130 Flora of Devon and Cornwall, by I. W. N. Keys. 7 
plants it affects. Many of these varieties have been considered as species, 
amongst which three are commonly admitted into the British Flora : — 
O. Picridis, a tall, very pale-coloured variety, growing on the Hawkweed 
Picris ; 0. amethystea, assuming a bluer tint than any of the others, and 
growing on Eryngium " [Babington says on Daucus gummifer, and it is on 
that plant tl^at we find it in Devon and Cornwall] ; " 0. Hederce, not uncom. 
mon on Ivy in the south of England and Ireland as on the Continent. It is 
said to differ from the common form " [i.e. of 0. minor^ " in the yellow, 
not purple colour of the stigma, and other trifling characters, which however 
do not appear to be at all constant."

— D. Common. It is found in every direction about Plymouth, 
so that it is unnecessary to specify particular situations. For seve- 
ral years past two or three fine specimens have shot up their 
straight spikes, densely crowded with flowers, on the garden walls 
of the " Old-church Twelves," in Catherine-street. This en passant, 
and to remind us hereafter (now that these walls are being demo- 
lished to make room for the projected Guildhall) that " such things 
\Yere," and -may I add? — " were most dear to me." Near Wem-
