STANDLEY FLORA OF GLACIER PARK. 405 



1. Pentstemon confertus Dougl. Yellow beardtongue. Common at low alti- 

 tudes, in moist woods or thickets or on open slopes or prairie; sometimes on slopes or 

 in woods at middle altitudes, and occasionally above timber line. B. C. to Calif., 

 Wyo., and Alta. — Plants glabrous, 15 to 50 cm. high, often forming small clumps; 

 leaves mostly lanceolate, 3 to 10 cm. long, entire; flowers in narrow, long or short 

 panicles; corolla 1 cm. long. 



Unlike most species of the genus, this is a rather inconspicuous plant. The corolla 

 is of a much deeper and brighter yellow when dried than when fresh. 



2. Pentstemon procerus Dougl. In meadows or on prairie at east entrance. B.C. 

 to Calif., Colo., and Sask. — Plants glabrous or nearly so, 15 to 40 cm. high; leaves 4 

 to 8 cm. long, oblanceolate or narrowly or broadly lanceolate, entire; flowers in 

 narrow, short or long, dense panicles; corolla deep purplish blue. 



3. Pentstemon virens Pennell. Blue beardtongue. Frequent at low and 

 middle altitudes, on open slopes or on prairie; occasionally in meadows above timber 

 line. Alta. to Colo, and Nev. — Stems 10 to 30 cm. high, usually tufted; leaves ovate, 

 lanceolate, or oblanceolate, 2 to 5 cm. long, many of them entire; corolla deep blue or 

 purplish blue. 



A very handsome plant, which remains in flower only a short time. It occurs 

 mostly in isolated tufts, never in great abundance. 



4. Pentstemon nitidus Dougl. Occasional on the east slope at low altitudes, on 

 prairie or open hillsides. Wash, to Wyo. and S. Dak.— Stems 20 to 30 cm. high, often 

 in clumps, stout; leaves ovate, lanceolate, or oblanceolate, 3 to 5 cm. long, thick; 

 panicle narrow, with large rounded-ovate bracts; corolla blue. 



The Blackfoot Indians used a decoction of the plant as a remedy for cramps and 

 pains in the stomach. 



5. Pentstemon erianthera Pursh. East entrance, on bluffs, Umbach. Wash, to 

 Nev., Nebr., and N. Dak.^Stems 10 to 30 cm. high, stout, hairy; leaves oblanceolate 

 or linear, 4 to 10 cm. long, finely hairy, usually toothed. 



6. Pentstemon ellipticus Coult. & Fish. Alpine beardtongue. Common above 

 timber line, chiefly on rock slides; occasional at middle altitudes, especially near 

 snow banks or on open rocky slopes. Alta., Mont., and Idaho. — Plants 10 to 20 cm. 

 high, often somewhat woody at the base, forming low broad dense clumps; stems 

 minutely hairy, the calyx with gland-tipped hairs; flowers few, purple, 3 to 3.5 cm. 

 long. 



One of the most showy plants of alpine rock slides, usually covered ^vith large 

 handsome flowers. The plants bloom for a long time. 



7. Pentstemon lyallii A. Gray. Frequent at low and middle altitudes and some- 

 times near timber line, usually on open rocky slopes. B.C., Idaho, Mont., and Alta,. — 

 Stems glabrous or nearly so, usually in dense clumps; leaves finely toothed; corolla 

 3 to 4 cm. long, pale purple. 



A showy plant, with flowers much like those of P. ellipticus. 



8. Pentstemon linearifolius Coult. & Fish. Occasional on the east slope at low 

 and middle altitudes, on open rocky hillsides or shale slides; sometimes on slopes 

 above timber line. Idaho and Mont. — Stems finely hairy, in dense clumps; leaves 

 finely toothed or entire; corolla jDurple to purplish pink. 



Perhaps only a form of P. h/allii; there seems to be no marked difference between 

 the two in size of corolla. One plant collected at Cracker Lake had white flowers. 



5. MIMTJLTJS L. Monkeyflower. 



Plants usually perennial, somewhat succulent; leaves opposite, shallowly toothed; 

 flowers large or small, borne in the leaf axils or arranged in leafy racemes; calyx 

 5-lobed, angled; corolla 2-lipped; stamens 4.
