First record: Blackstone, '1734' (see MS. note in his copy of Johns. 

 Merc. Bot.). It had been previously noticed in Sussex (v. Park. Th. 

 Bot. 620) ; but Blackstone {Spec. 17) thought that Parkinson ' mistook 

 the plant ' there. Since then, however, it has been found in several 

 parts of that county. It has been constantly gathered at Harefield 

 since its first discovery. In 1752, Mr. AV. Watson exhibited specimens 

 collected there to the Eoyal Society. (See Phil. Trans. 47, 428.) We 

 have also seen specimens dated 1819, J. J. Bennett; 1840, H, Kings- 

 ley; 1842, Dr. Bromfield ; 1843, Mr. Htvfny. It still grows there in 

 profusion, amongst wild hyacinths and dog's mercury. E. B. t. 309 

 was drawn from a plant in Dr. Goodenough's garden at Ealing, where 

 it was ' perfectly naturalised.'
