with TV. hyperborea; their size and general aspect being
nearly the same : but here the pinnae or leaflets are longer
and narrower, not cordate, more deeply pinnatifid with
more numerous and oblong segments; the stipes is more
chaffy, and the underside of the leaflets, especially at the
midrib and the rachis, are thickly clothed with reddish
chaffy scales; whilst the same parts of W. hyperborea are
sparingly clothed with pale hairs, intermixed, indeed, on
the rachis with a very few broader hairs, or scales. Mr.
Sowerby observes that the capillary segments of the involucre
are not so numerous in W. ilvensis, and the capsules
more spherical.
The specimens, from which our figures are taken, were
communicated from Mr. Wilson’s locality by Mr. Winch.
The only other station yet given for it is Falcon Clints near
Caldron-Snout, Teesdale, where it is found by Mr. James
Backhouse and Mr. J. Hailstone. The two places mentioned
in The English Flora, on the authority of these two
gentlemen, are one and the same.
In Switzerland this plant grows larger than with us; and
from North America we have specimens thrice the size of
our plants.
