J H. BRACHTCARPA (sp. nov.) : glabriuscula, herbacea ; stipulis obovatis ssepe den- 

 tatis caducis ; petiolis ramisque glandulis minimis rariter conspei"sis ; pinnis bijugis 

 cum impari sequilongis ; foliolis 4-5-jugis ellipticis nunc retusis enervibus subtus 

 glandulis depressis nigro-punctatis ; racemo paucifloro ; calycis laciniis lanceolatis 

 nigro-glandulosis ; petalis subconformibus, unguibus eglandulosis ; legumine ovali 

 fere tequilatero stylo recto cuspidato glabrato ad suturas parce glanduloso et hispido- 

 muricato dispermo. — New Mexico, coll. of 1851; the specimens nearly all in 

 fruit. — A species remarkable for its short and broad, nearly equilateral pods, in this 

 respect apparently much like Bentham's H. platycarpa (a species which is not be- 

 fore me) ; but that has from 4 to 6 pairs of pinnae and no glands. Our species has 

 many ascending stems from a lignescent root, slender, leafy to the top, angled, mi- 

 nutely pubescent or nearly glabrous, either glandless, or, like the petioles, with a 

 few scattered and sessile black glands. Leaflets minutely pubescent or glabrate, 

 3 - 5-lines long, the lower surface sprinkled with rather large, flat, and sessile black 

 glands. Flowers no larger than those of H. Drummondii. Petals yellow, with 

 rather long (reddish) slightly pubescent inappendiculate and glandless claws, the 

 vexillum with a few dark glands on the back. Legume 8 or 9 lines long and 4 or 

 5 broad, rounded at the base, not in the least stipitate, the flat sides puberulent or 

 glabrate, sometimes with a few scattered glands like those of the leaves, the sutures 

 beset with scattered stipitate black glands and with rigid setose-muricate projec- 

 tions. 



t H. Drummondii, Torr. Sf Gray, Fl. 1. p. 393. Between Austin and the Rio 

 Grande, Texas. — Stems woody at the base. Stipules scarious, ovate, often denticu- 

 late. Legumes strongly lunate-incurved, minutely muricate when young. 



147. " H. oxYCARPA (sp. nov.): stipulis ovato-acutis integris ; pinnis 3- 5-jugis 

 cum imparl ; foliolis oblongis enervibus eglandulosis ; calycis laciniis obtusiusculis 

 parce glandulosis ; petalis elliptico-oblongis subnudis brevissime stipitatis ; legu- 

 mine falcate acutissimo stipitato-glanduloso." Benth. 3fss. — Calcareous hills and 

 high prairies of the San Felipe and Live Oak Creeks ; July. Also in the collection 

 of 1851. (Near Monterey, Northern Mexico, Gregg, Edwards, and Eaton.) — " Foli- 

 age nearly that of H. falcaria; flowers of H. Drummondii, but with rather narrow- 

 er petals. Pod an inch or more in length, and not above three lines broad." 

 Benth. Stems and petioles villous-pubescent, often with some stipitate glands inter- 

 mixed; low, slender, from a sufi'rutescent base. Ovules 7-9. Legume 4-6- 

 seeded, in some specimens of Wright's recent collection larger (4 lines wide) and 

 less acute, the young ones densely glandular-hispid. 



148. " H. DENsiFLORA (sp. uov.) : stipulis late ovatis ; caule foliisque pubescenti- 

 bus vix glandulosis ; pinnis 3 - 6-jugis cum imparl ; racemo pedunculato per anthe- 

 sin denso subcapitato calycibusque dense pubescentibus et parce glandulosis ; vex- 



illo dense stipitato-glanduloso ungue dilatato ; legumine — Caulis e basi 



perenni nunc humilis, nunc fere pedalis, simplex vel parce ramosus. Folia et sti- 

 puliE H. falcarise. Pedunculus folio ultimo paullo brevior, floribus confertis mag- 

 nitudine H. falcarite. Stamina 10 omnia antherifera. Ovula circa 8." Benth. 3Iss.
