leaflets linear-oblong, acute at each end, 6 to 12 lines long; stipules usu- 

 ally equalling the petiole, 1 to 3 lines long: flowers few, iu short close 

 racemes; bracts very broadly ovate and concave, abruptly acuminate : 

 •calyx 4 lines long, nearly equalling the petals, the long-acuminate lobes 

 exceeding the tube. — Collected by J. Reverchon iu 1877 on rocky 

 prairies in Hood and Johnson Counties, western Texas, and distributed 

 in Curtiss's sets as P. cyphocaJyx, — from which it differs in its shorter 

 leaves and petioles, shorter racemes, much broader bracts, and more 

 deeply lobed calyx, etc. 



Eysenhardtia spinosa, Engelm. Fruiting specimens collected 

 by Pringle (n. 358) on hills near Chihuahua permit a more complete 

 description of this remarkable species, previously found only by Wis- 

 lizenus near Lake Encenillas in the same region. The leaflets are 

 mostly retuse, puberulent beneath : flowers yellowish, the banner 

 emarginate : ovary glabrous, the style very slightly pubescent ; pod 

 inequilaterally ovate in outline, 1 -seeded, 2 lines long, the coriaceous 

 convex valves strongly 2-3-nerved. 



Dalea viridiflora. Decumbently branching at the woody base, 

 the hei'baceous stems 6 inches high, glabrous throughout : leaves an 

 inch long or less ; leaflets small, 4 to 8 pairs, oblong-obovate, obtuse 

 or retuse ; stipules linear-setaceous : spikes sessile or shortly pedun- 

 culate, ovate to cylindrical, J to l.j inches long ; bracts lanceolate, nar- 

 rowed at base, equalling the glabrous shining thin-scarious 10-nerved 

 calyx, with very short acutely trifid teeth (pubescent on the inside) 

 and large glands between the nerves ; petals yellowish green, half 

 longer than the calyx : style slightly villous ; pod glabrous. — Sum- 

 mit of the Santa Eulalia Mountains, Chihuahua ; C. G. Pringle, 

 November, 1885 (n. 518). 



Dalea pldmosa. Sufliuitescent, the slender ascending stems 

 branching above, finely pubescent and dotted with minute black glands, 

 a foot high : leaves an inch long or less ; leaflets 5 to 8 pairs, oblong- 

 obovate, obtuse or retuse, 2 or 3 lines long, somewhat soft-pubescent ; 

 stipules brown, lanceolate : spikes pedunculate, an inch long ; bracts 

 ovate-lanceolate, glabrous, exceeding the calyx-tube, deciduous : calyx- 

 tube campanulate, glabrous, thin, 10-nerved, with 2 to 4 black glands 

 in the intervals, the long filiform teeth and inner margin plumose with 

 long hairs ; petals yellow becoming brownish, the keel 4 lines long : 

 pod villous, short. — In the shade of cliffs near Chihuahua; C. G. 

 Pringle, October, 1885 (n. G21). 



Petalostemon Sabinalis. Perennial, the herbaceous simple 

 stems a foot high, glabrous throughout : leaves yellowish green ;
