C. LEPTOCARPA (Benth. in Linncea, 22. p. 528) : glabra, herbacea ; caule erecto 

 -3-pedali); petioli basiglanduloso ; foliolis 4:-6-jugis ovato-lanceolatis acumi- 

 natis ; racemis brevibus paniculatis, infimis folio brevioribus ; florious aureis ; legu- 

 mine attenuato-lineari prgelongo compresso marginato recurvato ! (Ceet. fere C. occi- 

 dentalis.) — Pebbly bed of mountain streamlets, near the San Pedro, Sonora ; Sept. 

 (1032.) — The gland at the base of the petiole is oblong and acute. The leaflets 

 are smaller than is usual in C. occidentalis (from one to barely two inches in length), 

 and the flowers in the dried specimens are much deeper-colored. But the principal 

 character is furnished by the pods, which (even when very immature) are eight inches 

 long, and only a line and a half wide, tapering upwards, and arcuate-recurved, as in 

 C. obtusifolia. E-ipe seeds not seen ; their longer diameter lengthwise in the pod. 

 From the character this must be the C. leptocarpa, which was gathered in Brazil.

 centibus ; legumine lineari plano vernicoso, valvis chartaceis. — Heads of the Agua 

 Prieta, Sonora; Oct. (1033.) — "A much-branched and spreading shrub, 4 to 6 

 feet high." Leaflets often three pairs, 2 or 3 lines long, thickish. Legumes 4 or 5 

 inches long, 3 lines wide, very flat and thin, obtuse or apiculate, somewhat stipitate, 

 many-seeded ; the surface appearing as if covered with a shining varnish. It be- 

 longs to the section Chamaesenna. 



C. (Cham.i;crista) Wrightii (sp. nov.): glabra, humilis ; caulibus assurgentibus 

 plurimis e radice crassa perenni ; stipulis subulatis ; foliolis 4 - 7-jugis lineari-ellip-
