irregularly terminating membrane, is perfectly destitute of 

 teeth, and much contracted ; the frtiitstalk too is short in 

 proportion to the leaves. 



5. ANICTANGIUM. 



GEN. CHAR. Fruitstalks terminal ; mouth of the Cap- 

 sule naked; Calyptra mitriform. (TAB. L) 



Of this genus the only two species (if they be really distinct) 

 have their leaves destitute of a nerve. 



We think the genus Anictangmm may well be confined to 

 those species which have a terminal fructification and a mitri- 

 form calyptra ; while Hedwigia should be appropriated to those 

 which have their fruit lateral. 



1 . A. ciliatum ; leaves ovate, much lengthened out and diapha- 



nous at the points ; those of the perichaetium laciniated at 

 their extremity. (TAB. VI.)

 We fear that future observations will induce botanists to 



unite the two plants now described, their only difference 



being in the points of the leaves, but especially in the pe- 



richostial ones.
