107. [Cratægus hudsonica] Sarg.
Leaves ovate or slightly obovate, acute, gradually and abruptly narrowed and mostly concave-cuneate at the entire base, sharply and often doubly serrate above with straight or incurved glandular teeth, and frequently slightly divided above the middle into short acute lobes, nearly fully grown when the flowers open at the end of May, and then thin, light yellow-green, smooth and glabrous above with the exception of a few short white scattered hairs on the midrib, and pale and glabrous below, and at maturity thin and firm in texture, glabrous, 2′—2½′ long, and 1½′—1¾′ wide, with a slender yellow midrib, and 5 or 6 pairs of thin primary veins extending obliquely to the point of the lobes; petioles slender, wing-margined above, glandular, at first slightly hairy, becoming glabrous and rose color toward the base, ¾′—1′ in length; leaves at the end of vigorous shoots broad-ovate to suborbicular, full and rounded or broad-cuneate at the wide base, deeply divided into broad lateral lobes, and 2′—3′ long and wide. Flowers about ¾′ in diameter, on long slender pedicels, in broad usually 10—12-flowered glabrous corymbs; calyx-tube narrowly obconic, glabrous, the lobes gradually narrowed from a broad base, acuminate, glandular-serrate often only below the middle, glabrous on the outer surface, slightly hairy on the inner surface; stamens 20; anthers rose color; styles 3—5. Fruit ripening early in September, in few-fruited drooping clusters, subglobose, crimson, pruinose, marked by numerous pale dots, about ⅝′ in diameter; calyx enlarged, with a deep broad cavity, and closely appressed serrate lobes villose on the upper side; flesh thick, yellow, dry and mealy; nutlets 3—5, rounded at base and narrowed and rounded at apex, rounded and sometimes ridged on the back with a high rounded ridge, about 5/16′ long.
A tree, sometimes 20° high, with a tall trunk 8′—10′ in diameter, covered with pale scaly bark, heavy ascending and spreading branches forming a broad open head, and stout ascending glabrous branchlets dark orange color when they first appear and light orange-brown and lustrous during their first winter, and armed with numerous slender straight or slightly curved bright red-brown shining spines 1½′—2′ long; sometimes a broad bush, with numerous stout spreading stems.
Distribution. Rolling hills in the valley of the Hudson River, near Albany, Albany County, New York.
108. [Cratægus coccinioides] Ashe.
Leaves broad-ovate, acute, full and rounded or truncate at base, sharply and often doubly serrate with straight glandular teeth, and divided above the middle into short acute lobes, as they unfold conspicuously plicate, very lustrous, yellow-green, and villose on the lower side of the midrib with a few short pale hairs usually persistent during the season, about half grown when the flowers open early in May, and at maturity thin and firm in texture, rather rigid, dull dark green and smooth on the upper surface, pale on the lower surface, 2½′—3′ long, and 2′—2½′ wide, with a thin pale yellow midrib deeply impressed above and often bright red toward the base after midsummer, and slender primary veins arching to the point of the lobes; turning late in October gradually bright orange and scarlet; petioles glandular on the upper side with minute-stalked dark red glands, at first villose, soon glabrous, often bright red or pink toward the base, ¾′—1′ in length; leaves at the end of vigorous shoots more or less cordate at base and usually 3½′—4′ long and wide. Flowers ¾′ in diameter, in very compact 5—7-flowered glabrous or slightly villose corymbs, with coarsely serrate oblong-obovate acute bracts and bractlets, conspicuously glandular with large bright red glands; calyx-tube broadly obconic, glabrous, the lobes gradually narrowed from a broad base, acute and coarsely glandular-serrate; stamens 20; anthers large, deep rose color; styles 5, surrounded at base by a ring of pale tomentum. Fruit ripening early in October and falling gradually during a month or six weeks, on stout pedicels, in few-fruited compact erect clusters, subglobose, much flattened at the ends, often obscurely angled, dark crimson, very lustrous, marked by numerous large pale dots, ¾′ long, and ⅞′ wide; calyx much enlarged and conspicuous, with spreading or erect lobes bright red on the upper side near the base; flesh thick, firm, subacid, more or less deeply tinged with red; nutlets 5, comparatively small, light-colored, narrow at the ends, acute at apex, rounded at base, rounded and slightly ridged on the back, about ⅓′ long.
A tree, sometimes 20° high, with a stem 8′—10′ in diameter, covered with dark brown scaly bark, stout spreading light gray branches forming a broad handsome head, and stout nearly straight glabrous bright chestnut-brown very lustrous branchlets armed with thick dark reddish purple shining spines 1½′—2′ long.
