p. 121; species distincta R. nevadensi, Kellogg, proxima, sed racemis 
strictis suberectis, calycis viridescenti-albescentis tubo et segmentis 
brevioribus, petalis late obovatis brevioribus differt. 
Frutex robustus, omnino inermis, e basi ramosus; rami 1°5-3 m. alti, ut ramuli 
erecti vel ascendentes, novellis minute puberulis. olia late 5- (rarius 
3-) lobata, suborbicularia, 2°5-7 cm. diam., basi cordata, basi juxta 
venas parcissime pilosa, glandulis sessilibus conspersa; lobi late ovati 
vel triangulares, crenato- vel bicrenato-serrati; petioli 2-4 cm. longi, 
dense minuteque puberuli. Racemié solitarii, ab apice ramulorum brevis- 
simorum foliatorum orti, stricti, erecti vel erecto-patentes, glandulis 
stipitatis praediti, multi- et confertiflori, 15-3 cm. longi; pedunculi 2°5-3 
em. longi; bracteae elliptico-oblongae vel oblougo-spathulatae, 3-4 mm. 
longae, margine translucidae; pedicelli 15-4 mm. longi. Calycis virides- 
centi-albescentis tubus 1-1'5 mm. longus; segmenta oblonga, 3 mm. longa, 
circiter 2 mm. lata, paulum patentia, obtusa, conspicue paucivenosa. 
Petala alba, late obovato-spathulata vel rhomboideo-obovata, 1°5 mm.

7 mm. diam., glandulis stipitatis parce instructa, edulis.—R. Wolfii, 
Rothrock in American Naturalist, vol. viii. p. 358, partim. 
There is no question as to the identity of our plant with 
R. mogollonicum, but there are difficulties in the way of 
using this name for it. Mrs. Brandegee in Zoe, vol. iv. 
p. 88, appears to have been the first to point out that this 
species is the same as R. Wolfii, Rothrock. Keference to 
the description, however, was not convincing. Inanumber 
of points it is not applicable to £. mogollonicum, especially 
in the red sepals and petals, and the shape of the latter. 
These discrepancies may be explained by Prof. Coville’s 
remarks in the Proceedings of the Biological Society of 
Washington, vol. xiv. p. 1. He discovered that the type 
sheet of &. Wolfii preserved in the National Herbarium, 
Washington, consisted of specimens of two distinct species, 
one represented by flowering specimens which Coville 
proposed to regard as the type of &. Woljii, the other by 
fruiting specimens, which belong to Lv. coloradense, Coville.
