 Chaetodoii foir., not i'ain:ve- Pods erect or ascending, 5-7 mm. long, 

 oblong 6v«l, ^traiyht or rarely concave (very seldom a little arched 

 nnd sharpi o'.nted and laterally flattened), obliquely apiculate or rarely 

 triangular beaked, with central suture a little convex (but not as much 

 i.r, the dors-ai^ rarely at ail sulcate dorsally, usually shaggy-pubescent, 

 rarely less so, rounded at base and filling the slightly inflated calyx, 

 with cross-section nerirly round but a little flattened literally. Flow- 

 ers 7-10 mm. long, white, erect, in dense heads which are about 2-3 

 cm. long and which mostly elongate to spikes in fruit. Banner oval, 

 veined with purple, about 4 mm. long, arched abruptly to erect at tip 

 of c»lyx, with sides rcflexcd about I mm. wide. Wings 4 mm. long, 

 narrowly and obliquely elliptical, a little arched. full3' 2 mm. longer 

 than keel and 2 mm. shorter than banner, about 3 mm. wide. Keel 

 very short, about 1 mm. longer than calyx, about 2 mm. high and 2 

 anm. long, deltoid, purple. Calyx very villous, about 3 mm. long, cara- 

 panulate lo nearly hemispherical in fruit, rounded at base, with the 

 teeth thre.^dlike and about 4 mm. long, Pedicels none. Bracts seta- 

 ceous, about 4 mm. long, with threadlike tips. Peduncles about twice 

 as long as the leaves. Fruiting spikes 2-7 cm. long, often loose at base. 

 Central leaves about 1 dm. long, the upper ones sessile. Leaflets 7-12 

 mm. long, 8-10 pa;rs, laneeolate, to linear-oblong, cuspidate. Stipules 

 subulate, green, produced into long and threadlike tips about 1-1.5 cm. 

 long. Stems slender, many, decumbent. 1-2 feet long, nearly simple, 

 with slender internodes. Pubescence long-villous over the whole 

 plant, especially on the calyx, less dense on the leaves, with hairs sin- 

 uous, very slender and attached by a pustulate base. This species is 

 rather co-nmon on hills and plains of the Columbia Basin to Baker 

 City on the east and Honey Lake on the south, not in the Flathead re- 

 gion. Middle Temperate life zone, in gravelly and clay soil.

 (1902). Pods oval-ovate, about 5 mm. long, 2 mm. wide and 1 nrm. 

 high, notched at base, abruptly rounded at both ends, chartaceous, 

 softly short-villous. spicate. reflexed on a stout pedicel 1 mm. long, 

 with straight dorsal suture and upturned acuminate flat beak about 1 

 mm. long, with longitudinal section half-oblong-oval, with cross-sec- 

 tion oblately deltoid-cordate and pod broadly sulcate to the middle 

 and septum produced nearly to the ventral except at tip. Flowers in 

 a spike 5-7 cm long, reflexed. about 1 cm. long, pinkish, with petals 

 about as long as calyx and teeth. Banner nearly round. 3-4 mm. long, 

 but little arched, about 2 mm. longer than wings, with margins a little 

 reflexed all around. Wings broadly oblong, rounded. 2 mm. wide, 

 about 1 mm. longer than keel. Keel about 3 mm. long and high, the 

 tip rounded to a litte more than a half circle, the upper side about 

 straight, the longitudinal section half-cuneate-obovate. Calyx cam- 

 panulate, 3-4 mm. long and nearly as high, rather truncate below and 

 inserted on the lower corner and sessile in flower, hardly oblique above, 

 with filiform, green, lax lobes nearly twice as long as tube. Bracts 



'filiform-subulate, thin, lax, about 1 cm. long, peduncles rarely 5 cm. 

 long, much shorter than the leaves, and rather shorter than the fruit- 

 ing rachis. Leaves 1-2 dm. long, recurved, narrow and tapering, short-
