It is often a question whether these aberrant plants actually represent 
forms of C. Trichomanis, or whether they may not be worthy of 
specific recognition. ‘The tendency at the present time, as shown by 
the publication of such species as C. sphagnicola, C. suecica and C. 
tenuis, is to adopt the latter view, and it is probable that further segre- 
gations from C. Trichomanis will be made in the near future.

4: 106. 1849.  Martinellia apiculata Lindb.; Lindberg & Arnell, 
Kongl. Svenska Vetensk.-Akad. Handl. 23*: 32. 1889. On log in 
river; Chocorua, New Hampshire, August, 1906 (W. G. Farlow). 
This rare species was originally collected by Spruce on the French 
side of the Pyrenees, and for many years no other localities were 
reported. At the present time, according to Müller, it is known 
from Norway, Germany, Switzerland and Siberia, as well as from 
France. He also quotes a single North American station, North 
Elba, New York, where Peck? collected the plant less than ten years 
ago. Chocorua is therefore the second locality recorded for North 
America. The species was found, however, by Macoun, as long ago 
as 1881, at Manitoba House, Manitoba, although it is not mentioned 
in his Catalogue of Canadian Plants. S. apiculata is one of the few 
species of the genus which grow on rotten logs. It bears a certain 
resemblance to small forms of S. wmbrosa, which sometimes grows in 
similar localities. In S. apiculata, however, the leaves are entire, and 
their antical lobes spread obliquely instead of being suberect. Both 
lobes are either acute or apiculate. ‘The leaf-cells average about 18 y 
in the middle of the postical lobe and are characterized by distinct 
and often conspicuous trigones. The cuticle is said to vary from 
smooth to minutely verruculose, but the latter condition prevails in 
American specimens. The perianth is entire at the mouth or very 
slightly crenulate from projecting cells. The species frequently re- 
produces by means of gemmae, which present a characteristic appear- 
ance. They occur in dense masses at the tips of leaves which are 
somewhat reduced in size but otherwise scarcely modified. The 
gemmae themselves are oval in form and unicellular, and their walls 
are deeply pigmented with brown or purple. They resemble the 
bicellular gemmae found in Sphenolobus exsectus, but this species may 
be at once distinguished by the smaller and often tooth-like antical
