H udson mentions this plant as growing about hedges. It
may in the clothing counties, where it is cultivated for use m
carding woollen cloth, escape from the fields, but we have
never seen it in such a station as to appear really wild. Our^
specimen was taken from Mr. Forster’ s garden at Clapton.
It flowers in July, and is biennial.
Concerning its specific difference from D. sylvestris, 1. 1032,
we think there is much doubt. The leaves are occasionally
■ united or separate at the base in both. The scales which stand
between the flowers in this, are constantly hooked at the
point. The involucral leaves, or general calyx, spread more.
The whole plant has a paler hue. How far repeated cultivation
in rich ground may be capable of producing these differences,
we are not competent to decide. W e are however
much persuaded that D. laciniatus of Linnaeus is only a va-
riety of the plant before us*
