LEGUMINOSZ-PAPILIONACEZ. 197 
II. KIDNEY-BEAN SERIES. 
The Kidney-beans (Fr., Haricots ;\ figs. 149-152) have resupinate 
hermaphrodite flowers. Their slightly concave receptacle is lined by 
a glandular disk which rises up in the centre into a sheath around 
the foot of the gyneeceum. The calyx, inserted on the rim of the 
receptacular cup, is gamosepalous, five-lobed though two-lipped ; the 
upper lip consists of two lobes, united for a good way by their 
superior edges; the lower, of three lobes, at first imbricated in the 
Phaseolus mulitflorus.

bud. The corolla is papilionaceous. The standard is suborbicular, 
first spreading, finally reflexed or slightly twisted, and subsessile 
with two more or less prominent auricles at the base. Its wings 
are oblong or obovate, as long as the standard or longer. The keel 
varies in form and ends in a spirally twisted beak. The ten stamens 
are superposed five to the sepals, five to the petals. They are 
diadelphous ; and the vexillary filament (the only free one) is di- 
lated a little above its insertion, where it often presents a little scale- 
like appendage. The ten anthers are uniform, introrse two-celled 
and of longitudinal dehiscence. The gynzceum consists of a sessile
