or absent. The flowers are small and numerous,' in terminal or 
axillary racemes; these are ramified, consisting of a large number 
of regularly or irregularly 
branching cymes,’ and co- Bitiarres Dagee, 
vered with sometimes large 
bracts, and small bractlets, 
either caducous or fairly 
persistent. 
All the plants which in 
common with Dalbergia 
have alternate leaves and 
a dry fruit, with the seeds 
attached by the middle of secre Ba yee 
the inner edge, so that they poe angend 
are neither ascending nor descending, have been united. into a 
separate subseries, which has been named Péerocarpee from the 
included genus Pterocarpus (figs. 188-189), whose fruit is one- 
seeded, suborbicular or oblong, with the edge thinning off into a 
sort of membranous wing. The ten genera of this subseries, 
distinguished from one another by the form of their anthers and 
fruit, are Dalbergia, Ecastaphyllum, Macherium, Cyclolobium, Dre- 
panocarpus, Platypodium, Tipuana, Centrolobium, Pterocarpus, and 
Pecilanthe. 
The six genera Andira, Geoffrea, Coumarouna (fig. 190), Pterodon, 
Euchresta, and Fissicalyx, form the small subseries Andiree or 
Geoffreee in which both the wings and the pieces of the keel are 
free, or rarely united. The ovules are few or solitary ; and the fruit, 
always one-seeded, is usually an indehiscent drupe, or has a thin, 
turgid indehiscent pericarp. 
The single genus Bocoa forms a group apart, possessing the fruit 
of Dalbergia and the allied genera, with a dehiscent pericarp, a sub- 
regular corolla, an irregularly dentate, elongated gamosepalous 
calyx, and alternate leaves. 
In Lonchocarpea, the leaves are compound with the leaflets almost 
constantly opposite. The fruit is not drupaceous but dry and 
1 They are white or more frequently purple into four sections, whose differentiating charac- 
or violet. ters are far from being absolute: 1, Triptolemea;

means of the inflorescence, androceum, and fruit, 4, Selenolobium (BENTH.).
