ntinued; at the same time we must observe, that it ill accords with
that genus: the blossoms while in bud fold up somewhat in the same
manner as those of the Celsia, but on expansion they appear widely
different; their shape indeed then becomes truly singular, resembling a
half-formed imperfect corolla, its filaments are short and want the
hairs which in part characterise the Celsia; its seed-vessels also are
far from being round: its antherae are large and close together, somewhat
like those of the Solanum, and there is so little of inequality in them,
that few students would be induced to refer its flowers to the class
Didynamia.

Being a native of a warm climate, it comes to the greatest perfection
here when placed in a stove in which the heat is moderate; but it will
succeed very well if treated as a tender green-house plant: it does not
appear to be quite so hardy as the Fuchsia, nor to flower like that
plant at all seasons, but usually produces its blossoms in the latter
summer months, those are succeeded by seed-vessels producing perfect
seeds, by which, as well as by cuttings, the plant is propagated.

Its leaves, which are not deciduous, are linear, and more or less
toothed, growing three together; this character however is somewhat
obscured by others growing from their bosoms.

Professor PALLAS, the celebrated Russian naturalist, discovered this
species of Sedum in Siberia, and in the year 1780, introduced it to the
royal garden at Kew; the younger LINNAEUS describes it minutely in his
_Suppl. Plantarum_, and observes, that in its general form it much
resembles the _Saxifraga rotundifolia_.

Its leaves are flat as in many of the other species, and when the plant
grows in an open situation, exposed to the sun, they become as well as
the stalks of a bright red colour, which adds much to its beauty.

It is the only hardy Sedum cultiv
