1891, by Mr. Faxon, in company with Mr. Rand. This number 
agrees with the type not only in structural details, but also in those 
elusive characters of habit which so often give individuality to all the 
material of the same collection. In the present case the identification 
of the Mt. Desert plant as the original source of Warnstorf’s type is 
strongly confirmed by the presence, intermingled with both specimens, 
of the same hepatic, which has been determined by Prof. Evans as 
Lophozia inflata (Huds.) M. A. Howe. It may be mentioned in 
passing, although it must be admitted that in view of the small number 
of botanists who collect hepatics it is at best a doubtful argument in 
favor of Mt. Desert as the type locality of Sphagnum Faxonii, that 
Lophozia inflata has never been reported from Massachusetts. 
As a check upon the accuracy of the data accompanying the speci- 
mens at the Harvard Cryptogamic Herbarium, Mr. Rand’s Mt. 
Desert herbarium was examined, and, as expected, still more of the 
characteristic original material of Sphagnum Faxonii was found, 
again intermingled with Lophozia inflata. Mr. Rand’s herbarium 
afforded, also, two additional stations for the plant on or near Mt. 
Desert,— Great Marsh Heath, Sea Wall and Great Cranberry Isle. 
In two cases the labels gave the habitat as "shallow pools." The 
local use of the word “Heath” on Mt. Desert is explained in the 
introduction to Rand and Redfield’s “Flora of Mt. Desert Island, 
Maine." Here will also be found citation of all the specimens now 
referred to Sphagnum Faxonii, catalogued under vars. plumulosum, 
submersum and falcatum of Sphagnum cuspidatum. 
To determine the relationship of Sphagnum Faxonii with other 
members of the Cuspidata, which occur in the same region, should 
prove an interesting problem to the bryologists of the Josselyn Botani- 
cal Society during their annual meeting at Mt. Desert in August.
