impossible that any doubt should be coserefned. and which is 
sure to be retained so long as the study of nature shall continue

Specimens of this fine moss have been received from Dr. Wal- 
lich by Sir Joseph Banks, to whose liberality I owe those here 
figured. Mr. Brown has in the 12th volume of the’ Linnean 
Transactions written so much and so well upon the structure of 
almost every part of this plant, that I shall refer my readets to 
his paper, observing only, that although in the formation of its 
peristome it is sap unlike any moss I know, yet it has man
