CNICUS 301 



C. PAiiUSTRis X ARVENSis I have seen at Ambarrow and Padwortli. At 

 Ambarrow, too, a form occurred with a naked peduncle. In the dry 

 summer of 1893 a pretty form with elegantly cut leaves, and the 

 anthodes collected in a compact terminal inflorescence, occurred in the 

 Wytham meadows [and in the Mnrston fields in Oxfordshire]. 



Grenier & Godron in Flore de France describe a var. torphaceum (under 

 Cirsium) which has naked branches, but I have not observed it in 

 Berkshire. 



C. palustris occurs plentifully in all the bordering counties.
