altitudes. Alaska to Calif., N. Mex., Lab., and Greenl. (Elephantella groenlandica 

 Rydb.) — Stems 10 to 40 cm. high, often in clumps; leaves 5 to 15 cm. long, divided 

 into numerous linear or lanceolate lobes; spikes dense, many-flowered; corolla reddish 

 purple, about 1 cm. long. 



A rather conspicuous plant, but soon out of flower. The flowers bear a striking 

 resemblance to an elephant's head, the long beak suggesting the trunk and two of the 

 lower lobes the ears . 



3. Pedicuiaris contorta Benth. Alpine lousewort. Frequent above timber line, 

 especially on rock slides, and occasionally at middle altitudes on moist rocky slopes. 

 B. C. to Calif, and Mont. — Stems 15 to 30 cm. high, in clumps; leaves 6 to 12 cm. 

 long, divided into numerous toothed linear lobes; flowers yellowish white, in dense 

 spike.'^, about 1 cm. long. 



4. Pedicuiaris bracteosa Benth. Indian warrior. Common at nearly all alti- 

 tudes, in moist woods or thickets, in alpine meadows, or on open slopes. B. C. to 

 Calif., Colo., and Alta. (P. montanensis Rydb.) — Stems mostly solitary, 30 to 80 

 cm. high; leaves 10 to 30 cm. long, divided into numerous toothed lanceolate lobes; 

 flowers 1.5 to 2 cm. long, in long spikes. 



Plants with green corollas and others with dull red ones are often found together. 

 The latter form is P. montanensis, but it appears to be only a color form rather than a 



distinct species. 



13. RHINANTHUS L. 



1. Rliinanthus crista-galli L. Yellow rattle. Occasional on the east slope 

 at low altitudes, in marshes or low thickets. Wash, to Colo., Md., and N. S. — Erect 

 annual, 15 to 50 cm. high, nearly glabrous, simple or with few branches above; leaves 

 opposite, lanceolate to linear, toothed, sessile; flowers in leafy spikes; corolla yellow, 

 8 mm. long; calyx enlarging in fruit, about 1.5 cm. long, compressed. 



14. MELAMPYRTJM L. 



1. Melampyriim lineare Lam. Cow-wheat. Frequent on the west slope at low 

 and middle altitudes, usually in thin and rather dry woods. B. C. to Idaho, N. C, 

 and N. S. — Annual, 10 to 30 cm. high, minutely hairy or nearly glabrous, usually 

 with a few slender branches; leaves opposite, 2 to 6 cm. long, lanceolate or lance- 

 linear, entire; flowers solitary in the leaf axils or in short leafy spikes; corolla 8 to 12 

 mm. long, whitish, often tinged with purple, 2-lipped; capsule flat. 



79. PINGUICULACEAE. Butterwort Family. 



Perennial herbs; flowers very irregular; corolla of united petals, 2-lipped, the 

 corolla tube with a slender spur at the base; stamens 2; fruit a many-seeded capsule. 

 Plants submerged in water; leaves scattered along the slender stems, di\dded into 



numerous threadlike lobes; sepals 2 1. TJTRICTJLARIA. 



Plants growing in wet soil; leaves all clustered at the base of the flower stalk, entire; 



sepals 5 2. PINGTJICULA. 



1. TJTRICTJLARIA L. 



1. TJtricuIaria minor L. Yellow bladderwort. Fish Lake, and probably in 

 other lakes of the west slope. B. C. to Calif., N. J., and Greenl. — Leaves bearing 

 small (2 mm. in diameter) bladders; flowers few, in a raceme on a slender stalk; 

 corolla pale yellow, 4 to 6 mm. wide. 



2. PINGTJICULA L. 



1. Pinguicula vulgaris L. Butterwort. Wet soil at low and middle altitudes 

 on the east slope; scarce, but abundant in some localities. Alaska to Wash., Vt., 

 and Greenl.; also in Eur. and Asia.— Leaves elliptic or oval, 2 to 5 cm. long; stem 

 3 to 10 cm. high, 1 -flowered; corolla purple, about 1 cm. wide.
