Eaton, .Manual ed. 7, 380. 1836, makes the surprising state- 

 ment "banner 2-parted,"a character not yet observed in any spe- 

 cies of lupine, so far as I am aware. 



Torrey and Gray, PI. N. A. 1 : 374. [840, placed il not in 

 what was afterward designated the Platycarpos section, but in 

 Lupinus proper, with the cotyledons petioled after germination. 

 They described the calyx as having "the upper lip 2-cleft, 

 shorter than the obscurely 3-toothed lower one." They also say 

 "raceme scarcely longer than the leaves, 8-1 2-flowered. Corolla 

 bright blue," and the leaflets are "obtuse, narrowed at the base." 

 They had examined specimens from "barren argillaceous plains 

 of the Missouri," collected by Lewis, Nuttall, and Dr. James, 

 thereby indicating that they had seen the type material collected 

 by Lewis. 



Watson, Proc. Am. Acad. 8: 539. 1873, adds the new char- 

 acter "bractlets minute," and says the leaflets are "acute or ob- 

 tuse," the first definite mention that they are other than obtuse. 

 In Britton and Brown, Illustrated Flora 2: 270. 1897, they are 

 also given as "obtuse or acute at the apex," and the figure rep- 

 resents them as acute. 



The following description is drawn from my no. 9599, col- 

 lected at Wadsworth, Churchhill county, May 7, 1909: 



About 1 dm. high, with an equal spread, or sometimes one 

 and a half times the height, caulescent, the stem proper about 

 2 cm. long, the branches at first ascending, finally spreading, 

 whole plant except the upper surface of the leaflets hirsute with 

 spreading white hairs: petioles two or three times the length of 

 the blade, with a prominent yellow midrib; leaflets usually 5, 

 oblanceolate-oblong, rounded at the apex, 2 cm. or less in length, 

 up to 7 mm. wide, appressed hirsute beneath, glabrous above, 

 margins ciltate: peduncles very short, rarely as much as 1 cm. 

 long, the inflorescence up to 4 or 5cm., but the whole shorter 

 than the leaves: flowers bright violet-blue fading white 01 pink- 

 ish, 6 mm. long, s mm. deep, distance between apices of banner 

 and wings about 2 mm.: bracts membranous, oblong-lanceofate, 

 5 mm. long, over 1 mm. wide at base, bearded with long hirsute 

 hairs: pedicel barely 2 mm. long, glabrous: calyx tube nearly
