Crataegus clintoniana n. sp. 



Leaves ovate, acuminate, cuneate or rounded at the entire base, 

 finely and often doubly serrate above, with straight glandular teeth, 

 and divided into 4 or 5 pairs of narrow acuminate lateral lobes ; when 

 they unfold tinged with red, sparingly villose on the upper surface 

 and villose below along the midribs and veins and furnished with 

 axillary tufts of matted pale hairs, nearly half grown when 

 the flowers open about the 20th of May and then thin, light yellow- 

 green, still sparingly hairy principally along the under side of the 

 midribs and veins and pale bluish green below, and at maturity thin, 

 yellow-green, smooth and glabrous on the upper surface and nearly 

 glabrous on the lower surface, 4-5 cm long and 3.5-4 cm wide, 

 with slender midribs, and usually 4 pairs of thin primary veins; 

 petioles slender, slightly wing-margined at the apex, glabrous, spar- 

 ingl}^ glandular while young, 1-1.5 cm in length; leaves on vigorous 

 shoots abruptly cuneate or rounded at the broad base, coarsely 

 serrate, deeply lobed, often 6-7 cm long and broad, with stout 

 broadly winged glandular petioles 2.5-3 ^^'^^ ^^^ length. Flowers 2 

 cm in diameter, on slender villose pedicels, in compact mostly 5- 

 or 6-flowered corymbs; calyx-tube narrowly obconic, glabrous, the 

 lobes slender, acuminate, nearly entire, glabrous, reflexed after 

 anthesis ; stamens 20; anthers bright red; styles 3-5, generally 5, 

 surrounded at the base by a broad ring of pale hairs. Fruit ripen- 

 ing early in October, on stout reddish pedicels, in few-fruited erect 

 clusters, subglobose but often rather broader than high, distinctly 

 angled, orange-red, lustrous, marked by numerous small pale dots, 

 1. 2-1. 4 cm in diameter; calyx prominent, wnth a short tube, a broad 

 dee^;;) cavity, and small spreading or reflexed lobes persistent on the 

 ripe fruit; flesh thick, yellowish green, dry and mealy; nutlets
