TREES AND SHRUBS. 



CRATAEGUS LANCEOLATA, Saeg. 



Crataegus lanceolata, n. sp. 



Glabrous with the exception of the hairs on the young leaves and petioles. Leaves lanceolate, 

 gradually narrowed and concave-cuneate at the entire base, and crenulate-serrate usually only 

 above the middle ; nearly full grown when the flowers open, and then thin, yellow-green, spar- 

 ingly villose along the midribs above and paler and furnished below with small tufts of axillary 

 hairs, and at maturity thin but firm in texture, yellow-green, smooth, glabrous, and lustrous on the 

 upper surface, pale and nearly glabrous on the lower surface, from 4.5 to 5.5 centimetres long 

 and from 2.5 to 3 centimetres wide, with slender midribs often rose color in the autumn, and thin 

 obscure primary veins ; petioles slender, slightly wing-margined at the apex, sparingly villose 

 while young, soon glabrous, often rose color in the autumn, from 1.2 to 2 centimetres in length ; 

 leaves on vigorous shoots thicker, oblong-ovate, long-pointed and acuminate at the apex, gradu- 

 ally narrowed and concave-cuneate at the base, coarsely glandular-serrate, deeply divided into 

 three or four pairs of broad acuminate lateral lobes, from 7 to 9 centimetres long and from 5.5 to 

 6.5 centimetres wide, with long broadly winged petioles, and slender foliaceous lunate coarsely 

 glandular-serrate persistent stipules. Flowers from 1.5 to 1.7 centimetres in diameter, on very 

 long slender pedicels, in wide lax mostly ten to twelve-flowered corymbs, the lower peduncles 

 from the axils of upper leaves ; calyx-tube narrowly obconic, the lobes slender, acuminate, entire, 

 reflexed after anthesis; stamens twenty; anthers pale yellow; styles four or five. Fruit on 

 slender elongated drooping stems, in many-fruited clusters, short-oblong to slightly obovate, grad- 

 ually narrowed and rounded at the ends, orange-red, lustrous, marked by occasional large dark 

 dots, from 7 to 8 millimetres long and from 6 to 7 millimetres in diameter ; calyx little enlarged, 

 with a short tube, a deep narrow cavity, and usually persistent lobes abruptly narrowed from 

 broad bases, slender, erect and incurved, and dark red on the upper side below the middle; flesh 

 thin, light yellow, soft, and mealy ; nutlets four or five, acute at the base, narrowed and rounded 

 at the apex, rounded and slightly grooved or irregularly ridged on the back, with a low thin 

 ridge, about 5 millimetres long and from 2.5 to 3 millimetres wide. 



A tree, from 8 to 10 metres high, with a fluted trunk from 1 to 1.5 decimetres in diameter, 

 covered with light gray scaly bark, the narrow scales in separating disclosing the orange-colored 

 inner bark, large spreading ascending branches drooping at the ends and forming a wide open 

 handsome head, and slender nearly straight branchlets dark green tinged with red and marked by 

 large pale lenticels when they first appear, becoming orange-red and lustrous in their first season 

 and pale gray-brown the following year, and usually unarmed. Flowers appear during the first 

 week of May. Fruit ripens late in October or early in November. In the autumn the leaves 

 turn dark orange color before falling.

 (No. 4 type), May 6 and November 4, 1902. 



This handsome species is well distinguished from the related Crataegus viridis, Linnaeus, by its thicker lanceolate, 

 not ovate or obovate, leaves, by the much longer pedicels of the flowers, and by the orange-red, not scarlet, fruit, and 

 scaly bark.
