TENUIFOLIAE. 
C. acutiloba. Leaves ovate, acute, rounded or wedge-shaped at 
the base, laciniately cut into four or five pairs of acute or acuminate 
narrow lobes, their tips entire, spreading, and often more or less 
curved downward, sharply glandular-serrate with incurved teeth, 
bronze red as they unfold and coated on the upper surface with soft 
pale appressed hairs, at maturity membranaceous, glabrous, dark yel- 
low-green above, paler below, 2 to 3 in. long and 4 to 2 in. wide, with 
slender midribs and veins running to the tips of the lobes ; petioles 
slender, nearly terete, glandular with minute dark glands, often dark 
red, from 1 to 1j in. in length. Flowers 3 in. in diameter in broad 
loose many-flowered thin-branched glabrous cymes;  bracts and 
bractlets linear-lanceolate to oblanceolate, coarsely glandular-serrate, 
light red; calyx narrowly obconic, glabrous, the lobes linear-lanceo- 
late, long-pointed, entire, tipped with bright red glands, reflexed 
after anthesis ; stamens usually 10; filaments slender, elongated ; 
anthers small, rose-color; styles 3 OF 4, surrounded at the base by a 
thin ring of pale tomentum. Fruit in loose large pendulous clusters, 
oblong or obovate, bright scarlet, very lustrous, about $ in. long and 
ġ in. thick; calyx cavity deep and narrow, the lobes elongated, 
reflexed and closely appressed, usually persistent; flesh thin, dry 
and mealy; nutlets usually 2 or 3, prominently ridged on the back, 
1 in. long. 
A broad shrub often ro or 12 feet high with many stout intricately 
branched stems and slender chestnut or orange-brown lustrous 
branchlets marked with pale lenticels, becoming ashy gray during 
their second season, sometimes nearly unarmed but usually furnished 
with stout straight or slightly curved spines from r to 2 in. in length. 
Flowers at the end of May. Fruit ripens after the middle of Sep- 
tember and remains on the branches for several weeks, falling 
gradually. 
The common thin-leaved species of the Atlantic coast from Massa- 
chusetts Bay to Nova Scotia and not rare in northern New Hamp- 
shire, in the Champlain Valley and in the neighborhood of Montreal. 
Well distinguished from the other thin-leaved species, with 10 sta- 
mens and rose-colored or pink anthers, by the sharp usually deep 
lobing of the leaves. "This plant is cultivated in England as Cratae- 
gus coccinea indentata, Loudon, but Loudon’s figure of his variety of
