three species are included under the above three names I 

 feel unable to say with any confidence ; and as localities 

 both of fusca and of macra have probably been placed on 

 record under the name of militaris, it becomes very difii- 

 cult to show the exact distribution of each one apart fiom 

 the other two. O. fusca is well known to grow in Kent, 

 and the Rev. G. E. Smith marked it also as a plant of 

 West Sussex, in a list of British plants which that accu- 

 rately-observing botanist some yeai's ago obliged me by 

 checking for the counties of Kent and Sussex. The O. 

 macra is said to occur in Kent, Berks, and Oxford. The 

 O. militaris has been recorded in Kent, Berks, Oxford, 

 Bucks, Flertford, and Middlesex ; but the first and last of 

 these six counties will require verification.

Native or Extinct t Sylvestral ? Though formerly 

 found in Kent, by various botanists, this conspicuous sjie- 

 cies has been so often sought unsuccessfully in the same 

 localities of late years, as to lead to an inference that it has 

 become nearly or quite extinct. Whether fovmd in Surrey, 

 at Box Hill, or elsewhere, appeal's much more dubious.
