TREES OF NORTH AMERICA 



3-5, sometimes surrounded at the base by a ring of pale tomentum. Fruit ripening and 

 falling early in October, on short stout pedicels, in erect compact tomentulose clusters, 

 short-oblong, somewhat flattened at the rounded ends, bright crimson, very lustrous, 

 marked by occasional small white dots, about f ' long and f ' in diameter; calyx little en- 

 larged, the lobes small, lanceolate, coarsely glandular-serrate, tomentose on the upper 

 surface, erect and incurved, persistent; flesh thick, yellow, sweet and juicy; nutlets 3-5, 

 thin, dark colored, ridged and often grooved on the back, }' long. 



A tree, occasionally 35 high, with a straight trunk often a foot in diameter, covered 

 with dark red-brown fissured bark broken into small thick plate-like scales, stout generally 

 ascending branches forming an open usually narrow irregular head, and slender branchlets, 

 dark green and covered with matted pale hairs when they first appear, becoming bright 

 chestnut-brown and very lustrous during their first season, and light orange-brown the 

 following year, and armed with many stout nearly straight chestnut-brown spines rarely 

 more than I' in length. 



Distribution. Burlington, Chittenden County, Vermont, and southward through the 

 Champlain valley to Crown Point, Essex County and to the neighborhood of Albany, 

 New York; western Massachusetts to southern Connecticut (Stratford, Fairfield County); 



99. Crataegus pedicellate Sarg. 



Leaves broad-ovate or occasionally obovate or rhombic, acute or acuminate, broad- 

 cuneate or rounded at the entire base, coarsely often doubly serrate above with spreading 

 glandular teeth, and divided above the middle into 4 or 5 pairs of short acute or acuminate 



lobes, nearly two thirds grown when the flowers open during the last week in May, and 

 then roughened above by short rigid pale hairs and glabrous below, and at maturity mem- 

 branaceous, dark rich green and.scabrate on the upper surface, pale on the lower surface, 

 3'-4' long, and 2'-3' wide, with a slender midrib, and thin remote primary veins arching to 

 the point of the lobes; petioles slender, nearly terete, glandular with minute scattered 

 dark glands, at first villose, becoming glabrous, \%'-%%' in length; leaves at the end of 

 vigorous shoots sometimes truncate or slightly cordate at base, more deeply lobed, often 

 3'-4' long and 3' wide. Flowers f ' in diameter, on long thin pedicels, in loose lax 

 many-flowered slightly villose corymbs; calyx-tube narrowly obconic, glabrous, the lobes 

 broad, acute, very coarsely glandular-serrate; stamens usually 10; anthers rose color; 

 styles 5, surrounded at base by a conspicuous ring of pale tomentum. Fruit ripening and 

 falling during September, on long slender pedicels, in few-fruited drooping glabrous clus-
