THE name of C. mufcicola, given to this fpecies in Englifh Botany, having 

 been previoufly beftowed upon a very different plant in Dr. Weber and Dr. 

 Mohr's admirable Swedifh Tour,* and fubfequently in Dr. Roth's Catalecta 

 Botanica, I have been under the neceffity of adopting a new one, and have with 

 the concurrence of Dr. Smith, taken that of C. Orthotrichi, as the plant has at 

 prefent been found upon no other tribe of mofTes. For the fpecimen here 

 figured I am indebted to Mr. Sowerby, to whom it was fent by Mr. Lyell, the only 

 perfon who appears to have yet found it in England, except indeed, as I fufpect, 

 the curled appearance of Orthotrichutn Jlriatum, mentioned in the Mufcologia 

 Hibernica as the variety /3, fhould prove to be the beginning of it. 



C. Orthotrichi grows in very thick entangled tufts on the upper branches of 

 mofTes, having its roots in the leaves and ftem, which it often fo completely 

 covers as to leave fcarcely any part of them vifible. It is of a rich chefnut color,
