Crataegus dissociabilis n. sp. 



Leaves broadly ovate to triangular, acuminate, rounded, truncate 

 -or abruptly cuneate at the wide entire base, finely often doubly 

 serrate above, with small glandular teeth, and slightly divided usually 

 only above the middle into 3 or 4 pairs of small acuminate lobes; 

 when they unfold deeply tinged with red and covered on the upper 

 surface with soft white hairs and slightly hairy in the axils of the 

 veins below, nearly fully grown when the flowers open late in May 

 or early in June, and then thin, light yellow-green, scabrate and 

 slightly hairy on the midribs above, and at maturity thin, yellow- 

 green, slightly roughened and lustrous on the upper surface, pale 

 bluish green on the lower surface, 3.5-4 cm long and 3-4 cm wide, 

 with thin midribs, and primary veins arching obliquely to the points 

 of the lobes ; petioles slender, slightly wing-margined at the apex, 

 glandular while young, with mostly deciduous glands, 1.5-3 ^^ ^^^ 

 length. Flowers 1.5-2 cm in diameter, on slender glabrous pedicels, 

 in compact mostly 5-10-flowered corymbs, with linear-obovate to 

 linear glandular bracts and bractlets fading brown and deciduous 

 before the flowers open, the long lower peduncles from the axils of 

 upper leaves ; calyx-tube narrowly obconic, glabrous, the lobes grad- 

 ually narrowed from the base, slender, glabrous, red and glandular 

 at the acuminate apex, irregularly and coarsely glandular serrate 

 usually only below the middle, reflexed after anthesis ; stamens 

 5-10; anthers pale rose color; styles 3 or 4. Fruit ripening 

 and falling late in September, on long slender drooping pedicels, 

 in few-fruited clusters, obovate, full and rounded at the apex, 

 abruptly narrowed at the base, light cherry-red, very pruinose, 

 marked by large pale dots, about i cm long and 9 mm in diameter ; 

 calyx little enlarged, v/ithout a tube, with a wide deep cavity narrow 

 in the bottom, and small spreading lobes dark red on the upper side ;

 the base, gradually narrowed and rounded at the apex, ridged on 

 the back, with a broad deeply grooved ridge, 6-"] mm long, and 4-4.5 

 mm wide. 



An arborescent shrub 3-4 m high, with a short stem sometimes 

 1.5 dm in diameter, covered near the ground with dark scaly bark, 

 small ascending and spreading branches, and slender nearly straight 

 glabrous-branchlets, dark orange-green tinged with red when they
