ROSE—MEXICAN AND CENTRAL AMERICAN PLANTS. 339 
in the general Berlin herbarium seems to be identical with Willdenow’s No. 4860. 
R. jorullense is more recent than R, ¢iliatum and therefore goes properly into 
synonomy. It was retained however in the Biologia Centrali- Americana. 
Ribes mexicanum Spreng. was made because R. multiflorum H. B. K. was found to 
be ahomonym. &. kunthii, however, has a priority of one year, and therefore Lf. 
mevicanin becomes a synonym of that species. 
Ribes multiforum HH. B. K. is a very peculiar species. In the type specimen, our 
only source of information, the inflorescence seems to be abnormal, having the two 
bractlets alternate and distant from the summit of the pedicels and the raceme itself 
compounded. Its flowers suggest ft. affine, but besides differences in the inflores- 
cence the petioles have stalked glands. If it is a good species it must take the name 
R. kunthii, otherwise it must be considered an aberrant form of FR. affine. 
Ribes orizabae Rose, sp. nov. 
Leaves 2 to 4em. long, ovate in outline, 3-lobed, or sometimes 5-lobed, the central 
lobes usually longer, acute, glabrous above but with sessile glands when young, 
pubescent on the veins beneath and with some sessile glands, the margins with 
gland-tipped hairs, doubly serrate; petiole 1 to 2.5 cm. long, with scanty soft 
pubescence and subsessile glands, its stipular base considerably enlarged and ciliate 
with long glandular hairs; racemes drooping, many-flowered; bracts about the 
length of the pedicels, lanceolate, linear, the margins fringed with simple and 
glandular hairs, the lower ones toothed; pedicels only slightly pubescent, soon 
glabrate, never glandular; bractlets caducous, not seen; ovary glabrous; calyx 
pubescent without, including the lobes, 6 mm. long, its lobes nearly 4 mm. long and 
obtuse. 
Collected by Fred. Muller at Orizaba in 1853 (no. 6872). Type in Gray her- 
barium, fragment and photograph in United States National Herbarium, This 
specimen belonged to the John Ball herbarium, which went to the Gray herbarium 
in 1890. 
This species differs from /?. affine in having the upper surface of the leaves per-- 
fectly glabrous, the teeth sharper, the margin bearing gland-tipped hairs, the lower 
bracts toothed, the pedicels much less pubescent, the stipular base larger, with longer 
fibrille. If this plant came from near Orizaba City it is found at a much lower 
altitude than the true R. affine. 
Ribes grande Rose, sp. nov. 
A large bush 2 to 3 meters high; first-year branches dark blue, then reddish, or 
very vigorous ones grayish brown, clothed with short soft pubescence and with 
scattered sessile glands, as also the petioles and inflorescence; petioles bearing stalked 
vlands on the stipular base; leaves nearly orbicular in outline, 3 to 5-lobed, the two 
lateral lobes always small or indistinct, all of them rounded at apex, doubly crenate, 
glabrate above, softly pubescent beneath, bearing sessile glands on both surfaces; 
inflorescence either simple or branched; bracts large and fdliaceous, the lower ones 
toothed and much longer than the pedicels, the upper ones entire, all ciliate and 
vlandular; bractlets linear-lanceolate, pubescent and glandular, borne on the pedicel 
above the middle; calyx lobes broad, but longer than the tube, pubescent; petals 
broader than long; ovary glabrous; fruit bluish black. 
Along the roadside above Chalchacomula, Puebla, on the way to Mount Orizaba, 
collected by J. N. Rose, July 24, 1901 (no. 5656). 
This species is perhaps nearest #. affine, but the lobes of the leaves are more 
rounded, the calyx tube longer than its lobes, ete.
