 larger and more veiny leaves, ovoid corolla, and large edible Idue berries. — ll(j(jk 

 1. c. t. 127. 



Common in Oregon, and extending to Lake Superior ; commonly associated with V. parvi- 

 folium, and therefore probably reaching the northern part of the State on the coast. 



3. V. Myrtillus, Linn. Low undershrub, glabrous, with sharply angled green 

 branchlets : leaves ovate or oval, bright green and usually shining, veiny, serrate, 

 very short-petioled : border of the calyx almost entire : corolla between globular 

 and campanulate, 5-toothed, sometimes 4-toothed : stamens 10 or 8: berries blue-

Var. microphyllum, Hook., with clustered stems only a span or less in height : 

 leaves from the sixth to barely half an inch long : flowers only about 2 lines long : 

 berries according to AVatson (Bot. King Exp. 210) light red. But in the Rocky 

 Mountains and in Oregon the berries are dark-colored, and the parts all larger, yet 

 not equalling the European Bilberry in size of foliage, fruit, &c. 



Wet places in the Sierra Nevada, at 7,000 feet (Mariposa Co., Oraij), thence northward, and 

 eastward at high elevations. 



-f- -i- Floiuers 2 or 3 or solitary from a seixirate scahj hud, short -ped uncled. 



4. V. OCCidentale, Gray. Low shrub, glabrous : leaves thinnish, dull and

 leaves conspicuously reticulated beneath, shorter and broader corolla, and berries much larger. 



* % Leaves evergreen and coriaceous : parts of flower in fives and the stamens 1 : 

 anthers not atoned on the hack. 



5. V. ovatum, Pursh. Shrub erect, 3 to 5 feet high, with numerous spreading 

 branches and hirsute branchlets : leaves thick, very smooth, sliining above, ovate 

 varying to oblong-lanceolate, acute, serrate with rigid small teetli, short-petioled : 

 flowers crowded in very short and numerous axillary and terminal racemes : corolla 

 campanulate, pink : calyx-teeth as long as the 5-celled ovary : berries dark purple 

 turning black, without a bloom. — LindL Bot. Iveg. t. 1354. V. lanceolatum, DC,

 teeth recurved. Stamens' 10, included : anthers flattened, furnished with a pair of 

 reflexed awns on the back below the summit ; the cells opening by a terminal pore. 

 Ovary raised on a hypogynous disk, 5-celled : ovules numerous on a flesliy placentti 

 projecting from the inner angle of each cell. Style rather long : stigma obtuse. 

 Berry with a rough or granular surface, maturing several seetls in each cell. — 

 Small trees or shrubs, with evergreen and coriaceous alternate leaves, and white or
