“ J. exsecta Schmid., Sandy peat bank, Moidart, 15/3/99- 
S. M. Macvicar.” This is Jung, exsectczfonnis Breidler, recently 
published as a species distinct from J. exsecta. Whether per- 
mantly distinct or not, the plants are easily distinguishable in their 
typical forms. The former has much larger leaf cells than the 
latter, and the gemmae, which are usually present on the apical 
leaves, are angular, while in J. exsecta they are elliptical or oblong. 
The characters taken from the gemmae appear to be less constant 
than that of the leaf cell. Typical J. exsecta is a larger plant than 
J. exsectczformis, with the upper part of the stems frequently 
ascending. On the Continent it is stated to prefer stumps, and 
J. exsectczformis to prefer the ground. From the specimens which 
I have examined from Scotland, J. exsectczformis appears to be the 
more frequent of the two, but this may not eventually prove to be 
the case.”— Symers M. Macvicar.
