The plant here figured is a native of Alaska, where, 
according to Professor Sargent, it grows along the borders 
of upland meadows, opening its flowers in succession during 
several weeks in summer. In addition to C. pyrolaeflorus 
there is, according to Professor Greene, another species of 
Cladothamnus, C. campanulatus, which inhabits the high — 
mountains of British Columbia and Washington, and has 
been confounded with the Alaskan plant. C. campanulatus, 
Greene, is readily distinguished from C. pyrolaeflorus by 
having the petals united in a short tube; the anthers too 
are said to open differently. There is no exampie of this 
species, the characters assigned to which would appear to 
exclude it from the genus, in the herbarium at Kew; the 
only specimen in the collection to which the name 
C. campanulatus is attached is undoubtedly C. pyrolae- 
florus, as indeed are all the specimens at Kew collected in 
British Columbia and Washington. C. pyrolueflorus was 
January, 1911.
