 comital census may possibly be given too high here.

Native. Viatical, &c. The remarks which have been 

 made under Borkhausia fcetida and Crepis biennis, in re- 

 ference to the species now under consideration, will show 

 that its true distribution can only be very imperfectly in- 

 dicated ; several of its localities having doubtless been 

 recorded erroneously for one of the other two plants men- 

 tioned. Mr. C. C. Babington informs me that specimens 

 are preserved in his herbarium, collected in Caernarvon- 

 shire by Mr. J. Roberts. Mr. Forster has stated that he 

 found it in Essex. In common with many other botanists, 

 I have gathered examples in several localities in Kent. 

 And in the year 1839 I found one or two plants in a mea- 

 dow by the Thames towing-path, near Moulsey Lock, in 

 Surrey ; where I have sought it unsuccessfully in after 

 years. Other habitats for the present species have still to 

 be ascertained. Many foreign botanists write the generic 

 name as " Barkhausia."
