Rocks, Fuci, and Corallines in the Sea. About Swanfea, freq 



uent. 



THIS fpecies is extremely common on the mores of many parts of South 

 Wales, but has not to my knowledge been obferved elfewhere. It grows indif- 

 ferently on ftones, fuci, and corallines, and often nearly fills the bafons among the 

 rocks, where it may at once be diftinguifhed from its congeners by its light green 

 color and bufhy mode of growth. Its root, a small callus, gives rife to one, two, 

 or more filaments which are from three to fix inches in length and irregularly 

 branched; the branches are difpofed without much apparent order, fometimes 

 dichotomous, or alternate, though not unfrequently three or four iffue fucceflively 

 from the fame fide, they are much curved, and therein this fpecies differs ftrik- 

 ingly from C. rupeftris, the branches of which are remarkable for their ftraitnefs: 

 many together of the ultimate branches are arranged alternately on each fide of 

 the (hoot, and thefe are again beset with ramuli difpofed in the fame order, of 

 which one iffues from the end of nearly every joint. The diffepiments are pellucid 

 and divide the filaments into joints whofe length varies very much in the fame 

 fpecimen, but is always greateft in the principal filament and leaft in the ramuli. 

 No fructification has been yet observed. 



In drying, it preferves its colour, and adheres flightly to paper, but not to glafs.
