CRATAEGUS VTLLIFLORA, Saeg. 



(Crus-galli.) 

 Crat^jgus villiflora, n. sp. 



Leaves obovate-cuneate, rounded or rarely acute at the apex, and coarsely doubly serrate above 

 the middle, with straight glandular teeth ; deeply tinged with red and covered with long white 

 hairs when they unfold ; more than half grown when the flowers open and then thin, yellow-green 

 and setose above and pale and villose below on the midribs and veins, and at maturity subcori- 

 aceous, dark green, lustrous and scabrate on the upper surface, on the lower surface scabrous 

 and slightly villose along the slender yellow midribs and thin prominent primary veins, from 3.5 

 to 4 centimetres long and from 2.5 to 3 centimetres wide ; petioles stout, narrowly wing-margined 

 nearly to the base, villose while young, becoming glabrous, from 6 to 8 millimetres in length ; 

 leaves on vigorous shoots thicker, acute at the apex, and often from 4.5 to 5 centimetres long and 

 from 2 to 2.2 centimetres wide, with foliaceous lunate coarsely serrate deciduous stipules. Flowers 

 from 1.2 to 1.4 centimetres in diameter, on short slender densely villose pedicels, in compact 

 hairy seven to fifteen, usually seven or eight-flowered, corymbs, the lower peduncles from the 

 axils of upper leaves ; calyx-tube narrowly obconic, thickly coated with matted pale hairs, the 

 lobes wide, acute, slightly denticulate near the middle or nearly entire, glabrous on the outer 

 surface, villose on the inner surface, reflexed after anthesis ; stamens from five to ten, usually ten ; 

 anthers light yellow ; styles two or three, surrounded at the base by a ring of yellowish hairs. 

 Fruit on short nearly glabrous spreading or erect stems, in few-fruited clusters, short-oblong, full 

 and rounded at the ends, green more or less deeply tinged with crimson, from 8 to 9 millimetres 

 long and nearly as broad ; calyx little enlarged, with a wide deep cavity, and small spreading and 

 sometimes incurved persistent lobes ; flesh thin, yellow-green, dry, and mealy ; nutlets two or three, 

 gradually narrowed to the rounded ends or acute at the apex, ridged on the back, with a high 

 deeply grooved ridge, from 6.5 to 7 millimetres long and from 4 to 4.5 millimetres wide. 



A tree, from 4 to 7 metres high, with a stem from 7 to 14 centimetres in diameter, horizontal 

 branches forming a broad flat-topped head, and slender nearly straight branchlets dark orange- 

 green and villose when they first appear, becoming light chestnut-red, marked by pale lenticels 

 and pubescent or puberulous in their first season and dull gray-brown the following year, and 

 armed with few stout straight spines usually from 1.2 to 2.5 centimetres long, but on vigorous 

 shoots sometimes 3 centimetres in length. Flowers appear during the first week of May. Fruit 

 ripens early in October.
