Crataegus pallescens n. sp. 
Glabrous with the exception of the hairs on the young leaves and 
calyx-lobes. Leaves ovate, acuminate, rounded or abruptly cuneate 
at the broad base, sharply and often doubly serrate with straight 
glandular teeth, and divided into five or six pairs of short acuminate 
spreading lobes; more than half-grown when the flowers open the 
middle of June and then thin, yellow-green, and covered above by 
short white hairs and glabrous and glaucescent below, and at matur- 
ity thin, glabrous, dark yellow-green on the upper surface and pale 
on the lower surface, 6.5 to 8.5 cm long and 6 to 8 cm wide, with 
thick midribs and thin primary veins arching obliquely to the points 
of the lobes; petioles slender, broadly wing-margined at the apex, 
glandular with conspicuous occasionally persistent glands, 2.5 to 3.5 
cm in length; stipules strap-shaped, acute, bright rose color, conspicu- 
ously glandular, often persistent until the flowers open; leaves on 
vigorous shoots abruptly cuneate at the base, more coarsely ser- 
rate and more deeply lobed, and sometimes 9 to 10 cm long and 
broad. Flowers 2.5 cm in diameter on long slender pedicels, in 
compact mostly ten- to fifteen-flowered corymbs, the lower peduncles 
from the axils of upper leaves ; calyx-tube broadly obconic, the lobes 
separated by wide sinuses, long, wide, acuminate, conspicuously 
glandular-serrate, slightly villose on the inner surface, reflexed after 
anthesis ; stamens ten; anthers deep red; styles four or five. Fruit 
ripening early in October on drooping red pedicels, short-oblong, 
rounded at the ends, cardinal-red, marked by occasional large pale 
“dots, pruinose, 1 to 1.2 cm in diameter; calyx prominent, with a 
short tube, a wide, deep cavity pointed in the bottom, and spreading 
prominent lobes; flesh thin, yellow, dry and mealy; nutlets four or 
five, gradually narrowed to the ends, rather broader at the apex than 
at the base, irregularly ridged on the back with a high narrow ridge, 
7 to 8 mm long and 4 to 4.5 mm wide, the broad hypostyle extend- 
ing one-third the length of the nutlet. 
An arborescent shrub 6 to 7 m tall, with stems sometimes 3 cm in 
diameter at the base, covered with dull ashy gray bark, ascending 
and spreading branches forming a thin open head, and stout slightly 
zigzag branchlets dark orange-green and marked by pale lenticels 
when they first appear, becoming pale chestnut-brown and lustrous 
at the end of their first season and armed with occasional stout 
slightly curved chestnut-brown shining spines 4 to 5 cm long and 
sometimes persistent and compound on old stems and branches.
