In the east the most northern station where I have seen the variety 

 growing is at Orbisonia, Huntington County, Pennsylvania.

Crataegus Harveyana (§ Intricatae), n. sp. 



Leaves ovate, acuminate at apex, cuneate and often unsymmetrical 

 at base, usually divided above the middle into short acute lobes, and 

 finely doubly serrate with straight gland-tipped teeth; early in the season 

 covered above by short white hairs, and pale and villose below along the 

 slender midrib and primary veins, and at maturity dull yellow-green and 

 smooth on the upper surface and paler and nearly glabrous on the lower 

 surface, 4-5 cm. long and 3-4 cm. wide; petioles slender, narrowly wing- 

 margined at apex, often glandular, densely villose early in the season, 

 becoming nearly glabrous, 1-2 cm. in length; leaves at the end of vigorous 

 shoots ovate, acute or acuminate at apex, rounded or cuneate at base, 

 deeply-lobed, coarsely serrate, 6-8 cm. long, and 4-6 cm. wide, their peti- 

 oles stout with broader margins and more numerous glands. Flowers 

 opening the middle of May, on stout pedicels thickly covered with long 

 white hairs, in many-flowered villose corymbs, with large oblong-obovate 

 sparingly villose glandular bracts and bractlets; calyx-tube broad-obconic, 

 covered with short matted white hairs, the lobes separated by wide 

 sinuses, acuminate, laciniately glandular- serrate above the middle, spar- 

 ingly villose on the outer surface, glabrous on the inner surface; stamens 

 20; anthers deep pink; styles 2 or 3. Fruit ripening the middle of Septem- 

 ber, subglobose, orange color, 1 cm. in diameter, the calyx little enlarged 

 with a deep narrow cavity pointed in the bottom and spreading often 

 deciduous lobes; flesh thin and dry; nutlets usually 3, gradually narrowed 

 and rounded at the ends, only slightly ridged on the back, 6-7 mm. long 

 and 5 mm. wide, the narrow dark hypostyle extending nearly to the middle. 



A shrub 2-2.5 mm. high, with stems covered with smooth dark bark, 



and slender nearly straight branchlets thinly covered early in their first 



season with white matted pale hairs, light red-brown and lustrous in their 



second season, becoming the following year ashy gray or dark brown, 



and armed with slender straight chestnut-brown spines 3.5-6 cm. in length.
