1 Andres gives a much broader range and cites specimens from Montana, Colorado, 
Utah and Idaho. These plants are certainly not var. americana. In his articles on 
Pyrola (as Pirola) Andres has frequently misinterpreted American plants and Ameri- 
can literature. Thus, for example, he makes an amazing interpretation of a note by 
the present writer. In discussing the absence from Newfoundland of many common 
Canadian species the writer said: “But the distance across Cabot Strait, the short- 
est route from the southwestern mainland to Newfoundland is fully 70 miles, and, 
although this does not seem a forbidding gap, the fact remains that very many com- 
mon Canadian species with fine spores or with the seeds plumose, feathery or other- 
wise adapted for wind-transportation have failed to cross from Cape Breton to south- 
western Newfoundland. Among such species . . . are Lycopodium sabinae- 
folium, Adiantum pedatum, Dryopteris marginalis, Pyrola elliptica and Chimaphila 
umbellata," etc. But Andres's Germanic mind has interpreted this list as an indi- 
cation of the plant association to which Pyrola elliptica belongs; in his monographic 
studies of the genus saying under P. elliptica ‘‘ Begleitpflanzen siehe Fernald. Ex- 
peditions [Expedition] to New-Foundland [Newfoundland]. Rmopona XIII. (1911)

teris] marginalis, Chimophila [Chimaphila| umbellata.” (Andres, Allgem. Bot.
