tapering from base, obtuse, contracted at insertion; whole plant 

 glabrous except lower part of calyx which is shaggy with long 

 flat and jointed hairs, the adjoining bracts have a few scattered 

 hairs at base and the corolla is minutely puberulent; spikes 

 capitate in flower, scarcely denser than racemose in fruit; pods 

 nearly sessile; bracts i to i % inches long, surpassing the 

 flowers, uncolored and not enlarged; fruiting calyx 3 to 4 lines 

 long, the narrowly triangular teeth equal the tube and are 

 glabrous; capsule ovate, half as long as the calyx; corolla 

 yellow, tube almost filiform, 9 lines long, abruptly dilated at 

 apex, the galea is subulate, straight, acute, nearly 2 lines long, 

 surpassing the greatly inflated lower portion (exclusive of the 

 teeth) by ^ a line, whitish teeth of the lower lip oblong about 

 % a line long, lower lip inflated like a pouter pigeon, nearly 3 

 lines wide, 1 }4 lines long; anthers not inclosed in galea fully, 

 t -celled; seed coat loose. This differs from O. campestris 

 Benth. conspicuously in the yellow flowers, and other char- 

 acters. Prattville, Cal., 4500 ft. alt., July 3, 1897. 



Pedicularis albomarginata n. sp. Perennial, tufted, erect 

 from an ascending base, 1 to 2 feet high, rather stout, simple; 

 leaves many, appressed, linear, 3 to 4 inches long, 2 to 3 lines 

 wide, obtuse, margined petiole nearly equaling the blade which 

 tapers into it, blade shallow-crenate and crenatures again ob- 

 scurely crenate, margins white, callous; plants glabrous except 

 the lower leaves, and midrib of some others, pubescence of 

 minute crisped hairs; flowers in oblong heads which are 1 to 2 

 inches long, in fruit 4 to 6 inches long, dense; bracts as long as 

 the calyx tube, 4 lines long, gradually passing into leaves below, 

 crenate, oblong; calyx tube ovate, 2-toothed; corolla 9 lines 

 long, bright pink-purple, galea 2 to 2^ lines wide at the blunt 

 tip which is incurved nearly 90 degrees or a trifle more, tip 

 truncate, apiculate on the lower corner; lower lip 2 to 3 lines 

 shorter, very broad, lobes reflexed, wider than long, rounded, the 

 central one much the largest, fully a line long and three lines 

 wide. This is very close to P. crenulata Bentham but is gla- 

 brous and with lower lip of corolla conspicuously shorter than 

 the upper. Deep Creek, E. Nevada, in Steptoe Valley in low
