At the commencement of a second volume, ! find myself, 
through the liberal contribution of my friends, in possession of a 
larger stock of unpublished — than when I began the work. 
In addition to numerous cies from the tropics and the 
southern piney cae just had the pleasure of receiving 
several new European mosses from Professor Hornschuch, col- 
lected by him in the Tyrolian, Salzburgian and Carinthian Alps 3 
and [ think I cannot better show the value which 1 set upon these 
communications, than by hastening to lay them before the public. 
The plant before us is not the least curious among them, having 
the characters hitherto generally ascribed to the genus Phascum, 
but at the same time a large and persistent calyptra, a fruitstalk 
which decays with the capsule, and other marks of less import- 
ance, taken from what are supposed to be the male fructification, 
which have induced the learned discoverer of this plant (in a me- 
moir entitled “ De Voitia et Systilio novis Muscorum Frondosorum 
Generibus Commentatio,’’) to form of it a distinet = Should
