If the starting-point of generic citation date from the pviblication of tho 

 first edition of the Species Plantarum in 1753, the earliest name for this genus 

 is Couringia, which was employed by Adanson in his Families des Plantes in 

 1763. This spelling appears to be a misprint for Conringia, a name given to 

 the above plant by Heister to commemorate Hermann Conring, an eminent, 

 jurisconsult of the previous century. If Adanson's name be disallowed, then 

 the oldest name appears to be Oorinkia, which was used by Presl in 181 9. 



I have no records of the occurrence of C. orientalis in Bxickinghamshire 

 and E. Gloucestershire.
