Rocky Mountain Flora 259 



silky ; leaflets 7-9, linear or linear-oblanceolatc, 3-4 cm. long, 

 green, but appresscd silky on both sides ; stipules subulate : 

 racemes slender and lax ; bracts lanceolate, short-acuminate, not 

 longer than the buds : pedicels and calyx rather long, hairy : 

 flowers about 8 mm. long: calyx not spurred; lips ovate, the 

 upper slightly shorter : corolla light bluish-purple ; banner broad, 

 somewhat shorter than the wings. 



This species is closely related to L. laxijlonis, but the flowers 

 are smaller and lighter and the calyx is not spurred. It grows at 

 an altitude of about 2000 m. 



Montana: Forks of the Madison, 1897, Rydbcrg & Bcssey, 

 4442 (type in herb. N. Y. Bot. Garden), also 4443a. 



Wvo.ming: La Barge, Uintah Co., 1894, E. Stivetison, ijj 

 (somewhat more hairy than the type). 



Lupinus leucanthus sp. nov. 



Perennial, about 6 dm. high : stem minutely strigose, leafy : 

 petioles about 6 cm. long, almost glabrous ; leaflets 5-7, narrowly 

 oblanccolate, 4-5 cm. long, acute or short-acuminate, glabrous 

 above, sparingly appressed hairy beneath ; stipules subulate : 

 raceme lax ; bracts lanceolate, acuminate, about equalling the 

 pedicels, 6-8 mm. long : pedicels and calyx appressed short- 

 haiiy ; lower lip of the latter linear-lanceolate, about ^ longer 

 than the ovate upper one : corolla white with a brownish spot on 

 the banner ; the latter glabrous and almost equalling the wings. 



This species is nearest related to L. Sclienbcrac, but differs in 

 the larger white flowers and the longer upper lip of the calyx. 

 The type sheet bears the name Lupinus barbigcr Wats., but the 

 plant is not at all related to that species. 



Utah: Springdale, 1894, Marcus E. Jones, j24ge (type in 

 U. S. Nat. Herb.). 



Pachylophus macroglottis sp. nov. 



Acaulescent or nearly so: leaves 8-15 cm. long, tapering 

 into a margined petiole ; blades broadly oblanccolate, acute, sinu- 

 ate-dentate, sparingly puberulent, and villous ciliate on the mar- 

 gins and the veins, very thin : hypanthium very long and slender, 

 12-14 cm. long, sparingly villous or nearly glabrous, gradually 

 widening into a funnelform throat, which at the insertion of the 

 sepals, petals and stamens, is about i cm. in diameter : sepals 

 lanceolate, gradually long-acuminate, about 5 cm. long and much 

 exceeding the broadly obcordate petals, which are about 3.5 cm.
