P. calcarea, (Schultz.) "P. amara," (Don.) Specimens obligingly 

 sent me from numerous correspondents, so named from the chalk 

 districts of Wilts, are merely referable to P. vulgaris. I have not 

 gathered the true P. calcarea nearer the county than Cuxton in 

 Kent. It is figured in Engl. Bot. Sitppl. t. 2764.
