from obovate and petiolate to oblanceolate, all acutish, some 

 quite sharply few-toothed, others entire, all very glaucous, 

 stellate-hairy superficially, and with some long bristly but 

 forked hairs on the basal and petiolar parts ; cauline leaves V-z 

 inch long or more, linear, sessile, strongly auricled, either 

 obscurely or quite saliently 3 -toothed at apex, glabrous, 

 glaucous: raceme very few-flowered; flowers small, light- 

 purple : pods iV-i to lYi, inches long, little more than V^ line 

 wide, slightly acuminate, straight, erect or ascending on fili- 

 form pedicels V^ inch long: seeds uniserial, very small, oval, 

 winged only across the summit. 



Collected somewhere in either eastern or southern Oregon 

 " in clefts of rocks," in May, 1883, by W. C. Cusick. The 

 label in U. S. Herb, bears the collector's n. 1124. A cespi- 

 tose species, with all the parts remarkably slender and 

 delicate. 



New Papilionaceae. 



Baptisia oxyphyi<la. Main stem not known, but branches 

 glabrous, wiry, beset closely with sessile trifoliolate leaves 

 subtended by spreading conspicuous and persistent stipules ; 

 leaflets Ij^ inches long, rhomboid, cuneately tapering from 

 below the middle, very acute at apex and ending in an almost 

 spinescent sharp mucro, glabrous and finely reticulate on both 

 faces, but the margins obscurely pilose ; stipules more than V^ 

 inch long, spinescently acuminate above an ovate-lanceolate 

 body : raceme probably solitary, large as that of B. leucophaea, 

 conspicuously bracted, the bracts lance-ovate : calyx-segments 

 exceeding the tube, triangular-subulate, very acute, pilose- 

 ciliate : immature pod oval, long-pointed, pubescent. 



Remarkable ally of B. leucophaea, found on Pearl River, 

 southeastern I^ouisiana, in October, 1901, by Mr. Reginald S. 

 Cocks. The rhombic leaflets and large stipules are so rigid, 

 and end so sharply, as to make the plant appear almost spines-
