' v V E have received this plant from Sir Thomas Cullurrt,
and the Rev. Mr. Hemfted, gathered near Bury and Newmarket,
and alfo from the Lime-kiln hill, near Shouldham in
Norfolk, where (for the nrft time, to our knowledge, in that
county) it was found by the Rev. Mr. Forby. It grows on a
chalk foil, flowering in July.
Root Woody, branched, crooked, whitifh, perennial. Stems
feveral, reclining, 5 or 6 inches high, but little branched, angular
and (trialed, clothed with numerous alternate linear leaves,
all pointing one wav, fomewhat glaucous and fucculent, entire.
The whole herb is deftitute of pubéfcence, but the edges of the
leaves, bradteas, and angles of the Item appear rough under a
microfcope. Flowers in fpikes (moftly branched, and fome-
times fo compound as to form a panicle), folitary, on alternate
flower-ftalks, with 3 bracteae clofe to each flower fhaped like
the leaves, but in the lower part of the fpike one is much larger
than the other two. Calyx funnel-lhaped, the tube very (hort
and open, margin fpreading, 5-lobed; lobes triangular, with
a tooth on each fide near the bafe, very white above, and at
the margin beneath. Stamina 5, oppofite to the calyx-lobes.
Style ereft, equal to the (lamina. Stigma with 2 knobs.
Seed oval, 5-angled, (Iriated, hard', inverted with the permanent
calyx. The herb is fcarcely bitter, a little faltilh.
This without doubt is T. Linophyllum, but when cultivated,
as Linnaeus had it, the whole herb becomes luxuriant, the
fpike panicled and leafy, according to his definition. T. alpi-
num differs from this in having a long tubular calyx; otherwife
they are much alike. The intermediate kind, mentioned in
Withering, we believe to be the proper wild appearance of
Linophyllum.
