pubescent beneath; male flowers yellow, trumpet-shaped, 4 to 6 cm. long, on 
peduncles 6 to 12 em. long; the lobes obtuse; female flowers somewhat smaller than 
the male flowers on peduncles 3 to 10 mm. long; fruit 4 em. long.

A SYNOPSIS OF THE MEXICAN SPECIES OF RIBES. 
[Continued from page 301. ] 
The following additional notes on Mexican Ribes are based on 
information received too late for incorporation into the body of my 
paper on Ribes: 
Through the kindness of Dr. 1. Urban, I have had an opportunity to examine frag- 
ments from the type material of all of Humboldt’s Mexican species except the 
now well known &. microphyllum. The examination of these specimens in the light 
of the abundant material in the National Herbarium clears up several points which 
have long been misunderstood. The various names based on Humboldt’s material 
will be taken up alphabetically. 
Ribes affine H. B. K. is best represented in our collection by specimens distributed 
by Pringle as &. mudtiflorum and others collected by myself near the type locality. 
In the type specimen the petioles are clothed with soft hairs, and bear a few stalked 
glands on the stipular base only; the calyx tube is very short; the pedicels are with- 
out glands of any kind, but the bracts and bractlets bear stalked glands. None of 
the National Museum material, however, has stalked glands on the bracts and bract- 
lets. A larger series of specimens must yet be collected before the limits of this 
species are Clearly made out. For the reason mentioned below, the reference by the 
Kew Index of this species to R. campaninlatum would not be warranted even if the 
two were the same. 
Ribes campanuatun TH. B. IX. was treated by Kunth as a synonym of his &. affine, 
and has ever since been considered the same as that species. A careful examination 
of Willdenow’s No. 4859, the type of A. campaniuatun H. B. K., seems to indicate 
that this species is the same as my 2. pringlei. The petioles have stalked glands, as 
also the upper surface of the leaf blade; the ovary is glandular, and the flowers were 
apparently large. In all these respects it differs from R. agine and corresponds with 
R. pringlei. The name, however, is a homonym, and therefore does not invalidate 
my new name, An intéresting fact, stated in connection with the original publica- 
tion of KR. campanulatum, which seems to have been overlooked, throws some light 
on this point. Tt is stated that this species was collected with &, ciliaton, which 
came from the State of Michoacan, while if it had been with 2. agine it would have 
come from the central part of the State of Hidalgo. R. ccanpanulatum isa homonym 
of amuch earlier name, as is shown on page 205, 
Ribes ciliahan U1, & B, is well represented in the National Herbarium by Pringle’s 
No, 4255 from the volcano of Toluca. The petiole has short stalked glands and 
short close pubescence; the upper surface is nearly smooth, except for some stalked 
glands, which are also found on the tips of the teeth, while the under surface has 
many sessile glands and much pubescence on the nerves. The material here 
described is a part of Willdenow’s No. 4860, 
Ribes kunthiy Berland, was made because 2. iultiflorwin 1. Ts. ik. was found to be 
a homonym of a much earlier name. If 2. imuitiflorum isa good. species it must bear 
the name of Re henthii, 
Ribes jorullense HW. B. IK. seems to be the same as R. ciliatum. This was the con- 
clusion of Kunth, and 1] believe has never been questioned. Humboldt’s specimen
