 the broad margins of the hood produced beyond its acute apex and folded back over the narrow 

 somewhat crisped or erase crest : leaves bipinnately divided, the oblong-oval leaflets acute at each 

 end, half an inch long. 



C. BRANDEGEI, of the mountains of Southern Colorado and in the Wahsatch, and referred to 

 G. Gaseana, is tall and stout (5 feet high), with twice or thrice pinnately divided leaves, the 

 lanceolate leaflets \ to 1 inch long, acute or acuminate : hood not crested, the margins folded back 

 and not projecting beyond the obtuse summit : capsule oblong-obovate, obtuse, retiexed.

3. D. aureola. (Substitute for D. aurea.) Biennial or sometimes of longer 

 duration, very densely pubescent with stellate hairs : stems stout, simple, 2 to 4 

 inches high : leaves crowded at base, the lowermost dead and blackened, spatulate, 

 obtuse, entire, 3 to 6 lines long : raceme dense : flowers bright yellow : pods broadly

Sierra Nevada, in Sierra County (Lemmon), and on Lassen's Peak, Mrs. Austin. The speci-

6*. D. Lemmoni. Caudex stout and much branched : leaves crowded at the 

 summit of the branches, broadly oblanceolate, obtusish or obtuse, 2 to 4 lines long, 

 with long branching hairs on the margins and loosely scattered over the surface : 

 scape (an inch high) and corymbed pedicels pubescent with horizontally spreading 

 hairs : flowers yellow, nearly 2 lines long : pods ovate-lanceolate, beaked with a very 

 short thick style, sparingly hairy, 3 lines long, rather exceeding the pedicels.

2. D. Californica, Watson. Stem simple, 6 inches high or more, rather stout, 

 from a small deep-seated tuber : leaves 2 to 4, thick, on short petioles, ovate to 

 round-reniform, cordate or sometimes cuneate at base, obscurely sinuate-dentate or 

 coarsely and sharply or laciniately toothed, very rarely 3-lobed : petals 4 to 6 lines
