one there, 1876. Many plants in a field by Tliornbiiry Lane, 

 Egg Buckland, and about half a dozen on an adjoining hedge- 

 bank, 1866 ; a dozen or two on the border of a field and a 

 hedge-bank at Fursdon, in the same neighbourhood, 1878. 

 Eight or nine plants by the lane between Higher Leigham 

 farm-house and Plymbridge, 1872 ; two by Plymbridge Road, 

 1876. 

 i\Ir. "Watson now thinks the above plant, sent him from Common Wood, 



the intermedia of the London Catalogue and of E. B. ed. 3. When he 



published Coinp. Cyh. Brit, he was not satisfied as to the Plymouth 



intermedia being the true plant, similar to the ones from Cheshire and 



Lancashire (p. 484). 

 It begins to flower a little earlier than B. vulgaris. The petals are 



narrower than those of either vulgaris or prcecox.
