. North American trees : being descriptions and illustrations of the trees growing independently of cultivation in North America, north of Mexico and the West Indies . Trees. 436 The Serviceberries stout, hairy, to 4 cm. long. The flowers are 15 mm. across, in short racemose leafy-based cymes, on slender, .hairy, glandular or smooth pedi- [cels; the calyx-tube is obconic, smooth or nearly so, the lobes are small, sharp-pointed, very woolly on the iimer surface, de- ciduous in fruit; the petals are obovate to orbicular, irregularly toothed or wavy margined; styles smooth. The fruit ripens from August to October, is obovoid- oblong, about 8 to 10 mm. in diameter, often twice as long, yel- low to red; the flesh is thin, dry, pleasantly acidulous; the seeds are relatively large. The fruit was an important food for the Indians, who dried it for winter use. The wood is hard, close-grained, satiny, and pinkish red; its specific gravity is about ; it is made into mallets and tool handles. The fruit differs from tjrpical apples in not being sunken in at the base. Malus Macounii Greene, of British Columbia, is, in our judgment, a form of this species. Malus jusca (Rafinesque) Schneider, an older name, is not certainly Fig. 382. — Oregon Crab Apple. IV. THE SERVICEBERRIES GENUS AMELANCHIER MEDICUS [|BOUT 30 species of Amelanchier, all unarmed trees and shrubs, have been described; they abound in the temperate portions of the northern hemisphere, being most abvmdant, as to species, in North America, where, in addition to the arborescent kinds, about 17 species of shrubs are reported, one of them occurring in the mountains of Mexico. The leaves are simple, entire, or variously toothed, stalked and stipulate. The flowers are perfect, disposed in racemes or rarely solitary, appearing with the leaves; the calyx-tube is bell-shaped, adnate to the ovary, its 5 lobes narrow, re- flexed and persistent; the 5 petals are strap-shaped; the many stamens are inserted
