TOMENTOSAE 



Crataegus efferata n. sp. 



Leaves oblong-ovate to rhombic, acute or acuminate at the apex, 

 abruptly or acutely concave-cuneate at the entire base, finely often 

 doubly serrate above, with straight or incurved glandular teeth, and 

 sometimes slightly divided above the middle into 3 or 4 pairs of 

 small acute lobes ; more than half grown when the flowers open the 

 last days of May and then very thin, yellow-green and slightly hairy 

 above on the midribs and covered below by soft pale hairs, and at 

 maturity thin but firm in texture, light yellow-green, very smooth 

 and glabrous on the upper surface, pale and villose-pubescent on the 

 lower surface on the stout often rose colored midribs and slender 

 primary veins and veinlets, 5.5-7.5 cm long and 4-6 cm wide; 

 petioles stout, narrowly wing-margined often to the base, hairy on 

 the upper side while young, becoming nearly glabrous and often 

 dark rose color in the autumn, 1.5-1.8 cm in length; leaves on 

 vigorous shoots thicker, more coarsely serrate, more deeply lobed, 

 and often 7-8 cm long and 5-6 cm wide. Flowers about 1.2 cm in 

 diameter, on long slender slightly villose pedicels, in small rather 

 compact io-15-flowered hairy corymbs, the lower peduncles from 

 the axils of upper leaves; calyx-tube narrowly obconic, coated with 

 short white hairs, the lobes abruptly narrowed at the base, long, 

 wide, acuminate, laciniately glandular serrate, glabrous on the outer, 

 slightly villose on the inner surface, reflexed after anthesis; stamens 

 16-20; anthers light rose color; styles 2 or 3. Fruit ripening 

 early in October, on long slender slightly hairy red pedicels, in 

 few- fruited spreading or drooping clusters, subglobose, scarlet, very 

 lustrous, marked by large pale dots, 8-9 mm in diameter; calyx 

 prominent, with a deep narrow cavity, and long spreading lobes 

 dark red on the upper side below the middle ; flesh thick, yellow- 

 green, becoming soft and succulent when fully ripe ; nutlets usually 

 2, nearly orbicular, rounded and slightly ridged on the back, pene- 

 ti ated on the inner face by long narrow deep cavities, 4.5-5 n^ni long, 

 and 3-3.5 mm wide. 



An arborescent shrub 5-7 m high, with stout stems covered with 

 dark brown scaly bark, erect and spreading branches, and stout 

 slightly zigzag glabrous branchlets light orange-yellow when they 

 first appear, becoming dark chestnut-brown, very lustrous and 

 marked by small pale dark lenticels in their first season and dull 

 reddish brown the following year, and armed with numerous very
