 Crataegus palliata, n. sp. (Crus-galli.) 



Leaves oval to obovate, acute or acuminate, concave cuneate at the entire base, coarsely doubly serrate with straight glandular 

 teeth, and on vigorous shoots slightly lobed ; about half-grown when the flowers open and then thin, light yellow-green, roughened 

 above by short white hairs and pale and covered below with short hairs most abundant on the midribs and veins, and at maturity 

 subcoriaceous, dark green, smooth, glabrous and lustrous on the upper surface, villose-pubescent on the lower surface, from 6 to 

 8 centimetres long and from 3.5 to 5.5 centimetres wide, with stout midribs and thin prominent primary veins ; petioles stout, 

 broadly wing-margined to below the middle, densely villose early in the season, becoming glabrous, 6 or 7 centimetres in length. 

 Flowers about 1.8 centimetres in diameter, on slender villose pedicels, in generally from ten- to twelve-flowered hairy corymbs ; 

 calyx-tube narrowly obconic, densely coated with matted pale hairs, the lobes gradually narrowed from wide bases, slender, acu- 

 minate, finely glandular-serrate below the middle, villose, reflexed after anthesis ; stamens ten ; anthers dark rose color or pur- 

 ple ; styles from two to five, surrounded at the base by a ring of long white hairs. Fruit subglobose, deep dark red, lustrous, 

 marked by pale dots, about 2 centimetres in diameter ; flesh thick, soft and succulent ; nutlets usually from three to five, rounded 

 at the base, narrowed and sometimes acute at the apex, irregularly ridged on the back with a grooved ridge, from 7 to 8 millime- 

 tres long and about 4 millimetres wide, the narrow light-colored hypostyle extending to the middle of the nutlet. 



A tree, sometimes 7 metres high, with stout very zigzag branchlets thickly coated when they first appear with long matted 

 white hairs, becoming glabrous, light chestnut-brown and very lustrous during their first season and pale gray-brown the follow- 

 ing year, and armed with many stout nearly straight chestnut-brown shining spines from 6 to 8 centimetres in length. Flowers 

 toward the end of April. Fruit ripens in October.

 Crataegus triumphalis, n. sp. (Crus-galli.) 



Leaves oblong-ovate, acute and often short-pointed at the apex, gradually narrowed and concave-cuneate at the base, and finely 

 s above the middle with straight teeth; nearly fully grown when the flowers open and then thin, yellow-green and clothed 

 3 and blue-green and glabrous below with the exception of a few hairs along the midribs, and at maturity 

 nd very lustrous on the upper surface, paler on the lower surface, from 4 to 5 centimetres 

 , with thin midribs and slender prominent primary veins ; petioles slender, narrowly-wing- 

 margined to below the middle, densely villose early in the season, becoming glabrous, from 5 to 6 millimetres in length ; leaves 

 on vigorous shoots broad-obovate, rounded at the apex, coarsely serrate, often from 5 to 6 centimetres long and from 3 to 3.5 

 centimetres wide. Flowers from 2.3 to 2.5 centimetres in diameter, on slender villose pedicels, in few-flowered hairy corymbs ; 

 calyx-tube narrowly obconic, villose with scattered pale hairs most abundant near the base, the lobes slender, acuminate, entire, 

 glabrous on the outer surface, villose on the inner surface ; stamens ten ; anthers pale rose color; styles two or three, usually two. 

 Fruit on slender drooping pedicels, ovate or short-oblong, full and rounded at the ends, crimson often tinged with green, lustrous, 

 marked by numerous small pale dots, from 1 to 1.5 centimetres long, and from 8 to 10 millimetres in diameter; calyx little- 

 enlarged, with a deep narrow cavity pointed in the bottom, and spreading reflexed lobes ; flesh thin, yellow-green, dry, hard and 

 mealy ; nutlets two or three, rounded at the ends, broader at the apex than at the base, ridged on the back with a high grooved ridge, 

 from 6 to 7 millimetres long and about 4 millimetres wide, the narrow prominent hypostyle extending to the middle of the nutlet. 



A tree, from 5 to 10 metres high, with a trunk from 8 to 10 centimetres in diameter, covered with rough scaly bark, spreading 

 branches, and slender zigzag branchlets light chestnut-brown and coated when they first appear with long matted pale hairs, nearly 

 glabrous at the end of their first season and pale gray-brown the following year, and armed with very numerous slender nearly 

 straight chestnut-brown shining spines from 2 to 3 centimetres in length. Flowers at the'end of April. Fruit ripens in October.

 Crataegus bellica, n. sp. (Crus-galli.) 



Leaves erect on the branches, broadly obovate and rounded at the apex, gradually narrowed and cuneate at the base, and finely 

 often doubly serrate usually only above the middle ; more than half grown when the flowers open and then villose on the midribs 

 above with hairs persistent during the season, and glabrous below, and at maturity subcoriacgous, dark green and lustrous on the 

 upper surface, pale on the lower surface, from 3.5 to 4 centimetres long and from 2 to 2.5 centimetres wide, with stout midribs, 

 and slender prominent primary veins ; petioles stout, narrowly wing-margined to the base, from 6 to 8 millimetres in length, 

 leaves on vigorous shoots obovate, acute and short-pointed at the apex, concave-cuneate at the base, coarsely serrate, often from 

 G to 7 centimetres long and 3.5 centimetres wide. Flowers from 1.6 to 1.8 centimetres in diameter,on slender slightly villose pedicels, 

 in compact from six- to fifteen-flowered corymbs; calyx-tube narrowly obconic, glabrous, the lobes short, generally narrowed from 

 the wide base, acute, entire or occasionally dentate below the middle, glabrous on the outer surface, villose on the inner surface, 

 reflexed after anthesis; stamens from five to ten, usually ten ; anthers pale pink; styles two. Fruit (immature) short oblong to ovate, 

 rounded at the base, gradually narrowed at the apex, from 1 to 1.2 centimetres long and from 1 to 10 millimetres in diameter ; 

 calyx prominent with a broad shallow cavity pointed in the bottom, and reflexed closely appressed lobes ; flesh thin, dry and hard ; 

 nutlets two, rounded at the base, slightly narrowed and rounded at the apex, ridged on the back with a broad high deeply grooved 

 ridge, from 5 to 7 millimetres long and about 4 millimetres thick, the broad hypostyle extending to about the middle of the nutlet.
