In shady swamps and wet woods, Canada ! and Northern States ! to the
mountains of S. Carolina ! May-June.—Stem extensively prostrate among
mosses &c., with short erect branches, thickly clothed with strong bristles, a
few of which at length become prickles and are more persistent : the petioles
and peduncles are commonly more or less armed with the same rigid bristles.
The leaves are persistent until after those of the succeeding year are
produced. Fruit sour, composed of few large grains.—We have specimens
from Mr. Oakes which are quite intermediate between the ordinary forms of
this species, and the R. setosus of Bigelow.
20. R. trivialis (Michx.) : sarmentose-procumbent, shrubby, armed with
bristles and strong at length uncinate prickles ; leaves (persistent) 3- (or pe-
dately 5-) foliolate ; leaflets ovate-oblong or almost lanceolate, acute (rarely
obtuse and slightly obovate,) sharply serrate, nearly glabrous ; stipules
subulate ; peduncles 1-3-flowered ; flowers large ; petals broadly obovate,
more than twice the length of the reflexed sepals ; fruit large, black.

Pennsylvania? S. Carolina ! to Florida! Louisiana! Arkansas!, and
Texas ! in dry soil. March-May.—The leaves are more coriaceous and
often smaller than in any other N. American species, the young stems very
hispid as well as prickly, the flowers large in proportion, on long hispid or
prickly peduncles. It is very different from the Dew-berry of the Northern
States, which has been called R. trivialis. It ripens its fruit in May, and is
called Low Bush-Blackberry.
21. R. cuneifolius (Pursh) : shrubby, low, armeçl with stout recurved
prickles ; stems mostly erect ; young branches and lower surface of the 3-foli-
olate leaves pubescent-tomentose ; leaflets cuneiform-obovate, rather coriaceous,
with the veins prominent beneath, serrate towards the apex, the margin
revolute near the base ; stipules linear-setaceous ; peduncles few-flowered;
petals obovate (white or rose-color), much longer than the tomentose
oblong mucronate sepals ; fruit ovoid, black.—Pursh ! Jl. 1. p. 347 ; Nutt. !

Sandy woods and fields, Long Island! and New Jersey ! to Florida !
May-June.—Stem 1-3 feet high. Leaves rarely pedately 5-foliolate : the
terminal leaflet petiolulate. Pedicels diverging. Fruit about half an inch
long, ripening in June in the Southern States (farther north in July and August),
juicy and well-flavored. 2
22. R. ursinus (Cham. & Schlecht.) : stem procumbent, terete, aculeate ;
branches, petioles, midrib of the leaflets, and calyx prickly and tomentose ;
leaves 3-foliolate (the uppermost often simple) ; the leaflets broadly ovate,
somewhat petiolulate ; the terminal one subcordate, somewhat lobed, unequally
serrate, hirsute above, tomentose beneath ; stipules linear, small ; peduneles
few-flowered; sepals ovate, mucronate or acuminate, shorter than the
(red, Hook.) petals.—Cham, Sp Schlecht. ! in Linncea, 2. p. 11. R. Men-

Coast, as the specimen of Mr. Menzies in the Banksian herbarium is stated

is a Blackberry, nearest allied, perhaps, to our R. cuneifolius.
™acroPelalus (Dough) : hirsute-pubescent, “ dioecious” ; stem tall,
shrubby; branches and petioles, as also the midrib of the leaflets and the
,wi1th setaceous prickles ; leaves 3-foliolate, the lower ones often
pinnately 5-foliolate; leaflets ovate, incised and serrate, the terminal one rather
distant; stipules lanceolate ; peduncles axillary and terminal, 2-7-flow-

■ Polmie. and m California.—Branches often glaucous. Leaves on the
sarmentose branches often 5-foliolate ; the lower pair distant, conspicuously
pe lolulate, and often 2-lobed. There are two forms, one with the leaflets
mostly acute ; the other (0. mollis, Nutt. R. myriacantha, Dougl.) with the
leaflets mostly obtuse and more pubescent, and the-priekles nearly straight -
the uppermost leaves often simple. Mr. Nuttall remarks that the flowers are
dioecious, or rather dicecio-polygamous. “ The figure of Hooker represents
the sterile plant. In the fertile, the flowers are not half the size, and want the
stamens altogether. The flowering branches are all trifoliolate, and the leaves
e often persistent. The fruit (a blackberry) is cylindric-oval, brownish-
bfack, juicy, and sweeter than our common blackberry (R. villosus).” Nutt.

Calyx urceolate ; the tube contracted a t the mouth, a t length
fleshy or baccate, including the numerous distinct ovaries ; the segments
somewhat spirally imbricated in aestivation. Carpels (ache-
nia) 1-seeded and indehiscent, crustaceous, hairy, with 2 suspended
ovules, one above the other, inserted on the whole inner surface of
the thickened torus or disk which lines the tube of the calyx : styles
terminal or nearly so, somewhat exserted, distinct, or connate above
ra ther persistent.—Shrubby and prickly plants, with pinnate leaves!
rarely reduced to a single leaflet, and mostly adnate stipules.

calyx-segments acuminate or attenuate-cuspidate, entire, or commonly with
