lo6 SEAWEEDS. 



Edward found a member of this order in Cornwall, which 

 l- called after Desmarest the French botanist ; it is a 

 pretty slender plant with tufts of green hairs along its 

 tapering fronds (Desmarestia Aculeata). There are two 

 other species of the same family, but we found neither 

 of them. In the same order there is a Sporochnus and 

 a Carpomitra, but both are rare even in the south of 

 England
