II. KIDNEY-BEAN SEPJES. 



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 gyna3ceum. 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 mullijlorus.

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. 2 The gynaeceuui consists of a sessile
