leafblades 1 to 2 cm. long, sometimes smaller, on vigorous shoots of the season, 
longer, on strong basal sprouts sometimes reaching 3 cm., orbicular in outline, 
truncate to rounded at the base, 3-lobed, each lobe with a few rounded teeth, 
sparingly pubescent or nearly glabrous on both surfaces; peduncles 5 to 12 mm. 
long, pubescent and usually with scattered longer gland-tipped hairs, one- 
flowered or occasionally two-flowered; bracts usually 2, pubescent, entire; 
pedicels 1 to 5 mm. long, densely pubescent and often with scattered gland- 
tipped hairs like those of the ovary; flower 15 to 20 mm. in length, green to 
greenish white; ovary densely clothed with stout bristly hairs tipped with cup¬ 
shaped glands; calyx tube green, pubescent on the outside, sparingly pubescent 
on the inside toward the base, cylindrical, 3 to 4 mm. long, the lobes green 
to greenish white, linear, pubescent on the outside, glabrous on the inside, 
reflexed, 4 to 6 mm. long; petals about 2 mm. long, greenish white to green, 
each inrolled into a truncate tube with a spreading or revolute rim at the sum¬ 
mit; stamens extending nearly 1 cm. beyond the petals; filaments greenish white 
to green, usually sparingly hairy; anthers purple, about 1.5 mm. long when dry, 
sometimes 2.5 mm. long when fresh, usually with a line of long white hairs (or 
occasionally a green and gland-tipped hair) on the back between the anther sacs; 
styles green, a little longer than the stamens, very sparingly hairy within, as 
well as beyond, the calyx tube; largest berry, not yet mature, 22 mm. long, 
22 mm. broad, including the prickles, the body 16 mm. in length, 12 mm. in 
thickness, translucent, uncolored; 2 fruit prickles very numerous, vivid green, 
somewhat flattened, longer toward the middle of the berry than at the ends, 
reaching a length of 5 mm., the larger nearly 1 mm. wide at the base, each 
ending in a green cup-shaped gland. (See PI. 1.) 
Type specimen No. 1,112,807, United States National Herbarium, collected 
March 2, 1924, a few hundred yards south of Dogwood Landing, east shore of 
the northwest arm of Lake Miccosukee, Jefferson County, Florida, by Frederick 
V. Coville. 
In the somber surroundings of gray tree trunks, gray Spanish-moss ( Den - 
dropogon usneoides ), and gray-brown leaf litter, the patches of this plant were 
conspicuous for the brilliant green of their new foliage. The only other shrub 
conspicuously green at the time the gooseberry came into bloom was red 
buckeye, Aesculus pavia , which also was in full leaf and nearly ready to flower. 
Although its stems are viciously spiny, the new Grossularia when in bloom is of 
graceful and pleasing appearance, the slender, elegant, pale green flowers 
hanging down singly from the broadly arching branches like aquamarines 
pendent from an emerald necklace. 
The new species differs from its nearest relative, Grossularia curvata , in the 
white or whitish color of the 1-year-old twigs; the ovary densely clothed with 
stout gland-tipped hairs; the cylindrical, pubescent calyx tube 3 to 4 mm. in 
length and longer than broad; the green or greenish color of the calyx lobes; 
the inrolled tubular character of the petals; and the spiny fruit, which looks 
like a cocklebur, especially like the fruit of Xanthium globosum . In Grossularia 
curvata the 1-year-old twigs are dark reddish brown; the ovary bears sessile glands; 
the calyx tube is saucer-shaped, hardly more than a millimeter in length, much 
broader than long, and smooth or nearly so; the calyx lobes white; petals ex¬ 
panded and toothed; and fruit smooth. In the new species the filaments and 
style are only very sparingly hairy, in curvata densely and conspicuously hairy. 
* Berries collected by Doctor Harper on May 10, though still hard, green, and unripe, had reached the 
astonishing diameter of 30 mm. (over 1% inches), including the spines, and the body of the berry 22 mm. 
(over % of an inch).
