Niagara Falls, J. Dunbar (#32, type), September 28, 1905, and 

 May 28, 1906. 



Similar to Crataegus pausiaca Ashe, in habit, in the 

 color of the branchlets and in the shape and venation of the leaves, 

 this species differs from it in its larger flowers on much shorter 

 pedicels, in the more villose calyx-tube and much broader, more 

 foliaceous calyx-lobes, and in the smaller subglobose crimson fruit 

 on shorter stalks. 



Crataegus notabilis n. sp. 



Leaves rhombic, acuminate, gradually narrowed and acute at 

 the entire base, coarsely doubly serrate above, with incurved or 

 straight glandular teeth, and diviued above the miudle into 2 or 3 

 pairs of small acuminate spreadmg lobes; wnen tney unfold slightly 

 tinged with red and glabrous witli the exception of a few scattered 

 pale hairs along the upper side of the midribs, membranaceous and 

 about half grown when the flowers open at the end of May, and 

 at maturity thick and firm, glabrous, smooth and dark yellow-green 

 on the upper surface, pale blue-green on the lower surface, 6-7 cm 

 long and 4-4.5 cm wide, with prominent yellow midribs, and thin 

 primary veins extending very obliquely to the points of the lobes; 

 petioles slender, broadly wing-margined often to below the middle, 

 occasionally furnished early in the season with minute deciduous 

 glands, glabrous, 2-3 cm in length ; stipules linear, glandular, fading 

 brown, caducous. Flowers 1.2 cm in diameter, on long slender 

 glabrous pedicels, in usually 6-8-flowered lax thin-branched corymbs, 

 with linear bracts and bractlets, the lower peduncles from the axils 

 of the upper leaves; calyx-tube broadly obconic, glabrous, the lobes 

 slender, acuminate, entire or slightly dentate above the middle, 

 glabrous on the outer, slightly villose on the inner surface, reflexed 

 after anthesis; stamens 20; filaments persistent on the ripe fruit; 

 anthers large, red-purple; styles 3-5. Fruit ripening early in 

 October, on long drooping pedicels, in few-fruited clusters, short- 

 oblong or slightly obovate, full and rounded at, the ends, orange-red, 

 marked by occasional large dark dots, 8-10 mm long, 7-8 mm in 

 diameter; calyx prominent, with a short tube, a deep narrow cavity, 

 and slender spreading persistent lobes ; flesh thin, yellow, hard and 

 dry ; nutlets 3-5, rounded at the ends, ridged on the back, with a 

 broad, low grooved ridge, light colored, 5-6 mm long, and about 

 4 mm wide.
