hairs; their margins wavy, irregularly and rather distantly
denticulato-serrate. Flowers axillary, small, on pedicels not
£ the length of the slender, deeply sulcate, quadrangular ger-
men. Calyx-segments tapering to a point, ^ shorter than the
petals, to which they are appressed and with which they soon
fall off. Petals obcordate with a shallow notch, white at first,
changing to a delicate rose-colour; their veins pellucid and
colourless. Stamens and style much shorter than the petals.
Lobes of the stigma short, sometimes closed, sometimes separated.
Capsule ascending, slender, linear, at length 2-3
incThehse lpolnagn.t is often much tinged with red. The angles of
the stem are very obsolete: a scarcely perceptibly raised line
usually runs down from each edge of the stalks of the stem-
leaves, and a most obscure furrow from their midrib. Towards
the base of the stem the edges of the opposite leaf-stalks sometimes
coalesce at their base and form no decurrent line, as
Fries says is the case with the leaves of his E. purpureum, of
which he regards the “ caulis bifariam sulcatus ” an exclusive
character. From other points however in his description we
dare not quote that plant, of which we have not seen specimens.
E. lanceolatum is very nearly allied to E. roseum (t. 693),
but that plant has a less pubescent or quite naked stem with
two sharp and two blunt angles, broader elliptical leaves with
sunken veins, and more deeply notched petals, the veins of
which are rose-coloured. E. montanum is satisfactorily distinguished
by its round stem, nearly sessile leaves, rounded and
almost cordate at the base, and more deeply lobed and spreading
stigma: its spring rosules too consist of shorter and less
sulcate leaves. So inconspicuous indeed are the angles of the
stem in E. lanceolatum that the Italian authors describe it as
terete; and Mr. Thwaites well observes, that there are varieties
of E. montanum which a not very practised eye might mistake
for E. lanceolatum: such, according to Bertoloni, is the E.
montanum var. lanceolatum of German authors. Bertoloni
mentions a difference which our plants do not show,—that the
capsules of E. lanceolatum are shorter. Italian specimens
gathered by Mr. Woods, who has shown them to Mauri,
differ in no respect from ours, except that a flower remaining
on one of them appears to have been rather larger.—W. B.
