94. [Cratægus neo-londinensis] Sarg.
Leaves ovate, acute or acuminate, rounded, truncate or broadly concave-cuneate at the wide entire or glandular base, sharply often doubly serrate above with straight glandular teeth, and divided into numerous short narrow acuminate lateral lobes, about half grown when the flowers open the middle of May and then very thin, light yellow-green and roughened above by short white rigid hairs and paler and sparingly hairy below, and at maturity membranaceous, dull yellow-green and scabrate on the upper surface, pale green and glabrous below, or occasionally slightly hairy on the under side of the stout yellow midrib, and of the thin remote primary veins arching to the point of the lobes, 3′—4′ long, and 2½′—3½′ wide; petioles slender, nearly terete, glandular, at first slightly hairy, becoming glabrous and purplish toward the base, 1′—2′ in length; leaves at the end of vigorous shoots only slightly larger. Flowers 1′—1⅛′ in diameter, on slender sparingly villose pedicels, in lax slightly drooping usually 5—12-flowered villose or nearly glabrous corymbs, with linear often slightly falcate glandular bracts and bractlets, persistent until after the flowers open; calyx-tube narrowly obconic, covered with short matted pale hairs, the lobes gradually narrowed from a broad base, acuminate, coarsely glandular-serrate below the middle, glabrous on the outer, villose on the inner surface; stamens 17—21, usually 20; anthers deep rose-purple; styles 4 or 5, usually 5, surrounded at base by a narrow ring of pale tomentum. Fruit ripening and beginning to fall early in September, on stout villose or glabrous pedicels, in large drooping few-fruited clusters, obovoid or short-oblong, bright red, often slightly pruinose, marked by numerous minute pale dots, ⅝′—¾′ long, ½′—⅝′ in diameter; calyx enlarged, prominent, with spreading or erect and incurved coarsely serrate persistent lobes, their upper surface bright red below the middle and covered above with soft white hairs; flesh thick, orange-yellow, soft, juicy and acidulous; nutlets 4 or 5, thin, narrowed at the ends, acute at base, rounded at apex, rounded and sometimes broadly grooved on the back, about 5/16′ long.
A tree, often 20° high, with a tall trunk 8′—10′ in diameter, covered with light grayish brown slightly fissured bark, large spreading and drooping branches forming an open head often 20° across, and slender branchlets olive-green and slightly hairy when they first appear, dull red-brown and marked by many large pale lenticels during their first season, becoming light gray and rather lustrous, and armed with stout straight dark purple shining ultimately gray spines often 2′ long.
Distribution. Borders of woods near the shores of Fisher’s Island Sound, Mumford’s Point, Groton, and near Lyme, New London County, Connecticut.
95. [Cratægus Hillii] Sarg.
Leaves oblong-ovate, acuminate, rounded or rarely cuneate at the broad entire base, coarsely doubly serrate above with straight glandular teeth, and divided into numerous short acuminate lateral lobes, when they unfold coated above with short lustrous white hairs and densely tomentose below, particularly on the midrib and veins, about one fourth grown when the flowers open the middle of May and then roughened above by short hairs and villose below, and at maturity thin, light yellow-green and scabrate on the upper surface, pale yellow-green on the lower surface, 2½′—3′ long, and 2′—2½′ wide, with a slender midrib often slightly hairy near the base, and 4 or 5 pairs of thin primary veins extending obliquely to the point of the lobes; petioles slender, densely villose early in the season, slightly hairy in the autumn, and ⅝′—1½′ in length; leaves at the end of vigorous shoots often truncate or slightly cordate at base, deeply lobed with broad triangular lobes, and 3½′—4′ long and wide, with a stout rose-colored glandular petiole, and hairy lunate glandular-serrate stipules. Flowers about ¾′ in diameter, on slender densely villose pedicels, in broad many-flowered hairy compound corymbs, their large linear to oblong bracts and bractlets occasionally persistent until midsummer; calyx-tube narrowly obconic, thickly covered with long spreading white hairs, the lobes abruptly narrowed at base, broad, acuminate, coarsely glandular-serrate, glabrous on the outer surface, villose on the inner surface; stamens 20; anthers pink; styles 4 or 5, surrounded at base by a narrow ring of pale tomentum. Fruit ripening from the middle to the end of September, on slender puberulous pedicels, in drooping few-fruited clusters, obovoid, broad and rounded at apex, gradually narrowed to the rounded base, crimson, lustrous, marked by small pale dots, ½′—⅝′ long, ⅜′—½′ in diameter; calyx only slightly enlarged, with closely appressed coarsely serrate lobes often deciduous from the ripe fruit; flesh yellow, thin, acidulous, juicy; nutlets 4 or 5, thin, gradually narrowed and acute at the ends, irregularly ridged and sometimes grooved on the back, about ⅜′ long.
