florum, under which name the plant was taken up by Meyer in his 
Plants of Labrador and by Schlechtendahl in his enumeration of 
Labrador plants. Lange, in his Conspectus of the Flora of Green- 
land, treats the plant as a pronounced geographic variety, calling it 
Chamaenerium angustifolium B. intermedium. This plant certainly 
seems to be more than a dwarf form of E. angustifolium, for, in New- 
foundland and in the Shickshock Mountains of Quebec where it occurs, 
it is found in considerable colonies growing by colonies of the larger 
plant and it seems there to be an entirely distinct variation. Var. 
intermedium, like true E. angustifolium has broad- and narrow-leaved 
forms, the leaves sometimes being extremely slender and linear, in 
other colonies more oblong; and the flowers have either large or small 
petals. 
In the arid regions of western North America, especially through 
the Rocky Mountains of the United States and westward into eastern 
Washington and Nevada, much of the plant called E. angustifolium 
differs from the typical form of the species and from the varieties 
above discussed in having the leaves scarcely attenuate at apex but 
merely acutish or even obtusish, so that in a large series of speci- 
mens the leaves appear pronouncedly unlike those of the more widely 
dispersed plant with long-attenuate leaves. This variation was 
undoubtedly the basis of Chamaenerium angustifolium platyphyllum 
of Daniels, which was described as having the leaves “merely acutish 
at apex,” although the plant upon which Daniels based the variety 
was an extreme one with unusually broad leaves and leafy bracts. 
This Rocky Mountain variant extends eastward locally to Minnesota 
and it is well developed, like many other Rocky Mountain species and 
varieties, in the subalpine region of Gaspé County, Quebec, where it 
is abundant in the meadows and gorges of Table-top Mountain. Like 
the other varieties of the species, var. platyphyllum presents broad- 
or narrow-leaved phases and large- and small-flowered extremes. 
These, however, are not sufficiently defined nor of definite enough 
geographic range to be readily separated. 
Typical E. angustifolium has the petals of the familiar purple or 
magenta color which enlivens the clearings and burns of the northern 
states and Canada. The frequent albino of this typical variety, 
E. angustifolium, forma albiflorum (Dumort.) Haussk., has pale 
whitish-green sepals and white petals. On the Gaspé Peninsula of 
Quebec, where so many phases of the species are found, occurs a very
