Louisiana, and Arkansas ; fl. March to June. Var. humillima, Chodat, 1. c. 200, is merely 

 the most dwarf form (or perhaps state) with inflorescences subsessile among tlie radical 

 leaves. 



= = Wings ovate-oblong or elliptic-oblong with short sharp apical cusp : keel with a short 

 crest : stems (mostly 8 inches to a foot or more in height) leafy. 



P. lutea, L. Annual, erect, 6 to 15 inches high: stems often several from a subfibrous 

 root, simple or with a few spreading branches near or above the middle : cauline leaves ob- 

 long-lanceolate, acute ; the lower and radical ones passing to spatulate or even obovate- 

 cuneate with rounded apex : flowers in broad dense obtuse or (through the projecting 

 innermost bracts) cuspidate loug-peduncled capitate racemes, sulphur yellow or oranoe not 

 turning dark in drying ; wings becoming 3^ lines in length and \^ lines in breadth : crest of 

 the keel of 6 or 8 short processes (half line or less in length), the upper (dorsal) ones rather 



broad and not filiform : seed with a slender caruncle most often of nearly its own length.

P. Rugelii, Shuttl. In technical characters very close to the preceding : taller, a foot or 

 two in height : stems simple or with a few simple mostly erect branches : inflorescence ovoid 

 becoming oblong: flowers somewhat larger (wings becoming fully 2 lines in breadth), 

 lemon yellow, turning dark Iduish green in drying : crest of the keel a little over half line 

 in length, the processes subfiliform, often bifld : seeds essentially as in the last. — Shuttl. iu

P. cymosa, Walt. Root a fascicle of long slender flbres : stems single, erect, large, fistu- 

 lose, 1 to 3 feet or more in height : radical leaves linear, attenuate, 3 to 6 inches long, yel- 

 lowish green : racemes at first dense but soon somewhat lax : flowers rather small, yellow 

 becoming greenish black in drying : wings abruptly cuspidate from an obtuse or rounded

P. ramosa, Fll. Fibrous-rooted annual, 8 to 15 inches in height: stem not enlarged he- 

 low, in most specimens equably leafy to the inflorescence : leaves half inch to inch and a 

 half in length ; the cauline oblong, acute ; radical spatulate, obtuse : flowers slender-pedi- 

 celled, in size .and arrangement much as in the last preceding species, also yellow and turn- 

 ing green or black in drying : wings more gradually acuminate : seed small, dark brown, 

 soft-puberulent, and with a minute bifid terminal caruncle. — Sk. ii. 186; Chapm. Fl. 82;
