lobes villose on the upper side and often deciduous from the ripe fruit; flesh thick, yellow, 

 rather juicy; nutlets usually 5, narrow and acute at the ends, ridged with a high broad ridge, 

 or rounded and slightly grooved on the back, about f ' long. 



A tree, 25-30 high, with a short trunk occasionally 4 '-5' in diameter, covered with 

 smooth light gray bark, numerous erect branches forming an oblong open very irregular

head, and stout slightly zigzag branchlets coated when they first appear with long matted 

 pale hairs, light red-brown and lustrous, marked by small pale lenticels, and pubescent at 

 the end of their first season, becoming dull red or orange-brown the following year, and 

 armed with stout straight or curved bright red-brown shining spines l|'-2' long.

 the Genesee River, Rochester, Munroe County, banks of the Niagara River, Niagara Falls, 

 Niagara County, and near Buffalo, Erie County; common. 



102. Crataegus delecta Sarg. 



Leaves broad-ovate, acute or acuminate at apex, rounded or broad-cuneate at the entire 

 base, sharply often doubly serrate above with straight glandular teeth, and divided usually 

 only above the middle into numerous short acuminate lateral lobes, when they unfold 

 tinged with red and covered with glistening white hairs more abundant below than above, 

 nearly half grown when the flowers open during the first half of May and then roughened 

 on the upper surface by short white hairs and glabrous or sparingly villose on the midrib 

 and veins below with scattered hairs sometimes persistent through the season, and at ma- 

 turity membranaceous, light yellow-green, lustrous and glabrous above, paler below, l|'-2' 

 long and wide, with a stout yellow midrib, and 6 or 7 pah's of slender primary veins arching 

 obliquely to the point of the lobes; turning purplish in the autumn before falling; petioles 

 slender, covered early in the season with matted pale hairs, becoming glabrous, slightly 

 glandular, often tinged with red below the middle, f'-l' in length; leaves at the end ol 

 vigorous shoots sometimes long-pointed at apex and slightly cordate at base, more deepty 

 lobed and more coarsely serrate, and often 3'-4' long and wide. Flowers f'-l' ifi diameter, 

 on long slender slightly hairy pedicels, in broad villose 10-15-flowered sparingly villose 

 corymbs, with glandular caducous bracts and bractlets; calyx-tube broadly obconic, villose 

 or nearly glabrous, the lobes acuminate, coarsely glandular-serrate, glabrous on the outer 

 surface, villose on the inner surface; stamens 5-10, usually 5; anthers dark rose color; 

 styles 3-5, usually 5. Fruit ripening from the first to the middle of September and soon 

 falling, on stout glabrous pedicels, in drooping few-fruited clusters, subglobose to slightly
