we shall find the fruit of Ectocarjpus Litoralis as a 

 thickening of the filaments in bands of darker colour, 

 and striped; whereas the fruit of Uctocajyus Silicu-

 green, striped, tapering to a fine point. 



Ectocaepes jMeete>~sii is a charming little plant 

 gliding into relationship with another tribe, SpJiacel- 

 laria, found at low-water mark on mud and stones : 

 it may be recognized by its pretty fruit, a small pod 

 divided into two chambers by a transparent line, and 

 set in pairs on either side of the ramuli. South coast 

 of England, Ireland, Channel Islands. 



Ectocaepes Geanttlostts is a handsome plant, and 

 is frequent on larger seaweed, dotted abundantly with 

 round fruit, which is quite visible to the naked eye.

 Sericea and Cladopliora : soft, brownish-yellow tufts 

 from one to three inches high, with fruit in pairs, and 

 like dark olive berries, with pellucid border, seated on 

 the ramuli.
