 prairies, Zacate Creek ; and on the Rio Grande, Texas. — From New Braunfels, 

 Lindheimer has sent a variety with brighter yellow flowers, and wlth the ovary and 

 young pod pubescent.

Mexico; coll. of 1851; with ripe fruit — Thc lcaflets are rather shorter than 

 Lindheimer's Texan plant. The ripe pods, of a thin, chartaceous texture, are most- 

 ly much constricted between the secds, perfectly smooth, and unarmed, or vcry rare- 

 ly with one or two minute and weak prickles on the margin ; which, as well as the 

 more numerous and usually narrower leaflets, distinguishes it from 



I M. borealis, Grai/, Pl. Fendl. p. 39. Between thc frontiers of Texas and El 

 Paso; coll. of 1851; with ripe fruit. — The specimens are exactly like those of 

 Fendler ; the branches armed with very strong prlcklcs, and the leavcs vcry small ; 

 the margins of the pod also armed with a few large, hooked prickl 



159. M, borealis, var. ? Texana: foliolis 5 -6-jugis oblongis. — Ilills near Aus- 

 tin, May, in flower; and on the western borders of Texas, in frult. Also in the 

 coll. of 1851. — In foliage this is between M. borealis and M. frngrans; but with 

 the pods of the former. I believe the same plant was gathered by Grcgg, ncai 

 Buena Vista and Cadena ; and it is the plant referred to under M, fragrans in Pl 

 Lindh. l. c. as formerly gathered by Mr. Wright in Texas.

 Mountain valleys, 30 or 40 miles east of the Eio Grande, in Southern New Mexico, 

 Sept. ; in fruit. Dr. Gregg also found it near Ojito. — The legumes, which wcre 

 before unknown, are narrowly linear, falcate-incurvcd or sickle-shaped, glabrous or 

 nearly so, an inch to an inch and a half long, less than two lines wide, the margin 

 beset with one or two hooked prickles, or more commonly naked. — Mr. Bentham 



Stroivibocaiipa cinerascens (sp. nov.) : erecta, humllis ; ramulis foliisque Cinereo-pubescentlbus ; pin- 

 nis unijugis ; foliolis oblongis 8-12-jugis ; pedunculo folium Ecquante ; spicisglobosis ; calyce supenie to- 

 mentoso dimidium corolla^ adsequante. — Valley near Azufrora, New Leon, Dr. Gregg, — '^ Shrub 6- 12 

 inches high." The slender thorns longer than the leaves. Leaflcts twice as large as those of S. reptans. 

 Fruit not seen. 



A closely alUed North Mexican species, but well distinguished by having the leaflets as weil as the 

 pmnre reduced to a slngle pair, is characterized by Mr. Bentham as follows: 



" MiiviosA 2yG0PHyLt.A (sp. nov.) : glabra; aculels infrafoliaceis solitariis recurvis ; pinnis foliolisque 

 unijugis, his parvis oblique orbiculatis crassiusculis ; peduncutis folio sublongioribus ; capitulo globoso ; 

 floribus pentameris ; legumine glabro subfalcato acutissimo marginc nudo vel parce aculeato. — La Va- 



Wisl 



Gregg, — Al- 



Iied to M. depauperata ; but perfectly glabrous ; the leaflets rather larger and thicker (from one to one and 

 a quarter of a line long), never more than one pair on each pinna, of which also each leaf has but one 

 pair. The pod, from an inch to an inch and a half long, is reddish and rather glaucous in the dry state, 

 very smooth, ending in a very sharp point. Thc shrub is said to be two or tliree feet high. I havc seen 

 the flowers only in a withered state." Bcnilu In liLL
