—— 
The distantly placed branches, the regularly patent leaves, the 
long slender fruitstalks and pale green colour of the whole plant, 
give to this little moss rather an elegant appearance, whence I 
have derived its specific name. In habit it comes nearest to some 
of the straggling varieties of H. prelongum, but in the shape and 
direction of the leaves and their being destitute of a nerve it will | 
be found to approach H. patens, Tas. LVI. of this work. It is 
altogether very different from any other species I am acquainted 
with,
