that name (Arb. Brit, ii. 817, f. 566), which cannot be satisfactorily 
determined, certainly represents another plant. 
C. matura. Leaves oval or rhomboidal to ovate-oblong, acute 
or acuminate, cuneate or on vigorous shoots often rounded at the 
broad base, incisely divided into numerous short acute spreading 
lobes, finely doubly serrate often nearly to the very base with glan- 
dular incurved teeth, covered on the upper surface while young 
with short soft fine hairs and at maturity membranaceous, glabrous, 
dark rich green above, paler and yellow-green below, from 2 to 3 in. 
long and from 14 to 2 in, wide, with thin midribs slightly impressed 
above and slender primary veins arching to the points of the lobes ; 
petioles slender, nearly terete, often slightly winged above on vigor- 
ous shoots, glandular, from 1 to 14 in. in length. Flowers in broad 
many-flowered slender branched cymes; calyx cup-shaped, glabrous, 
the lobes lanceolate, acute, slightly and irregularly glandular-serrate 
or entire, villose on the upper surface, reflexed after anthesis; sta- 
mens 20; filaments slender, elongated ; anthers minute; styles s. 
Fruit in erect or drooping clusters; oblong, full and rounded at the 
ends, ł in. long, $ in. thick, lustrous, dark purplish crimson when 
fully ripe; calyx cavity deep and narrow, the lobes small, slightly 
glandular-serrate or entire, villose above, prominently ribbed below, 
usually erect, persistent; flesh thick, yellow, soft and pulpy; nutlets 
5, thin, dark-colored, rounded and ridged on the back with high 
thick ridges, 4 in. long. f 
A shrub from 6 to ro feet high with slender stems and glabrous 
lustrous orange-brown branchlets becoming ashy gray during their 
second season, and armed with few usually straight spines from 1 to 
2 in. in length. 
Rocky hillsides, common. Flowers at the end of May. Fruit

Well distinguished from the other species of this group by its 20 
stamens and by the early ripening of the fruit, which probably 
matures earlier than that of any other New England species. 
C. pastorum. Glabrous with the exception of a few scattered 
pale hairs on the upper surface of the unfolding leaves. Leaves 
ovate, acute, full and rounded or occasionally cuneate or on vigor- 
ous shoots cordate at the broad base, slightly divided above the 
middle into short broad acute lobes, doubly serrate with usually 
straight teeth tipped with dark red glands, bronze red as they unfold, 
at maturity thick and firm in texture, dark dull blue-green on the
