CRAT^GUS LIVONIANA, Sarg. 



(Crus-galli.) 

 Crataegus livoniana, n. sp. 



Glabrous with the exception of the hairs on the upper surface of the young leaves and on the 

 calyx-lobes. Leaves oblong-obovate, acute or rounded at the apex, gradually narrowed to the 

 long slender concave-cuneate entire base, and finely often doubly serrate above, with straight or 

 incurved glandular teeth ; slightly tinged with red and villose, with scattered pale hairs, especially 

 on the midribs, when they unfold, about half grown when the flowers open and then thin, yellow- 

 green, and still slightly hairy above and pale yellow-green below, and at maturity subcoriaceous, 

 dark yellow-green, very lustrous and glabrous on the upper surface, pale bluish green on the 

 lower surface, from 5 to 6 centimetres long and from 3 to 4 centimetres wide, with stout midribs, 

 and slender conspicuous primary veins extending very obliquely toward the apex of the leaf; petioles 

 stout, wing-margined to below the middle, slightly villose on the upper side while young, soon 

 becoming glabrous, often rose color in the autumn, from 1 to 1.2 centimetres in length ; leaves on 

 vigorous shoots coriaceous, rhombic to obovate or oval, short-pointed at the rounded apex, more 

 coarsely serrate, occasionally slightly lobed above the middle, and often from 6 to 7 centimetres 

 long and from 5 to 5.5 centimetres wide. Flowers from 2 to 2.2 centimetres in diameter, on 

 long slender pedicels, in wide lax mostly ten to eighteen-flowered corymbs, the elongated lower 

 peduncles from the axils of the upper leaves ; calyx-tube broadly obconic, the lobes separated by 

 wide sinuses, gradually narrowed from the base, long, slender, acuminate, conspicuously glandular- 

 serrate, reflexed after anthesis ; stamens twenty ; anthers faintly tinged with pink before anthesis, 

 becoming cream color ; styles from two to four, surrounded at the base by a narrow ring of pale 

 hairs. Fruit on long slender reddish pedicels, in drooping many-fruited clusters, subglobose to 

 short-oblong, full and rounded at the ends, depressed at the insertion of the stalk, dark crimson, 

 lustrous, marked by numerous large pale dots, from 1.2 to 1.4 centimetres in diameter; calyx 

 prominent, with a wide deep cavity tomentose in the bottom, and long spreading coarsely glandu- 

 lar-serrate lobes slightly hairy on the upper side ; flesh thick, dark orange color, sweet, dry, and 

 mealy ; nutlets from two to four, gradually narrowed to the rounded ends, or when two semi- 

 osbicular, ridged on the back, with a high broad deeply grooved ridge, from 7 to 7.5 millimetres 

 long and about 5 millimetres wide. 



A tree, from 6 to 7 metres high, with a trunk 2 to 3 decimetres in diameter, covered with dark 

 gray scaly bark, large erect and spreading branches, and stout slightly zigzag drooping branchlets 

 dark orange-green and marked by pale lenticels when they first appear, becoming light orange- 

 brown and lustrous in their first season and pale gray-brown the following year, and armed with 

 numerous stout nearly straight light chestnut-colored ultimately purplish shining spines from 

 5.5 to 6 centimetres long. Flowers appear late in May. Fruit ripens the middle of October.
