F O U N D by the Rev. Mr. Relhan on the north fide of
Everfden wood, Cambridgeihire, from whom we received frefli
wild fpecimens Aug. 10,1795. This very rare plant has been
hitherto mifunderltood. The true E. verrucofa of Linnxus is
a perfectly diftindt fpecies, found in the fouth of Europe, with
very hairy involucra and capfules. His friEla, though fo well
defcribed in the 10th edition of Sy/l. Nat. was afterwards omitted
by Linnxus, and confounded (as his herbarium (hews) with
verrucofa. The fpecimen there preferved, being from the Levant,
is more luxuriant than ours, fo that the fecond divifions
of the umbel are moltly three together. The fynonyms of the
verrucofa are in all authors fo exceffively confufed, that we can
anfwer for none but the above. Ray feems (which is feldom
the cafe with him) to have begun the confufion, by taking this
Englilh plant for the Tithymalus verrucofus of John Bauhin, a
fpecies with a creeping root.
Ours appears to be annual, having a very fmall fibrous root.
Whole herb deftitute of hairinefs. Stem fimple, eredt, round,
purplilh. Leaves lanceolate, varying in breadth, entire, and
fomewhat contracted, towards the bafe, ferrated above. General
involucra ovate; partial heart-fhaped; all ferrated.
Petals round, entire, yellow. Germen clothed with tubercles,
which as the fruit ripens become prominent prickles. Styles
permanent, cloven, united half their length into one.
