glomeratim congefta, t. 5. fig. 31. and which, with the former, are good repre- 

 fentations of this plant. Dr. Roth has united C. glomerata and C. sericea into 

 one fpecies under the name of C. criftata, and I have but little doubt that he has 

 confounded two fpecies, as an authentic fpecimen with which I was favored by 

 my friend Dawfon Turner, is certainly diftincl from glomerata, which he mud 

 have included in his defcription, by his referring to the excellent figure in the 

 Flora Danica. 



Though liable to confiderable variations, as well in the length and thickilefs of 

 the filaments, as in their being fometimes more or lefs branched, yet it may be at 

 firfl fight diftinguifhed from other fpecies, by its beautiful green color, and cha- 

 racteriftic bufh-like ramuli. It is often much infefted with C. flocculofa, which 

 grows parafitically on it, and fometimes nearly covers it. It adheres to both glafs 

 and paper. 



For the drawing I am indebted to my friend Jofeph Woods, jun. F. L. S.- 

 it well reprefents the plant in a rather advanced ftage of growth.
