112 NATURAL HISTORY OF PLANTS. 
matiferous apex is more or less dilated into a terminal or oblique 
head. The pod varies greatly in form, being indehiscent or bivalve, 
with its cavity continuous or divided by false dissepiments of variable 
thickness into as many spurious cells as there are seeds. Within 
the seed-coats is a fleshy embryo surrounded by a variable thickness 
of albumen. 
The Bauhinias constructed on the above described plan have been 
made into seven sections, which some authors have considered distinct 
genera. In Adenolobus,' Pauletia, Perlebia, Pileostigma,' and Schnella® 
the gynzceum is inserted in the bottom of the receptacle, while in 
Amaria’ and Lysiphyllum it is inserted laterally on its wall. The 
species whose androceum always consists in part of sterile stamens 
are comprised in the sections Casparia,’ Loxocalyx, Phanera, and 
Lasiobema. In the first section the only well developed stamen is 
that superposed to the carpel, which is very large (fig. 86), and the 
rest are monadelphous, sterile, or more rarely with from two to four 
fertile towards the posterior side of the flower.’ In Lozocalyz" there

single species of this section the calyx has only 
five teeth, and there are ten stamens. 
2 Cav., Icon., v. 5, t. 409, 410. This section 
contains two-score species from America, and 
eight or nine from tropical Asia and Africa. 
The calyx opens nearly to the base by five clefts, 
or is one cleft in a single piece. The stamens 
are all fertile, or more rarely the five oppositi- 
petalous or the vexillary alone is sterile. The 
leaves are entire or two-lobed on slender un- 
armed or prickly stems. (Jacq., Amer., t. 177;

4 Hocust., in Flora (1846), 528. Calyx of 
Pauletia, often dehiscing by a single vertical 
cleft. Stamens ten, fertile, free or slightly 
monadelphous. Coriaceous or nearly woody, in- 
dehiscent or bivalve at a very late stage. Vege- 
tative characters of Pauletia. Six or seven 
species from tropical Asia and Africa. (Hoox.,

i. 226, t. 60.—Fiztp. & Garpn., Sert. Pl., t. 10.)

Fruit flattened, coriaceous dehiscent, or mem-. 
branous indehiscent. Leaves two-lobed or 2- 
foliolate. Species fifteen, all climbing, lianas, 
with simple racemes, from tropical America.

of unarmed erect trees or shrubs from Mexico 
and the Antilles. Leaves entire or two-lobed.

climbing cirrhose species, with flowers in simple 
or forked racemes, and an elongated coriaceous 
bivalve pod. It comes from tropical Asia (B.
