 reflexcd brown hairs. Leaflets larger and 

 thicker, sometimes 4' long; pedicels 

 mostly shorter than the nearly orbicular 

 canescent bracts; ovary and pods of the 

 petaliferous flowers pubescent through- 

 out, subterranean fruit less abundantly 

 produced than in F. comosa ; calyx larger.

Twining perennial vines, with pinnately 3-7-foliolate leaves, small stipules and rather 

 large brownish-purple or red flowers, mainly in axillary racemes or panicles. Calyx cam- 

 panulate, somewhat 2-lipped, the 2 lateral teeth very small, the 2 upper united and short, 

 the lower one long and acute. Standard ovate, or orbicular, reflexed. Wings obliquely 

 obovate, adherent to the elongated incurved at length twisted keel. Stamens diadelphous 

 (9 and i); anthers all alike; ovary nearly sessile; ovules oo; style slender. Pod linear, 

 straight or slightly curved, compressed, 2-valved, many-seeded. Rootstocks usually tuberous. 

 [Greek, pear, from the shape of the tubers.]
