(Tomentosse. ) 

 CRATAEGUS MOLLITA, n. Sp. 



Leaves ovate to oval or slightly obovate, acuminate, gradually or abruptly narrowed and 

 concave-cuneate at the entire base, coarsely doubly serrate above, with straight glandular teeth, 

 and slightly divided above the middle into three or four pairs of small acuminate spreading lobes ; 

 nearly full grown when the flowers open and then thin, dark yellow-green and covered above by 

 short white hairs most abundant along the midribs, and pale and villose below, and at maturity 

 thin, yellow-green, lustrous and glabrous on the upper surface, light yellow-green and still villose 

 on the lower surface, from 7 to 8 centimetres long and from 4.5 to 6 centimetres wide, with 

 slender midribs, and thin primary veins extending obliquely to the points of the lobes ; petioles 

 slender, narrowly wing-margined often to below the middle, densely pubescent early in the season, 

 becoming almost glabrous, often rose color in the autumn, from 8 to 10 millimetres in length ; 

 leaves on vigorous shoots rather thicker, coarsely serrate, and often from 9 to 10 centimetres long 

 and from 6.5 to 8.5 centimetres wide. Flowers 1 centimetre in diameter, on short stout densely 

 villose pedicels, in wide mostly eighteen to twenty-five-flowered corymbs, the long stout villose 

 lower peduncles from the axils of upper leaves ; calyx-tube narrowly obconic, thickly coated with 

 long matted white hairs, the lobes long, abruptly narrowed from broad bases, wide, acuminate, 

 glandular-serrate, glabrous on the outer surface, villose on the inner surface, reflexed after anthesis ; 

 stamens from five to eight, usually five or six ; anthers pale rose color ; styles two or three, sur- 

 rounded at the base by a ring of long white hairs. Fruit on stout spreading glabrous reddish 

 stems, in many-fruited clusters, subglobose to short-oblong, orange-red, lustrous, marked by large 

 pale dots ; calyx little enlarged, with a narrow deep cavity, and small spreading or incurved gen- 

 erally persistent lobes ; flesh thick, yellow, soft, and succulent ; nutlets two or three, full and 

 rounded at the ends, ridged on the back, with a broad low slightly grooved ridge, irregularly 

 penetrated on the inner faces by broad deep cavities, from 6.5 to 7 millimetres long and from 4 

 to 4.5 millimetres wide. 



A tree, from 5 to 8 metres high, with a slender trunk, small spreading branches forming a 

 narrow open head, and slender nearly straight branchlets covered when they first appear with 

 matted pale hairs, becoming dark orange color, verrucose and puberulous in their first season and 

 ashy gray the following year, and unarmed or armed with nearly straight slender ashy gray spines 

 from 2.5 to 3 centimetres in length. Flowers from the 20th to the end of May. Fruit ripens the 

 end of September.
