STANDLEY FLORA OF GLACIER PARK. 393 



It makes excellent pies and is still better -when eaten fresh with sugar and cream. 

 The fruit varies greatly in size, shape, and color; in moist woods it is larger, juicier, 

 and more tart, while in exposed places it is small, dryer, and sweeter. Usually it is 

 hemispheric, but frequently it is pear-shaped. Commonly the fruit is purplish black, 

 and often it has a bloom, especially in open places. Some plants bear wine-red fruit 

 which seems to be quite ripe. In autumn the leaves turn deep red. 



4. Vaccinium myrtillus L. Low whortleberry. Frequent at middle altitudes, 

 and also about Belton; usually in deep woods, but occasionally in rather open places. 

 B. C. to N. Mex. and Alta.; also in Eur. {V. oreophilum Rydb.) — Usually about 30 

 cm. high; leaves mostly 1.5 to 2 cm. long, finely toothed, obtuse or acutish; corolla 

 about 4 mm. long; fruit 5 to 8 mm. in diameter. 



The fruit is rather tart and of good flavor, but the plants are so small that it is not 

 easily gathered. The branching in this species is loose and open, and quite unlike 

 the dense broomlike habit of V. scoparium. 



6. Vaccinium scoparium Leiberg. Red whortleberry. Usually about timber 

 line, but sometimes at middle altitudes, on open slopes or in thin or dense woods. 

 B. C. to Calif., N. Mex., and Alta. — Plants usually 20 to 30 cm. high, with dense, 

 mostly erect, broomlike branches; leaves acute, usually 1 to 1.5 cm. long, finely 

 toothed, pale green; corolla 3 mm. long, pink; fruit 4 to 5 mm. in diameter. 



The fruit is of good flavor, but it is too small to be edible. 



67. PRIMTJLACEAE. Primrose Family. 



Annual or perennial herbs; leaves basal, entire or toothed; sepals 4 or 5, partially 

 united; corolla 4 or 5-lobed; stamens as many as the calyx lobes and alternate with 

 them; fruit a 1-celled capsule. 

 Corolla small (3 to 4 mm. long), white, the lobes erect or spreading; stamen.^' distinct, 



included 1. ANDiiOSACE. 



Corolla large (about 10 mm. long), rose-purple, the lobes reflexed; stamens united by 



their anthers, standing above the corolla 2. DODECATHEON. 



1. ANDROSACE L. 



Small annuals; leaves in a basal rosette, entire or toothed; flowers slender-stalked, 

 in umbels. 



Stems glabrous 1. A. subumbellata. 



Stems minutely hairy 2. A. puberulenta. 



1. Androsace subumbellata (A. Nels.) Small. Occasional above timber line, in 

 meadows or on moist rocky slopes. B. C. to Ariz, and N. Mex. — Plants much 

 branched from the base, 4 to 7 cm. high; leaves oblanceolate, 1 to 2 cm. long, acute; 

 umbels short-stalked or sessile; corolla 3 to 4 mm. long. 



2. Androsace puberulenta Rydb. Frequent on the east slope at low altitudes, 

 in low meadows or on dry rocky slopes. Yukon to Ariz, and N. Mex. — Plants 

 5 to 20 cm. high, with numerous flower stems; leaves oblanceolate, 1 to 3 cm. long; 

 umbels long-stalked; corolla about as long as the calyx. 



2. DODECATHEON L. 



Perennials; leaves in basal rosettes, entire or nearly so; flowers in long-stalked 

 umbels, nodding; capsule cyLindric. 



Leaves finely pubescent 1. D. cusickii. 



Leaves glabrous 2. D. pauciflorum . 



1. Dodecatheon cusickii Greene. East entrance, Mrs. Otto Thompson. B. C. and 

 Wash, to Mont, and Alta. — Leaves 3 to 7 cm. long, oblong or oblanceolate, obtuse; 

 flowers few, purple, with yellow throat; capsule 8 mm. long.
