But Rothrock, when he drew up his description, also had a 
third plant in mind, for he cites as a synonym of I. Woljii 
the R. sanguineum var. variegatum of S. Watson in King’s 
Report of the Geological Exploration of the Fortieth Parallel, 
vol. v. p. 100, which most authorities consider to be 
specifically distinct from R. sanguineum. In the Botany 
of California, vol. i. p. 207, Watson adhered to his name, 
and reduced Rothrock’s species. A search in the Kew 
Herbarium brought to light the apparent identity of 
Watson’s plant with R. nevadense, Kellogg in the Pro- 
ceedings of the California Academy of Natural Sciences, 
vol. i. (1855), p. 63, ed. 2 (1873), p. 65, and this view is 
supported by Greene in his Flora Franciscana, p. 198, 
where he cites 2. sanguineum var. varieqatum, S. Wats., as 
Synonymous with Kellogg’s species, but he implies that 
Watson’s name covers more than one plant, for he adds 
“partly.” Weare satisfied that R. mogollonicum, Greene, 
is the same as &. Wolfii, Rothrock, as emended and re- 
stricted by Coville, but we are doubtful as to the 
advisability of rejecting a name now introduced into 
gardens, and about which there is no uncertainty, for one 
which has led to so much confusion. 
The plant from which the accompanying figure was 
prepared was raised from seed received from Mr. H. 
Henkel, of Darmstadt, in 1900. It is now about 2 ft. 
high. Anotber plant, obtained from the Missouri Botanical 
Garden in 1902, is 44 ft. high. It flowers in May. 
In habit RB. mogollonicum closely resembles R. sangut- 
newm, Pursh, and has similar large pink winter-buds. It 
has the odour of the Black Currant (R. nigrum, Linn.). 
The species is a native of the Mogollon Mountains in New 
Mexico, and of several localities in Colorado and Utah. 
Descv.—A robust, unarmed shrub, branched from the 
base ; branches reaching a height of 10 ft., like the branch- 
lets erect or ascending, minutely puberulous on the 
youngest parts. Leaves 5- more rarely 3-lobed, suborbi- 
cular, 1-3 in. across, cordate at the base, sparingly pilose 
on the under side, and sprinkled with sessile glands ; lobes 
broadly ovate or triangular, crenate-serrate or bicrenate- 
serrate; petioles 3-13 in. long. Racemes solitary, arising 
at the apex of very short leafy branchlets, straight, erect, 
or erect-spreading, sprinkled with stalked glands, many-
