late expansions, acute to obtuse at the apex and quite entire except 
for the small basal stylus. Explanate lobules also occur with con- 
siderable frequency in F. inflata, although many stems fail to produce 
them altogether. The most important distinction between F. inflata 
and F. saxicola is found in the beak of the perianth. In F. inflata the 
beak is short but plainly tubular, the mouth is entire, and the inner 
surface is perfectly smooth. In F. saxicola the beak is still. shorter 
and often cup-shaped, the margin is setulose from cells which project 
in the form of rounded papillae, and similar papillae arise from the 
inner surface, thus blocking up the opening. An approach to the 
condition found in F. saxicola is shown by F. Kunzei and by the three 
other members of the subgenus Diastoloba which are known from the 
United States. In these species, however, the papillae are restricted 
to the mouth of the beak and the inner surface is perfectly smooth. 
A new species very similar to F. saxicola was recently described by 
Schiffner ! under the name F. cleistostoma Schiffn. & Wollny. "This 
plant also grows on rocks and is known at present from only two 
localities, both of them in the Tirol. It shares with F. saxicola the 
important characters listed above in connection with F. inflata, and 
the beak of the perianth is papillate in precisely the same way. No 
specimens of F. cleistostoma have been seen by the writer, but two 
points of distinction have been made out from the study of the pub- 
lished description and figures. In F. cleistostoma the median leaf- 
cells measure 26-30 u, and the involucral bracteole is bifid only one 
fourth; in F. saxicola the median leaf-cells measure only 18-23 y, and 
the bracteole is usually bifid one third or more. Whether these 
differences are sufficient to separate the two plants is doubtful, but the 
comparison of specimens would probably bring to light other points 
of distinction. 
The additions to local state floras not alluded to in the preceding 
pages are as follows: — 
For Maine. Diplophylleia apiculata; Industry (J. F. Collins). 
For New Hampshire. Pellia Neesiana and Cephaloziella elachista; 
Waterville (Miss Lorenz)?

? Some of the records for C. elachista may have to be revised in the future. The 
New Hampshire plants, for example, agree closely with Cephalozia striatula C. Jens. 
(Rev. Bryol. 31: 25. 1904), but the distinctions between this species and C. elachista 
are not yet definitely established.
