[C. suborbiculata] (A). Leaves ovate to slightly obovate; fruit crimson, pruinose.107. [C. hudsonica] (A).

105. [Cratægus dilatata] Sarg.
Leaves broad-ovate, acute, truncate, cordate or slightly rounded at the broad base, coarsely and generally doubly and irregularly serrate above with straight teeth tipped with large dark glands, unequally lobed usually with 2 or 3 pairs of acute or acuminate lateral lobes, about one third grown when the flowers open at the end of May, and then light yellow-green, conspicuously plicate, roughened on the upper surface with short stiff white hairs and glabrous on the lower surface, and at maturity smooth and glabrous, dark green above, pale below, 2′—2½′ long, and almost as wide as long, with a slender midrib and 4 or 5 pairs of thin primary veins; petioles slender, somewhat glandular, at first villose, soon glabrous, often dark red toward the base after midsummer, 1′—2′ in length; leaves at the end of vigorous shoots often 4′—5′ long, and frequently rather broader than long. Flowers 1′—1⅛′ in diameter, on slender elongated hairy pedicels, in broad, loose, usually 8—12-flowered slightly villose corymbs, with lanceolate bracts and bractlets glandular like the inner bud-scales with dark red glands; calyx-tube broadly obconic, covered toward the base with matted pale hairs, nearly glabrous above, the lobes broad, acuminate, coarsely glandular with large scattered red glands, glabrous on the outer surface and generally slightly villose on the inner surface; stamens 20; anthers large, rose color; styles usually 5, surrounded at base by small tufts of white hairs. Fruit ripening and falling early in September, on slender pedicels, in many-fruited drooping clusters, subglobose, bright scarlet, marked by numerous small dark dots, about ¾′ in diameter; the calyx much enlarged, with spreading coarsely serrate lobes bright red on the upper side toward the base; flesh thin, sweet and yellow; nutlets 5, thin, rounded and prominently ridged on the back, about ¼′ long.
A tree, occasionally 20° high, with a tall straight trunk, covered with light gray-brown scaly bark, branches spreading into a wide round-topped symmetrical head, and short glabrous slightly zigzag branchlets armed with few stout straight light brown shining spines 1′—2′ long.
Distribution. Eastern Massachusetts, coast of Rhode Island, western Vermont, in the neighborhood of Albany, New York, and near Montreal, Province of Quebec.
106. [Cratægus suborbiculata] Sarg.
Leaves nearly orbicular to oval or rarely to oblong, short-pointed at apex, broad and rounded or broad-cuneate at the entire base, sharply doubly serrate above with slender straight or incurved glandular teeth, and often divided above the middle into 3 or 4 pairs of short acute lobes, when they unfold pale yellow-green and somewhat villose on the upper surface toward the base and below in the axils of the principal veins, about a third grown when the flowers open during the first week of June, and at maturity thin and firm in texture, dull dark green above, paler below, usually about 1½′ long and broad, with a slender midrib and 4 or 5 pairs of thin primary veins; petioles slender, slightly glandular, more or less winged above, ⅝′—1′ in length; leaves at the end of vigorous shoots nearly orbicular to oval, more coarsely serrate and more deeply lobed, and frequently 3′ long and wide, their petioles often broadly winged and conspicuously glandular. Flowers ¾′ in diameter, on short stout pedicels, in compact 6—12-flowered glabrous corymbs; calyx broadly obconic, the lobes gradually narrowed from a broad base, long, acuminate, entire or occasionally obscurely denticulate; stamens 20; anthers small, rose color; styles 5, surrounded at base by a broad ring of hoary tomentum. Fruit falling in October without becoming mellow, on short rigid pedicels, in few-fruited erect clusters, subglobose, often rather longer than broad, about ⅝′ in diameter, dull red more or less blotched with green, or often wholly green on one face, or scarlet in one form; calyx enlarged, prominent, with a broad deep cavity and nearly entire wide-spreading lobes; flesh yellow, thin, dry and hard; nutlets 5, broad and thick, narrow and rounded at the ends, obscurely and unequally grooved on the back, about ¼′ long.
A tree, rarely more than 15°—20° high, with a well-developed trunk 5′—6′ in diameter, stout spreading branches forming a broad low flat-topped head, and stout branchlets orange-brown in their first season, becoming dark gray-brown the following year, and armed with thick straight or slightly curved bright chestnut-brown shining spines 1′—2′ in length.
