late flattened subdehiscent pod, containing one or two seeds, in 
which a thin layer of albumen surrounds the fleshy embryo. B. 
syringafolia F. Muxut., the only species of this genus, is an unarmed 
tree from tropical Australia, whose pinnate leaves are reduced to a 
single large leaflet, accompanied by two little lateral stipules. The 
inflorescence is the same as in Pterolobium. 
It has only been with some hesitation that the two following 
genera, Gleditschia and G'ymnocladus, have been placed in this series ; 
they are closely allied to each other, and agree in having the petals 
of variable number and of nearly the colours and consistency of the 
sepals, by which they are usually very incompletely covered in the 
bud. 
Gymnocladus' has a nearly regular perianth, inserted on the 
mouth of the elongated tubular receptacle, which is lined with 
glandular tissue. There are five sepals, valvate or slightly imbri- 
cated in the bud. The petals are four or five in number, also 
imbricated in the bud. There may be ten stamens inserted on 
the rim of the receptacle, of which five, 
larger than the rest, are superposed to the 
sepals. Their anthers, sterile in the female 
flowers, are well-developed, introrse two- 
celled, and of longitudinal dehiscence in the 
male and hermaphrodite. The gyneceum, 
reduced in the male flowers to a little sterile = Fre. 52. Fie. 53. 
conical body, is inserted in the bottom of 58 ()- Bek Lie aa 
the receptacular tube ; it consists of a sessile 
ovary tapering above into a style, whose ventral angle is traversed 
by a longitudinal groove. The broad lips of this groove separate 
above and become reflexed and covered with stigmatic papille. 
The placenta, superposed to the posterior petal, bears several in- 
completely campylotropous ovules with their micropyles superior. 
The fruit is a pod, whose hard flattened pericarp finally opens in 
two valves. Inside is a fleshy pulp’ surrounding the obovate seeds 
which have pretty long funicles. Hach seed contains a fleshy embryo 
surrounded by horny albumen (figs. 52, 53).°
