ends, nearly entire, dull, very short-petioled, pale beneath : calyx 5-lobed : corolla 

 globular, 5-toothed: stamens 10: berries pale red, insipid. — Hook. Fl. ii. 33, t. 128. 



Redwoods, &c, Mendocino Co., Bolandcr. Common from Oregon to Sitka. Leaves from a 

 third to a lull inch long. 



2. V. ovalifolium, Smith. A more straggling shrub, with terete branches, 

 larger ami more veiny leaves, ovoid corolla, and large edible blue berries. — Hook. 

 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- 

 black when ripe. — Our plant is wholly the 



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

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

 berries according to Watson (Lot. 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 Lilberry in size of foliage, fruit, &c. 



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

 eastward at high elevations. 



+- +■ Flowers 2 or 3 or solitary from a separate seal// bud, short-peduncled. 



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

 pale both sides, from oval to obovate-oblong or oblanceolate, entire, acutish or 

 obi use, rather obscurely veiny (half to three fourths of an inch long) : flower mostly 

 solitary : lobes of calyx and of the oblong-ovate corolla 4 : berry small, 2 or 3 lines 

 in diameter, blue with a bloom, sweetish.

V. ULlGlNOStrjf, Linn., the Bilberry of Europe, &c., from Oregon northward, has rounder 

 mspicuonsly reticulated beneath, shorter and broader curulla, and berries much larger. 



* * Leaves evergreen and coriaceous : parts of flower in fives and the stamens 10: 

 anthers not aimed on the bach. 



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

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

 varying to oblong-lanceolate, acute, serrate with rigid small teeth, 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. Dot. Reg. t. 1354. V. lanceolalum, DC,

teeth recurved. Sta ns 10, included : anthers flattened, furnished with a pair of 



refiexed awns on the back belo\i the summil : the cells opening by a terminal pore.

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

 Berry with a rough or granular surface, maturing several seeds in each coll —
