lands, in the mountains, between Santa Fé and Pecos; August, 1847. — Plant a foot 
high. Peduncles 5 or 6 inches long; half the length occupied by the flowers when 
developed: these are one third of an inch long, apparently violet-purple, on very short 
pedicels, and subtended by minute bracts. Calyx campanulate, with short triangular- 
subulate teeth, pubescent with minute dark hairs. Legume (immature) three fourths of 
an inch long, two lines broad, very minutely puberulent with white hairs, multiovulate, 
several-seeded. — Evidently allied to P. flexuosa, Hook., and P. elongata, Hook., perhaps 
too near to the former: but the flowers are larger, the calyx minutely black-haired and 
not sericeous, the legumes apparently membranaceous, and the whole plant almost 
glabrous. a

puberulis. — Bare, rocky hills, Santa Fé ; April to June. — The specimen I possess is in 
fruit only, about 8 inches high, with a slender, flexuous stem. ‘The flowers are said to 
be “ pale purple.” The legumes are three fourths of an inch long, terete, straight or 
slightly incurved, and one fifth of an inch in diameter. In habit and foliage it is much 
like Phaca annua of Geyer, and P. triflora, DC. (which Dr. Gregg has sent from Chi- 
huahua, &c.) ; but the peduncles are larger, and the pods smaller, more chartaceous, and 
much less inflated.
