OF THE GENUS SYMPHYTUM. 515 
the observation made above, that when the setæ are crowded they are not so 
prickle-like as when they are few and scattered. This form is found also in 
other botanic gardens, as there are specimens in the Geneva herbaria which 
were cultivated in the Botanic Gardens of that city and of Paris early in the 
last century. 
S. asperum appears to be much rarer as a naturalized plant in Britain than 
S. peregrinum. The only specimens I have seen which have been gathered 
in recent years were collected by the Rev. H. J. Riddelsdell at Fairford, 
Gloucestershire, in 1908. These are typical examples of the narrow-leaved 
form, with the stem asperous with tubercular setze, subpetiolate upper leaves, 
and small ealyx with oblong obtuse segments.
