STANDLEY FLORA OF GLACIER PARK. 313 



4. Vagnera racemosa (L.) Morong. Occasional at low and middle altitudes, in 

 moist woods or thickets. B. C. to Colo., Ga., and N. S. (Smiladna racemosa Deaf.)— 

 Plants 30 to 60 cm. high, finely hairy; leaves ovate or lanceolate, 6 to 12 cm. long, 

 green; petals 2 mm. long; fruit similar to that of V. amplexicaulis. 



11. STREPTOPTJS Michx. 



1. Streptopus amplexifolius (L.) DC. Twisted-stalk. Common everywhere in 

 moist or wet woods or thickets; frequent about bushes above timber line. Alaska to 

 Oreg., N. Mex., N. C, and Greenl.; also in Eur.— Plants glabrous, 30 to 100 cm. high, 

 from rootstocks; stems branched; leaves ovate, 5 to 12 cm. long, clasping, con- 

 spicuously parallel-veined; petals 8 to 12 mm. long, greenish white, with spreading 

 tips; fruit bright red, oval, 1 to 1.5 cm. long. 



When in flower the plant is not conspicuous, but when loaded with the handsome 

 fruit it is very striking. The fruits are pendent below the leaves on slender stalks, 

 and they are most conspicuous on slopes above the trails, where they are not hidden 

 by the leaves. The slender flower stalks are abruptly bent, hence the name " twisted- 

 etalk." The stems are commonly branched, but plants above timber line frequently 

 have simple stems. The fruit is insipid and inedible. The leaves turn pale yellow 



in autumn. ^ ,. , -r, 



12. DISPORUM Salisb. Fairybells. 



Plants branched, vnih. rootstocks, ' finely hairy; leaves ovate-lanceolate to oval, 

 sharp-pointed, 3 to 10 cm. long, conspicuously parallel- veined , sessile or clasping; 

 flowers yellowish white, 1 to 1.5 cm. long; fruit juicy. 

 Fruit usually broader than long, somewhat lobed, roughened with fine wartlike 



projections; stigma 3-parted 1- D. trachycarpum. 



Fruit longer than broad, not lobed, narrowed to each end, smooth; stigma not parted. 



2. D. oreganum. 



1. Disporum trachycarpum S. Wats. Rough fairybells. Common in moist or 

 wet woods and thickets at low and middle altitudes. B. C. to Man., N. Mex., and 

 Ariz.— Plants 30 to 60 cm. high, mth few branches; fruit about 1 cm. thick. 



The fruit is short-stalked and hidden beneath the leaves; at first it is yellow but it 

 30on turns orange and then deep red. WTien ripe it is very handsome, with a velvety 

 appearance, and suggests a strawberry. 



2. Disporum oreganum (S. Wats.) W. Mill. Smooth fairybells. Frequent in 

 the same situations as the last species. ■ B. C. to Calif, and Mont.— Much like the last 

 species except in form of fruit, the two usually growing together and equally common; 

 fruit about 1 cm. long, usually somewhat sluning, turning lemon-yellow and finally 

 orange-red. . . . 



The fruit is scarcely as handsome as that of D. trachycarpum. In both species it is 



nearly flavorless. 



13. CALOCHORTUS Pursh. 



1. Calochortus elegans Lindl. Mariposa lily. Frequent on open slopes, in 

 meadows, or sometimes in woods, at nearly all elevations. Wash, to Calif., Utah, 

 and Mont.— Plants glabrous, 10 to 20 cm. high, from bulbs; leaf one, 10 to 20 cm. 

 long, 2 to 10 mm. wide; petals 12 to 20 mm. long and nearly as broad, much larger 

 than the sepals, with a gland inside near the base; fruit a 3-angled capsule about 

 2 cm. long. 



The flowers open early in the season and do not last long. The plants are usually 

 scattered among grasses, and the delicate flowers suggest butterflies hovering over 

 the meadows, a fact which doubtless suggested to the Spanish settlers of California 

 the name ' mariposa" (the Spanish word for butterfly). The species of Calochortus 

 are most abundant on the Pacific coast; many of them are in cultivation.
