HYPNACEAE, 337 
n S. chry vas’ the extreme angle or auricle of the lea 
not taal composed of enlarged cells, but slightly within the ae 
(where the leaf aicdiy joins the stem ) there is a small group of 
naa ead cells, not large or very numerous, but quite distinct, and 
ually orange or brown ieee a specific name). 
In S. maculosus there are no enlarged cells, but a rather large 
eroep of small, isodiametsie very dark and opaque cells, occupying 
a great part of the ngle. 
cupr one is a very common moss, and some fairly well 
marked varieties oceur, which I have not tho ught it necessary to 
a 1 
thread-like, usually rather conspicuously hooked at the tips, and the 
leaves generally not very strongly faleate.

Resembles S. singe one in some of the forms of that species, 
usually the more slender ones, and is perhaps never safe to determine 
without microscopical examination. The seta is sometimes, but 
certainly not always longer 
The alar cells under the microscope, as described under S. 
libinad are usually if not always quite distinct; still some 
forms are by no means easy to separate from S. cupressiformis.
