F o u n d by the Rev. G. R. Leathes in great plenty at Hun-
nington, Suffolk, in the middle of May last, also in a field
of tares at Pakenham. We have often met with it, and have
always judged it a variety of L . purpureum, t. 769; but an
observation of Mr. J. D. Sowerby, that the tube of the corolla
in purpureum is furnished internally near the base with a dense
row of bristly hairs, which are wanting in our present plant,
determines us to separate them, as Dr. Withering, Mr. W oodward
and Professor Willdenow have done. We adopt the
name given by the latter as being rather the best, and, from
the popularity of his work, less likely to cause confusion than
one which has never been followed.
The flowers of this Lamium approach nearer in form and
hue to L . amplexicaule, t. 770, than to t. 769, especially
their marginal teeth, while the leaves more resemble those of
the latter. The plant is usually smaller than either, and like
them annual. The seeds are like those of purpureum, and are
ripened in plenty, so that, though an intermediate species, it
eannot be supposed a hybrid production.
