F o u n d in cultivated as well as waste ground, but Ray
thinks it not indigenous, for the reason, we presume, given
in our last page concerning the American Cudweed. I t is
hard to say to what distances such volatile seeds may or may
not be transported by natural means. W e have not met with
this Erigeron near London, as indicated by Ray and Hudson.
A fresh specimen, drawn in the plate, was sent us from the
Ballast hills o f the Northumberland coast by M r. Robson,
and a dry one from (e sandy ground below the bridge at
Neath, Glamorganshire, to all appearance perfectly wild ,’*
by M r . Middleton.

branched in a panicled manner, and bearing very numerous
small yellowish flowers. I t varies from 1 to 2 feet,
or more, in height. Leaves numerous, alternate, lanceolate,
acute, rough-edged, entire, except the lower ones, which are
mostly toothed towards their extremities. Calyx-scales linear
lanceolate, acute, smoothish; at length reflexed. Marginal
florets narrow, erect, whitish, tipped with flame-colour;
those o f the disk white. Seeds white, silky. Dow n rough,
as well as the receptacle.
