It is rather variable in degrees of hairiness, &c., but its most marked 

 form is var. Walravenii, Wirtg. Herb. PI. Crit. n. 367==var. maritima, 

 Grisebach, Fl. Eumel. ii. 169 (1844) ; Kops, Fl. Batava, xvii. t. 1352, 

 which was recognized for the first time in Britain by me in some corn- 

 fields on the chalk near Hurley. The history of the variety is described 

 at length in the Journ. Bot. pp. 240-243 (^1894). It is distinguished 

 from the type by the calyx, which in the typical plant has six subulate 

 teeth, while in this variety they are almost effaced and very short and 

 obtuse. Since that time I have seen it in fields at Sulham, Wootton, 

 Hodcott, near Maidenhead, and Cumnor. It also occurs in Oxfordshire 

 at Headington and Forest Hill {J. W. Baker).
