‘Caules bi- -triunciales, densissime cespitosi, inferne tomento fer- 
rugineo obsiti, superne subramosi. Folia undique imbricata, 
a 
virentia, subpellucida, areolis oblongis reticulata, nervo tenui 
saturatiore ad summum acumen usque percursa. Sef@ unci- 
ales et ultra crassiusculz, pallide flavo- fusca. Capsula (una eum 
operculo) ovata vel oblongo- ovata, oblique sine MOE —— 
fusca, apice pallidiore, “‘nunquam dehiscens, sed una oper- 
culo suo, basi humore et putredine soluto decedens.” "Calyptra 
dimidiata, magna, capsula paulo longior, flavo-fusca, “ capsule 
tam arcte adglutinata, ut in maturitatem usque persistat, et 
non, nisi tempestatum et pluviarum injuriis demum exesa, sol- 
vetur.” 
At the commencement of a second volume, I 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larger stock of unpublished — than when I began the work.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 species from the tropics and _ the 
southern hemisphere, I[ have ni thd the pleasure of receiving 
several new European mosses from Professor Hornschuch, col- 
lected by him in the Tyrolian, Salzburgian and Carinthian Alps ; 
and [ think I cannot better show the value which I 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 rita 
which decays with the capsule, and other marks of less 
ance, taken from what are su to be the male hracphtation, 
which have induced the learned discoverer of this plant (in a me- 
moir entitled “ De Voitia et Systilionovis Muscorum Frondosorum 
Generibus Commentatio,”) to form of it a distinct genus. Should 
ance, Phascum will be thus distinguished : “ Perist. 0. Caps. 
operculo adnata et grange —— (Calyptra brevis fugax.)” 
And P., bryoides will then form a closely connecting link.
