plant given by Mr. Berkeley, so far as outward resemblance may 

 be trusted. But the magnified figure of that author is very 

 unlike that now given ; nor have I been able to detect the long 

 diaphanous points to the filaments which he describes. Still 

 I am inclined to regard our plants as identical. 



From the common Leathesia tuberiformis [Corynephora marina, 

 Ag. and Brit. EL), L. Berkeleyi differs in being at all times of a 

 dense and solid substance (not, as L. tuberiformis, at first floc- 

 culent within, and then hollow), in its different colour, and more 

 depressed form. In all the essential characters, if my analysis, made 

 from the recent plant, may be depended on, the two plants agree 

 in structure. I therefore remove L. Berkeleyi, which was at 

 first placed in Chatophora, to the present genus. The name Cory- 

 nephora under which these plants have been hitherto known to 

 British botanists must be laid aside, being too like, both in sound 

 and sense, to Corynephorus, Palis., a genus of Grasses; and 

 that now revived was proposed for the typical species in 1821, 

 three years earlier than Agardh applied Corynephora to it.
