The anatomy of the Ericales, in the same work, is given by H. E. 
PETERSEN (l. c., p. 107, 1917). Dr. PETERSEN made his sections from 
the KORNERUP plants, labelled by LANGE A. polifolia L., and described 
them in a comparison with what was known about the anatomy of 
A. polifolia in Europe. He probably was not aware that any related 
species might be taken into consideration. PETERSEN found nothing 
in the anatomical features which “would serve to discern”’ arctic speci- 
mens from temperate ones, except that he states repeatedly: that the 
fine pubescence on the lower surface of the Greenland plants does not 
occur in any European plant. The absence of those hairs on specimens

from Arctic Norway might have suggested to the anatomist that he 
had a specific and no ecologic character before him. 
The North American species of Andromeda are described by FER- 
NALD (Rhodora 1903, p. 70—71 and Gray Manual 7. edit. 1908, p. 634— 
35) thus: 
A. polifolia. Low shrub, with elongate creeping base; stem simple or with 
ascending branches, 5—30cm. high; leaves linear to narrowly oblong, either flat or 
revolute, glabrous, generally whitened beneath with a varnish-like coat, later often 
green; bud-scales scarcely glaucous; pedicels in terminal umbels, filiform, straightish 
2—4 times exceeding the nodding flower and erect fruit; corolla pink or white; calyx 
with pale or usually reddish slightly ascending lobes; capsule brown or reddish, 
obovoid or subglobose, as high as broad. 
A. glaucophylla Link. Similar in habit; leaves white beneath with close 
fine pubescence; branchlets and bud-scales glaucous; flowers on thickish curved pedicels 
rarely twice their length; calyx-lobes whitish, usually spreading; capsule depressed, 
turban-shaped, glaucous. 
The Greenland specimens of A. polifolia L. have all leading charac- 
ters in common with the description above, but the plants are very 
small. The stems are freely branching in the mosses or humus of decayed
