A siujjle plant found by the Rev. G. E. Smith between the Needles hotel 

 (Groves's) and Alum bay, with a dried portion of which he has since kindly pre- 

 sented me. The specimen, which I presume to be identical with the plant 

 first noticed at Frant, near Tunbridge Wells, Mr. Smith considers, with rea- 

 son, as a casual hybrid between C. palustiis and C. arvensis.
