Part 3, 1908] GROSSULARIACEAE 215 
A shrub 2 m. high or less, the slender young twigs without bristles; nodal spines sub- 
ulate, rather stout, 1-1.5 cm. long, or sometimes much shorter. Leaves suborbicular in 
outline, usually 5-lobed, sometimes 3-lobed, incisely crenate-dentate, thin, truncate or sub- 
cordate at the base, small, 1.5-3 cm. wide, glabrous or nearly so on both sides, deep-green 
above, paler and nearly or quite smooth beneath, the slender, sparingly glandular-pubes- 
cent or glabrous petiole about as long as the blade, often ciliate at the base; peduncles 1-3- 
flowered, shorter than the leaves, somewhat pubescent and with a few stalked glands, or 
glabrous; bracts ovate to orbicular, shorter than the pedicels; ovary bristly, the shorter 
bristles sometimes glanduliferous ; hypanthium short, broad, cylindric, 2 mm. long or less; 
sepals green or somewhat purplish, narrowly lanceolate, glabrous or occasionally puber- 
ulent, often with a tuft of hairs at the apex, about 6-8 mm. long; petals obovate, erose, about 
2mm. long; stamens equaling the sepals, the filaments more than twice as long as the 
petals; anthers lanceolate, mucronulate, about 2 mm. long; berry densely or sparingly 
prickly, commonly 8-12 mm. in diameter. 
TYPE LOCALITY : California. 
DISTRIBUTION : Middle California.

A shrub 1.5-3 m. high, the spreading branches smooth, without bristles; nodal spines 
stoutly subulate, straight or curved, 1.6 cm. long or less. Leaves thin, suborbicular in out- 
line, 4.5 cm. wide or less, 3-5-lobed, crenate-dentate, mostly truncate at the base, loosely 
puberulent on both sides, paler beneath than above, with minute sessile glands beneath or 
nearly glandless, the slender puberulent petiole as long as the blade or shorter; peduncles 
puberulent, 1-2-flowered, mostly shorter than the petioles, 5-15 mm. long ; bracts flabellate, 
pubescent, ciliate, shorter than the pedicels; ovary densely bristly, a few of the shorter 
bristles sometimes gland-tipped ; hypanthium campanulate, greenish, 2-3 mm. long, puber- 
ulent; sepals greenish or greenish-red, 7-9 mm. long, puberulent, narrowly lanceolate ; 
petals white, tinged with red, cuneate-oblong, 2- or 3-toothed, about half as long as the 
sepals, equaling the filaments or nearly so; anthers oblong-lanceolate, mucronate, about 
2.5 mm. long; berry densely prickly, 1.5 cm. in diameter or less. 
TYPE LOCALITY: Cafions of the San Gabriel Mountains, California. 
DISTRIBUTION: Southern California.

Stems glabrous throughout, or the younger twigs, young petioles, and hypanthium 
puberulent; nodal spines acicular, 1-1.5 cm. long. Leaves, reniform to orbicular, small, 
1-2.5 cm. wide, mostly 3-lobed, crenate-dentate, the slender petioles mostly shorter than 
the blades; flowers solitary or two together, on peduncles usually shorter than the leaves ; 
bracts clasping, veiny, erose, sometimes ciliate, longer than the pedicels ; ovary bristly and 
sometimes with a few stalked glands; hypanthium cylindric-campanulate, crimson, 5-7 
mm. long and about 3 mm. thick; sepals lanceolate, crimson; petals white or pink, in- 
volute, erose or laciniate, about half as long as the sepals, a little shorter than the fila- 
ments ; anthers lanceolate to ovate, about 2.5 mm. long; berry densely spiny. 
Type LOCALITY: California, Coast Range from-Sonoma County northward. 
DISTRIBUTION: Middle California to southern Oregon. Perhaps a glabrate race of the follow-
