After a critical examination of two sets of Fendler's collection 
from the type locality of Leskea Fendleri, no valid distinction be- 
tween this and Z. collinum could be detected as the setae of P. 
collinum is usually slightly roughened in both European and 
American specimens. Also one capsule of Fendler’s plant had 
two well developed cilia. No specimens of Brachythecium Hille- 
érandi of the original collection have been accessible and all the 
specimens examined which have been referred to this are un- 
doubtedly Æ. collinum. There are no distinctions except the 
shorter capsule, rough seta and simple annulus. The length of 
capsule is always subject to considerable variation 
B. collinum frequently has a rough seta and the terms simple 
and compound, as applied to the annulus, have been used in a very 
loose way.
