The genus Anictangium of Hedwig is founded upon the axil- 
Jary situation of the anthers, taken in conjunction with the naked 
mouth of the capsule; characters these, not easily to be discovered, 
and which, according to those species which have been taken into 
that genus by Schwaegrichen, compose a most unnatural assem- 
blage.—Six species out of the ten enumerated by the last-men- 
tioned author, are indeed universally allowed to belong to other 
enera. My friend Dr. Taylor and myself have ventured to pro- 
pose other characters for this genus, taken from the calyptra, in 
conjunction with the insertion of the fruitstalk; and hitherto I 
have every reason to be satisfied with these marks. They have 
certainly the advantage of being more readily discerned than those 
of Hedwig, and the species which they bring together, as far as 
I am yet acquainted with them, do not so greatly recede from one 
another in general habit, as torender the genus an unnatural one. 
The species here under consideration has its fructification very 
ed 
in this work, but from which in its foliage it is abundantly di- 
stinct. Indeed the stems and leaves of H. Hornschuchiana, when 
seen with the naked eye, are more like those of Bartramia Hal- 
leriana than those of any plant I know.
