 13. Crataegus fulva n. sp. 



Leaves oval, acute or acuminate, cuneate or concave-cuneate at the 

 entire or glandular base, finely doubly serrate above, with straight 

 gland-tipped teeth, and slightly divided usually only above the middle 

 into 3 or 4 pairs of short broad acute lobes, when they unfold deeply 

 tinged with red, and hairy above, with soft white hairs, about half- 

 grown when the flowers open from the 20th to the 25th of May, and 

 then dark green and still slightly hairy above and pale below, and at 

 maturity membranaceous, dark bluish-green, very smooth, and glab- 

 rous or nearly glabrous on the upper and pale or glaucous on the lower 

 surface, 4.5-5 cm. long and 3-4 cm. wide, with thin orange-colored 

 midribs and 3 or 4 pairs of slender primary veins; petioles slender, 

 grooved on the upper side, slightly wing-margined at the apex, glandu- 

 lar, with minute dark scattered persistent glands, often orange color 

 at maturity, 1.5-2.5 cm. in length; stipules linear-obovate, glandular, 

 fading brown or red, mostly deciduous before the flowers open; leaves 

 on vigorous shoots often ovate, full and rounded at the serrate base, 

 sometimes deeply lobed, about 7 cm. long and 6 cm. wide. Flowers 

 2-2.5 cm. in diameter, on slender reddish-glabrous pedicels, in small 

 1-6-flowered simple corymbs, with obovate to linear dark red glandular- 

 serrate viscid bracts and bractlets; calyx-tube broadly obconic, the 

 lobes wide, acuminate, coarsely glandular-serrate usually only above 

 the middle; stamens 5-9; anthers pale pink; styles 2-4, usually 3-4. 

 Fruit ripening early in October and falling with or after the leaves, on 

 slender erect pedicels, solitary or in 2- or 3-flowered clusters, obovate, or 

 when fully ripe oblong-globose to globose, rounded at the apex, gradu- 

 ally narrowed at the base, orange color tinged with red or red-bronze, 

 1-1.3 cm. long and 8-12 mm. wide; calyx only slightly enlarged, with 

 a short tube, a wide deep cavity, and spreading and reflexed lobes 

 deciduous from the ripe fruit; nutlets 3 or 4, full and obtuse at the 

 ends, very slightly ridged on the broad rounded back, about 6 mm. 

 long and 3-4 mm. wdde. 



A shrub 1-2 m. high, with few thin wand-like stems, covered with 

 green or yellow-gray bark, very slender nearly straight branchlets 

 marked by occasional large pale lenticels, dark reddish-brown when they 

 first appear, chestnut-brown and lustrous during their first winter and 

 dull gray-brown the following year, and armed with few very slender 

 nearly straight purplish shining spines 2-4 cm. long.
