1901] Sargent, — Crataegus in the Champlain Valley 25 
2 in. long and 14 to 2 in. wide, with midribs deeply impressed above 
and few slender primary veins ; petioles very slender, nearly terete, 
1 to 14 in. in length, sometimes glandular on leading shoots. Flow- 
ers ł in. in diameter on short stout pedicels, in compact many- 
flowered corymbs; bracts and bractlets lanceolate, conspicuously 
glandular-serrate, bright red, caducous ; calyx broadly obconic, the 
lobes lanceolate from broad bases, entire or obscurely glandular- 
serrate, tipped with conspicuous bright red glands, reflexed after 
anthesis; stamens usually 1o, sometimes 5 to ro, rarely 20; fila- 
ments slender, elongated ; anthers small, rose-purple; styles 2 to 5 
usually 2 or 3. Fruit in loose drooping clusters, oblong, bright 
scarlet, lustrous, marked with large pale scattered lenticels, about 4 
in. long and 4 in. thick ; calyx-cavity broad and shallow, the lobes 
elongated, spreading or appressed, sometimes erect and incurved, 
often deciduous; flesh thick, bright yellow, dry and mealy; nutlets 
usually 2 or 3, occasionally 4, broadly ridged on the back, about 1 
in. long. 
A broad bush often 15 feet in height with numerous thick stems 
standing erect and remote from one another at the top and thus form- 
ing an open broad head, and stout branchlets marked with oblong 
pale lenticels, bright chestnut-brown and lustrous during their first 
season, ashy gray during their second year, and armed with numer- 
ous spines, on some plants short and stout, on others elongated, more 
slender and straight or incurved. Flowers at the end of May. Fruit 
ripens from the 2oth of September to the roth of October and usually 
hangs on the branches until long after the leaves have fallen. 
Rich hillsides and pastures, common from the Champlain Valley 
and Berkshire County, Massachusetts, to central and southern Massa- 
chusetts. 
Easily distinguished from the other New England species of this 
group by the erect remote ends of the stems, by the thicker blue- 
green leaves pale on the lower surface, which hang down conspicu- 
ously on their slender petioles when the flowers are open. 
C. pentandra. Leaves oval to ovate, acuminate, broadly cuneate 
or rarely rounded at the base, incisely divided above the middle into 
numerous short acute lobes, coarsely and often doubly glandular- 
serrate with spreading or incurved teeth, membranaceous, dark 
green and roughened above with short rigid pale hairs, pale and gla- 
brous below, 2 to 24 in. long, from 13 to 2 in. wide, with slender mid- 
ribs and thin primary veins running to the points of the lobes, or on 
vigorous shoots often from 34 to 4 in. long and 3 in. wide; petioles 
slender, often slightly winged above, grooved, glandular with minute 
scattered dark glands, about r in. long. Flowers 2 in. in diameter 
in few-flowered compact glabrous thin-branched cymes ; bracts and 
bractlets narrowly obovate to linear-lanceolate, obscurely glandular- 
serrate, light red ; calyx obconic, glabrous, dark red, the lobes linear- 
lanceolate, entire and finely glandular-serrate, incurved after anthesis ;
