some distance to that of the corolla.’ The ovary, tapering above 
into a long slender style, contains a variable number of descending 
ovules, in two rows. The pod is oval or oblong, straight or some- 
what bowed, woody, and indehiscent, with transverse false septa 
separating the seeds. The two known species of the genus Seri- 
anthes are inhabitants of tropical Africa and the Pacific ;? one of 
them is also found in New Caledonia. 
Affonsed has altogether the habit, simply pinnate leaves, and large 
flowers of certain species of Jnga. But its gynzceum consists of a 
number of free carpels (from two to six), each, 
however, being formed as in Jnga, and similarly 
becoming a few- or many-seeded pod. The an- 
droceum and corolla are united for a certain 
distance at the base, and the calyx forms a large 
sac, often vesicular, with five valvate teeth. The 
four known species of this genus‘ are Brazilian 
trees, with paripinnate leaves, possessing per- 
sistent stipules, and sessile or pedicellate racemose 
flowers. 
The flowers of Archidendron’ come very near 
Affonsea in corolla, androceum, and gyneceum. 
This last is composed of from five to fifteen 
carpels ; but the calyx here presents a tubular sac, 
whose mouth is truncate and entire; the pod is 
coriaceous, bowed, irregularly twisted, and finally 
opens into two valves. 4. Vaillantii,’ the only known species, is an 
Australian tree, with bipinnate leaves, and shortly pedicellate flowers 
in axillary umbels. Omitting the form of the calyx, Archidendron 
may then be described as an Affonsea, with decompound leaves and 
the fruit of Pithecolobium.
