NONIS PY 
1907] Fernald,— Ribes vulgare 3 
The shrub with the leaves whitened and permanently tomentose 
beneath is the plant described by Pallas from northern Asia as Ribes 
triste, and later redescribed by Maximowicz as Ribes rubrum, y sub- 
glandulosum, from Siberia, Mandshuria and the colder regions of 
America. ‘The other, with the mature leaves glabrous or at most 
ciliate along the nerves beneath and green on both surfaces, is well 
matched by Michaux's material of his R. albinervium described from 
Canada (“ad amnem Mistassin”). The characteristics and distribu- 
tion in eastern America of the smooth-fruited red currents may be 
briefly stated as follows:— 
RIBES VULGARE Lam.  Suberect shrub: leaves mostly cordate, 
slightly pubescent beneath or glabrate; the mature blades 3.5 to 6.5 
em. broad, broadened upwards, 3-5-lobed, the lobes mostly short- 
ovate: racemes spreading in anthesis, drooping in fruit, 3 to 5 (be- 
coming 7) em. long: the rachis glabrous, though often glandular: the 
pedicels mostly glandless: calyx yellow-green; its segments oval and 
abruptly narrowed below the middle: petals narrowly cuneate: disk 
between the stamens and the slightly-cleft style a high narrow ring 
with round-scalloped margin: fruit plump and juicy.— Encyc. iii. 
47 (1789); Janczewski, Compt. rend. acad. franç., cxxx. (1890) 
588, and Bull. Acad. Cracovie, Janv., 1906, 3. R. rubrum, var. 
sativum Reichb. Fl. Excurs. 562 (1830). R. rubrum, most authors, 
not L. Common in cultivation and frequently escaped and estab- 
lished in fence-rows, thickets and open woods.  Naturalized from 
Europe. 
R. TRISTE Pallas. Straggling or reclining, the branches often root- 
ing freely: leaves somewhat heart-shaped, the mature blades 5 to 10 
em. broad, the sides nearly parallel, the lobes mostly broad-deltoid, 
permanently white-tomentose beneath: racemes drooping, 3.5 to 9 em. 
long: pedicels mostly glandular: calyx smoke-color to purplish; the 
segments broadly cuneate or subrhombic, as broad as or broader than 
long: petals broadly cuneate: disk a low broad pentagon: style deeply 
cleft: fruit mostly small and hard.— Pall. in Nov. Act. Acad. Petrop. 
x. (1797) 378); Janczewski, Bull. Acad. Cracovie, Janv., 1906, 3. R. 
rubrum of many authors, not L. R. rubrum, var. subglandulosum 
Maxim. Bull. Acad. St. Petersb. xix. 261 (1874). Cold woods, 
swamps, and subalpine regions, Newfoundland to Alaska, south to 
Maine and Vermont, perhaps confined to regions of pronouncedly 
calcareous soil. Also in Siberia and Mandchuria.
