 terminatin;^^ the stems and branches; pedicels i^''-2'^ long; 

 wings about 2}^'^ long, oval, the outer surface pubescent or 

 puberulent, the margin ciliatc, shorter than the keel which 

 they do not cov^er or conceal; lateral petals much shorter 

 than, often only one-half as long as, the keel; keel mostly 

 uncovered, the most conspicuous part of the flower, 

 3'-4'' long, naked, without crest or beak; stamens ei^rht in 



number; st}'le slender, curved, neither dihated, cucullate nor 

 auriculate, stigma apparently two-lobed and bearded between 

 the lobes which are somewhat separated; mature capsule

This plant was at first taken for P, ovalifoUa, D.C., by 

 Dr. Gray in PI. Lindh., ii. 151, but the distinction between 

 the two is clearly indicated by him in PI. Wright., as above. 



P, ovalifolia, D.C., is not pubescent, but puberulent or 

 almost glabrous, the veins on the under surface of the leaves 

 stand out prominently, the racemes are, in most cases, made 

 up of fewer and more erect flowers, the wings are as long as, 

 or even loncjer than, the keel which they almost conceal, the 

 narrow lateral petals arc almost as long as the keel, and, ac- 

 cording to DcCandolle, the surfaces of the capsule are pube- 

 scent. The only specimens seen by the writer are from 

 Mexico, and, therefore, not within the limits of this paper.
