are three fertile stamens; the rest are sterile, and the calyx is re- 
curved ; while the insertion of the gynzceum, central in Casparia, is 
here excentric. Phanera' resembles Lowo- 
calye in the insertion of the pistil; but 
its calyx splits to the base into long straps, 
while it is only shortly five-cleft in the 
former section. In Lasiobema’ the receptacle 
is shallow, and the number of stamens is 
often reduced to five, of which the three 
anterior are alone fertile. The gynaceum, 
which is often pauciovulate, has behind it 
a large gland of variable form. 
Thus constituted’ the genus Bauhinia 
consists of some hundred and _ twenty-five 
species‘ of erect or climbing trees or shrubs 
from all tropical countries. The stem is 
often flattened and deformed,’ and there are 
often simple cirrhi or tendrils at the base 
of the intlorescence. The leaves are simple 
Bauhinia (Casparia) porrecta.

Fertile stamens four or five, the rest sterile or 
altogether absent. Pod coriaceous bivalve. This 
section comprises some forty species from tropi- 
cal Asia and Africa, and from the Cape. Un- 
armed shrubs either sarmentose and cirrhose or 
erect, with entire or two-lobed leaves. (VAluL.,

This section might perhaps be raised to the rank 
of a distinct genus. The flowers have a very 
. shallow receptacle. In ZL. anguinea Grirr., 
the calyx is gamosepalous, five toothed; the 
petals are markedly imbricate, with the vexillary 
internal. There are five stamens, alternipetalous, 
of which the three anterior alone have fertile 
introrse anthers. The two posterior are short 
tongues, which may even be absent. Between 
these two, in the middle line against the pla- 
centary edge of the ovary, is a large projecting 
gland. The stipitate ovary is somewhat excentri- 
cally inserted; it contains two descending ana- 
VOL. II. 
tropous ovules, and ends in a bowed subulate 
style. The fruit is short, flattened, and inde- 
hiscent. Lasiobema consists of cirrhose climbing 
shrubs, with a compressed undulate stem, entire 
and two-lobed leaves, and numerous smull flowers, 
in ramified racemes. Only one species is known 
(Roxz., Pl. Coromandel. t. 285). By the 
above features Lasiobema affords a transition 
between Bauhinia proper and the genera Sin- 
dora and Detariwm of the series Copaiferea.
