tranfverfal bands frequently appear; in fome cafes however, as at B, &c. this 

 line is either entirely wanting, or has efcaped the power of my glafs. 



C. flocculofa is fubject to fome variations, of which all that have hitherto 

 been obferved are noticed in the plate. A. reprefents the plant as it generally 

 appears, and indeed though I frequently examined, I faw it in no other ftate for 

 fome months, but on the 23d of May, 1802, my above mentioned friend found it 

 in the New River, as reprefented at B, and he afterwards obligingly communi- 

 cated a drawing of fome that he found varying ftill more from its general ap- 

 pearance, which is given at D. Its favourite fituation is on C. glomerata, which 

 about London is feldom to be met with without it. 



It adheres well to either glafs or paper.
