the uppermost axils, 
the inflorescence 20 to 40 cm long. Flowers long-pedicelled, red or red and 
yellow, 10 to 12 cm in diameter. Pods pendulous about 50 cm long and 5 
em wide. (FI. Filip. pl. 451.) 
Commonly planted for ornament, fl. March—July; now found in cultiva- 
tion in most large towns in the Philippines, probably introduced about the 
middle of the last century. A native of Madagascar and tropical Africa, 
now cultivated in most tropical countries.
