Boissier II. 8: 662. 1908. On rotting logs in a cedar bog; Monk- 
ton, Vermont (L. W. Riddle). Not before recorded from North 
America but probably with an extensive range. Widely distributed 
in Europe and northern Asia. Although C. Neesiana has been con- 
sidered a mere form or variety of C. Trichomanis until very lately, 
European writers are now showing a marked tendency to accept it as 
a valid species. It is a robust plant, equalling C. Trichomanis in size, 
and is characterized by oval leaves, rounded or truncate at the apex, 
and by large orbicular or reniform underleaves, usually quite un- 
divided but sometimes emarginate or bluntly bifid to about one fourth, 
these various conditions being often found on a single stem. ‘The 
underleaves are further distinguished by their more or less elongated 
cells with thin walls. Unfortunately, as in other members of this 
difficult genus, many of the slender and sterile stems fail to show the 
characters of the species clearly, but well developed plants are not 
difficult to determine. In a recent paper Meylan' discusses C. 
Neesiana fully and concludes that its characters are much more con- 
stant than those of C. fissa Raddi, which most botanists now recognize 
as a specles; he emphasizes, however, its very close relationship to 
C. Trichomanis.

Lorenz). Although the present plant has been quoted from New 
England this is the only definite station which the writer is able to 
cite. The species is peculiar to North America and its known range 
extends westward to Minnesota and northward into Canada. Its 
most important peculiarities have already been noted in connection 
with the closely related S. apiculata Spruce,’ but it may be well to allude 
to them briefly again. It is characterized especially by its upright 
flagelliform shoots bearing gemmae in abundance. ‘These are oval 
and usually unicellular and are deeply pigmented with brown or purple. 
The leaves upon which the gemmae are borne have thick-walled cells 
without distinct trigones. The normal leaf-cells are much smaller
