 A luxuriant abnormal specimen from waste ground at Grandpont 

 was sent by the author to the Bot. Exch. Club in 1890. 



The record in [How's] Phyt. Brit, was almost certainly supplied by 

 J. Watlington through Elias Ashmole. In Ashmole's copy of that 

 work in the Bodleian Library the initials J. W. are appended. How's 

 record is repeated in Merrett's Pinax, but a reference to Treacle Worm- 

 seed, Ger. 273 {sic) is added. The plate and the description in Gerard's 

 Herbal point with certainty to the plant being Erysimum cheiranthoides, 

 which is scattered over the county, chiefly occurring in rich soil and 

 more frequently in low-lying localities. It varies considerably in size ; 

 in poor dry soils it may be reduced to two inches, on manure heaps it 

 has been seen nearly three feet high. 

 It occurs in all the bordering counties.
