 Kensington Gardens, abundant, but stunted in growth. 

 First record: Gerarde, 1597. The Kensington Gardens plant was 

 recorded by Smith, Fl. Brit. i. 301, as B. Bulbocastanum, L. on the 

 authority of Mr. W. Wood. In B. G. 402, however, is a note stating 

 that the latter botanist was then ' of opinion the plants he gathered 

 were only large specimens of B. flexuosum^ See also E. Fl. ii. 55. 

 Martyn's Hornsey plant has been often referred to B. Bulbocastanum 

 (see Cyb. Br. i. 436), and we were at first inclined to consider it 

 that species, though all the places at present known to produce it 

 are on a chalk soil, in consequence of some evident care shown in the 

 record. But, from a note by Thomas Martyn in vol. i. (article 



* • A kinde of Besdi growing every-where in the pastures about London,' described in 

 Ger. 894 may be this. Johnson, Ger. em. 1051, says, ' I am ignorant what our author 

 means by this description.'
