152 Prof. Buckman on Cnicus tuberosus. 



this I stated in an account I sent to the 'Phytologist/ and which 

 appeared in the September Number of that Journal for 1856." 

 For the present, then, I must content myself with having 

 offered presumptive evidence of the non-specific character of 

 what is, after all, a decidedly distinctive form ; and as I have 

 brought home some specimens and planted them in my botanical 

 garden, where I shall also introduce the acaulis and acanthoides, 

 I shall look forward to the results of experiments with these with 

 no little degree of interest, as in all probability, like so many 

 other experiments which I have been enabled to perform in the 

 same direction, these may serve still more to perplex the question 

 " What is a species ?" 

 Cirencester, July 1857.
