 in outline, with short petioles 5-10 mm. long or the upper ones often sessile ; leaflets 7-13, 

 the blades of the lateral ones elliptic, oval-oblong, or linear-oblong, 0.8-2 cm. long, acutish, 

 or sometimes obtuse, apiculate, reflexed, glabrous above, the nerves often turning purplish 

 beneath : peduncles ancipital, 5-10 cm. long : bracts 2-5 mm. long, setaceous : calyx-lobes 

 acute, as long as the tube : corolla white, turning pink, 10-12 mm. long ; standard
