9. C. flàva, Ait. (SUMMER HAW.) Tree 15--20° high, somewhat pubescent or glabrous; _leaves wedge-obovate or rhombic-obovate_, narrowed into a glandular petiole, _unequally toothed and somewhat cut_ above the middle, _rather thin_, the teeth _glandular_; styles 4--5; fruit somewhat pear-shaped, yellowish, greenish, or reddish (½´ broad).--Sandy soil, Va. to Mo., and southward. Var. pubéscens, Gray. Downy or villous-pubescent when young; leaves thickish, usually obtuse or rounded at the summit; fruit larger (¾´ broad), scarlet or sometimes yellow.--Va. to Fla. 10. C. parvifòlia, Ait. (DWARF THORN.) Shrub 3--6° high, downy; _leaves thick, obovate-spatulate, crenate-toothed_ (½--1½´ long), almost sessile, the upper surface at length shining; flowers solitary or 2--3 together on _very short peduncles; calyx-lobes as long as the petals_; styles 5; fruit globular or pear-shaped, yellowish.--Sandy soil, N. J. to Fla. and La. 18. AMELÁNCHIER, Medic. JUNE-BERRY. Calyx 5-cleft; lobes downy within. Petals oblong, elongated. Stamens numerous, short. Styles 5, united below. Ovary 5-celled, each cell 2-ovuled, but a projection grows from the back of each and forms a false cartilaginous partition; the berry-like pome thus 10-celled, with one seed in each cell (when all ripen).--Small trees or shrubs, with simple sharply serrated leaves, and white racemose flowers. (_Amelancier_ is the name of A. vulgaris in Savoy.) 1. A. Canadénsis, Torr. & Gray. (SHAD-BUSH. SERVICE-BERRY.) A tree 10--30° high, nearly or soon glabrous; leaves ovate to ovate-oblong, usually somewhat cordate at base, pointed, very sharply serrate, 1--3½´ long; bracts and stipules very long-silky-ciliate; flowers large, in drooping nearly glabrous racemes; petals oblong, 6--8´´ long; fruit on elongated pedicels, globose, crimson or purplish, sweet and edible. (Var. Botryapium, _Torr. & Gray_.)--Dry open woodlands; Newf. to Fla., west to Minn., E. Kan., and La. Fruit ripening in June.--Var. ROTUNDIFÒLIA, Torr. & Gray, appears to be only a broad-leaved form. Var. (?) oblongifòlia, Torr. & Gray. A smaller tree or shrub (6--10° high), the young leaves and racemes densely white-tomentose; leaves oblong or sometimes rather broadly elliptical, acute, mostly rounded at base, finely serrate, 1--2´ long; flowers in denser and shorter racemes; petals 3--4´´ long, oblong-spatulate; fruit similar but more juicy, on shorter pedicels.--Low moist grounds or swampy woods; N. Brunswick to Va., west to Minn. and Mo.--A form of this with broader leaves (broadly elliptical or rounded), often very obtuse at the summit, and rounded, subcordate or acute at base, and usually coarsely toothed, is common from Manitoba to Minn. and Iowa, and is sometimes cultivated for its fruit.
