298 COMPOSITAE 



C. acanthoides, Hud'«. Fl. Angl. ed. 2, ii. 351 (1778), not of Linnaeus. 

 Top, Bot. 242. S^^me, E. B. v. 6, t. 682. Nyman, 414. Fl. Oxf. 175. 

 Native. Viatical. Waysides. Very rare. A. or B. July-August. 

 First certain record. C. tenuijlorus, Dry Sandford, the author, in the 

 Flora of Oxfordshire, 1886. 

 2. Ock. By the roadside close to the hedges on sandy soil in two 

 or thi-ee stations near Dry Sandford and Cothill, but I have not 

 seen it for the last two years. Mr. F. Walker told me he had 

 seen it near Marcham. 

 [3. Pang. About Streatley, PampUn, in Phyt v. (1854) 156. Probably 



an error ; no one else has recorded it from the district.] 

 [4. Kennet. Without locality, in Russell's Cat. 1839. Probably 



a misnomer.] 

 Either this species is rapidly decreasing in the midland counties or 

 the older botanists confused other species with the true plant. See 

 the same remark under A. Absinthium. 



C. pycnocephalus, var. tenuijlorus, is recorded for Hants and Gloucester- 

 shire, but is, I am afraid, extinct in Oxfordshire.

Top. Bot. 241. Syme, E. B. v. 7, t. 683. Nyman, 411. Fl. Oxf. 174. 



Native. Glareal. Waysides, common on chalk downs, calcareous 

 pastures. &c., evincing a partiality for calcareous soils but not 

 absolutely confined to them. B. May-September.
