definite station, Sullivani; North Carolina, without definite station, specimen in 
the Lindenberg herbarium at Vienna. The reasons for discarding the name P. 
allegheniensis and for reserving the name P. Sullivantii for the species represented 
by Sullivant’s Muse. Alleg. No. 219 have been stated by the writer in another 
connection. 1 For a figure of P. Sullivantii see Evans, Bot. Gazette 21 : pi. 15, 
f. iq. 1896. 
3. Cepiialozia Francisci (Hook.) Dumort. 
The geographical distribution of this rare species in North America is so 
incompletely known that the report of the following new stations seems justifi- 
able: on moist soil in barren, mountains west of Ingonish, Cape Breton Island, 
Nova Scotia, G. E. Nichols (No. 813B); Southold and Orient Point, Long Island, 
New York, R. Latham. The last two stations, which represent a marked exten- 
sion of the known range to the southward, are of especial interest and indicate 
that the plant ought to be looked for in eastern Connecticut and Rhode Island. 
In 1912 the writer 2 cited three stations for C. Francisci from Nova Scotia and 
Maine, no others being known from North America at that time and in 1913 Miss 
Lorenz discovered it in New Hampshire, 3 so that seven localities in all have now 
been reported. 
4. Cephalozia leucantha Spruce. 
The range of this minute species in North America is still very incompletely 
known. It was first collected at Columbia Fiord, Alaska, by Coville and Kearney, 
while members of the Harriman Alaska Expedition, and a full account of the 
plant, with figures, was drawn up from their specimens by the writer. 4 It has 
since been reported from Hunker Creek, Yukon, J. Macoun ; 5 from Port Ren- 
frew, Vancouver Island, British Columbia, Miss Gibbs, S. A. Skinner ; 6 and from 
Port Chatham, Alaska, G. B. Rigg. 7 It is now possible to add the following 
stations for the species: Bay of Islands, Newfoundland, 1901, Howe & Lang 
(No. 1077) in part ; valley of the Barrasois River, Cape Breton Island, Nova Scotia, 
1914, G. E. Nichols (No. 575) ; Douglas, Alaska, 1908, Miss Clark (Nos. 7, 13) ; Uclu- 
clet, British Columbia, 1909, J. Macoun (No. 53); Westport, Washington, 1908, 
A. S. Foster (No. 766). It will be noted that some of these localities extend 
the known range of the species far to the eastward and considerably to the south- 
ward in the Pacific Coast region. At lower latitudes the plant grows on rotten 
logs, often in company with other species of Cephalozia; at higher latitudes it 
is more frequently met with in bogs. 
5. Hygrobiella laxifolia (Hook.) Spruce. 
Collected in 1914, at Smith’s (North) Brook, Cape Breton Island, Nova 
Scotia, on flat rocks along a stream in a ravine, by G. E. Nichols (No. 629).
