on the southern shores of England and the Channel Islands it seems to 

 be common. We have received finely fruited specimens from Mr. Albert 

 Hamburgh, Isle of Wight; and from the Rev. J. Yuil, of Peterhead. 



The fruit seems to be generally produced in greater or less plenty, as 

 we have not seen any specimens without it, and is very characteristic of 

 the species, without whicli it may generally be known by its more 

 regularly opposite, not quaternate branching ; the uj)per pinnules fewer, 

 and often defective. 



Professor Harvey, however, considers it not unlikely that more than 

 one species may be included under the present, as he has observed con- 

 siderable diversity in the ramification. We have not seen any of these 

 aberrant forms, but believe the same observation might be very justly 

 applied to several other species of the genus ; not, however, for the 

 purpose of creating species, but of evolving the causes Avhich influence 

 their variations.
