FERNALD states (Rhodora 1918, p. 129) that out of 194 
sheets of North American specimens, 188 sheets have quite glabrous 
branches, while in two sheets only the branches bear minute tri- 
chome-like spicules, characteristic of the great bulk of European 
specimens. For the glabrous phase, the name, var. pauciramosum 
MILDE, is given, as this plant in the northern parts of its range 
generally is lesser branched than the type. A f. multiramosum FERN., 
however, occurs also in the southern parts of the American range 
of the glabrous variety. All the plants taken by us belong to the 
glabrous few-branched variety, but a specimen taken by N. Hartz 
Sept. 6th, 1889, at Tassersuaq, Tas. F., is distinctly scabrous and, 
at the same time, “multiramosum’’, 1. e., the typical European form.
