ern Quebec and Rupert Land throughout the forested region to 
Alaska, and south to western New England, northern Pennsylvania, 
Michigan, Montana, Idaho and California. 
The third shrub has the small leaves pilose beneath, but, unlike 
those of the other two, decidedly whitened below, the leaves of the 
two preceding shrubs being merely pale green but not white beneath. 
This shrub with the leaves white beneath is known from Lake Supe- 
rior to Lake Winnipeg, and from Alberta to Oregon and Colorado. 
In the summer of 1904 the first-mentioned shrub, with glabrous 
leaves, was found in abundance on a wooded bank at Tadousac in 
eastern Quebec; while on the opposite bank of the River St. Law- 
rence, at Bic, the second shrub, with the green leaves pubescent 
beneath, was abundant. The flowers and other features showed no 
clear differences, but in the pubescent leaves the Bic shrub was strik- 
ingly unlike the smooth-leaved shrub of Tadousac. An attempt to 
identify the two shrubs has brought to light a singular confusion 
which has long prevailed in our interpretation of the plants which 
have passed as Symphoricarpos racemosus. 
The species was described by Michaux from Lake Mistassini, but 
in his original description there is nothing to indicate whether or not 
the leaves are pubescent or glabrous. A pencil-note, however, “leaves 
very tomentulose beneath,” which I made in 1903 while examining 
the herbarium of Michaux at the Muséum d'Histoire Naturelle in 
Paris, indicates that the Michaux type from Lake Mistassini was the 
pubescent leaved shrub which we know to be generally distributed 
in western Quebec and western New England, and which has usually 
passed as Symphoricarpos racemosus, var. pauciflorus. 
The widespread application of the name Symphoricarpos racemosus 
to the glabrous-leaved shrub seems to be due to an erroneous identifi- 
cation of Loddiges in 1818. In the text accompanying the first illus- 
.tration of this glabrous-leaved shrub (as Symphoria racemosa), Lod- 
diges said: “This plant is quite new to this country [England]; we 
received it, for the first time, last spring, from our friend Mr. Robert 
Carr, who informs us that it isa native of the Western country of 
North America, and was found by Lewis and Clark beyond the rocky 
mountains, in August 1805: we consider it, however, to be the 
Symphoria racemosa of Michaux.”!  Loddiges” identification was 
accepted by Sims, in 1821, in the Botanical Magazine, where a col-
