nate, sometimes obscurely angled on 



one side nearer the summit than the base. 



sometimcs with the angle produced into a broad tooth or lobe of 2 or 3 lines in 



length. 



Peduncles 4 to 9 inches long, minutely and retrorsely pubescent, florifer- 

 ous above the middle. Bracts minute, subulate, caducous, Calyx 2 lines long, 

 equally S-cleft, or more deeply so between the upper lobes, the narrow and very 

 acute lobes longer than the tube. Vexillum and wings purple in the dried speci- 

 mens, rotund ; the forraer emarginate, 3 or 4 lines, the latter 6 lines long. Carina 

 yellowish, shorter than the vexillum, strongly circinate-incurved, as in P, hetero- 

 phyllus. Ovary minutely pubescent, 6-ovuled. Legume 8 or 9 lines long, 2 lines 

 wide, torulose, incurved. Seeds reniform, smooth. — This species is evidently allied 

 to P. macropus, Benth (which I have not seen), the fruit of wdiich is unknown. It 

 appears to differ in the shape of the leaflets, as well as in their pubescence, which is 

 nearly similar on both surfaces, in the hirsute stems, and in the shape and pubes- 

 cence of the calyx. It should likewise be compared with P. parviflorus, Schlecht 



P. EOTuxDiFOLius (sp. uov. § Microcochle) : perennis, radice tuberosal caulibus 

 decumbentibus cum pedunculis plurifloris folio ter longioribus retrorsum villosis; 

 stipulis ovatis nervosis ; foliolis rotundatis integris utrinque appresso-pubescentibus ; 

 calycibus brevissime pedicellatis villosis, laciniis conformibus subulatis; vexillo alis 

 orbiculatis subsequali ; legumine deflexo lineari-falcato subcompresso 4 - 6-spermo 

 villosissimo. — Valley west of the Chiricahui Mountains, Sonora, in sandy soil; 

 Sept (954.) — Closely related to the preceding species; but the peduncles are 

 hairy like the difl^use and slender stems ; the leaflets are orbicular or rounded- 

 obovate, often retuse (8 to 12 lines in diameter) ; the flowers perhaps rather smaller ; 

 the calyx more hairy ; the wings not so large in proportion to the deeply emargi- 

 nate vexillum, and the ovary and pod very villous, The blossoms have dried of a 



■ 



purple color; but according to Mr. Wrighfs memorandum, they are "deep red."

Galactia tephrodes (sp, nov.) : subvolubilis ; caulibus foliisque pube minuta 

 appressissima sericeo-canescentibus ; foliolis 3 oblongo-lincaribus utrinque obtusissi-. 

 mis mucronulatis ; pcdunculis plurifloris ; calycis lobis oblongis obtusis, postico in- 

 tegro; legumine recto canescente. — Mountain-sides, near Conde's Camp, between the 





copper mines and Chiricahui Mountains, New Mexico ; Aiig. 



(956.) 



Stems nu- 



merous from a lignescent root, 2 or 3 feet long, whitened or cinereous with the very 

 fine and close pubescence. Leafiets less canescent above than beneath, 10 to 16 

 lines long, those of the lower leaves narrowly oblong, of the upper linear, not nar- 

 rowed at the base, often slightly retuse at both ends ; the terminal one rather re- 

 mote from the others. Lower peduncles longer, the upper shorter, than the leaves. 

 Calyx minutely cinereous-pubescent, nearly 3 lines long. Pod 10 to 14 lines long, 

 2 lines wide, 4 - 7-seeded. — The pubescence is nearly as in G. heterophylla, Gray,
