I am indebted to Mr. W. E. Nicholson. This very distinct but 
minute species forms reddish brown patches, which are apt to be 
that is as far as any plant can be said to occur in abundance on 
that bare locality. It forms the highest vegetation in any quantity 
in Britain, there being large patches of it within a few yards of the

SPHENOLOBUS EXSECTUS (Schmid.). This is a much rarer plant 
in Britain than 8S. exsecteformis (Breidl.). The only specimens of

sheltered places. It doubtless occurs in similar localities in other 
parts of Britain.’ The plant of exposed places on stumps or on 
banks has always been S. exsecteformis, but the latter also is found 
in similar places to the former. The two plants are closely allied, 
but I have never found any difficulty in separating them. . 
Lopxocote yiia (Schrad.) var. patuposa Warnst, This 
Moines closely resembles in habit Chiloscyphus polyanthos var. pal- 
from Chiloscyphus by its different under leaves, the terminal in- 
florescence, and usually by the dimorphic leaves, though Chiloscyphus 
has frequently some which are emarginate. In the latter plant, 
ODoNTOCHISMA DENUDATUM Var. ELONGATUM Lindb, This is a 
well-marked deviation from the type, and resembles 0, Sphagni 
in habit. It occurs in e brown spreading masses in marshy 
ground on the hills in Perthshire, with such plants as Hypnum 
rufescens. It can be distinguished from 0. Sphagni by its stellate 
leaf-cells, and by the usual presence, at least in the Scottish speci-
