All round the shores of the Mediterranean, from France east- 
ward to Asia Minor and the Crimea. 
Annual, erect, an inch to three inches high; the stem usually 
furnished with a few short flexuose ascending branches; the 
whole plant glabrous, often, in exposure, tinged with red. Leaves 
close, oblong, obtuse, sessile, ascending, bluntly spurred, one- 
eighth of an inch long, rounded on both faces. Flowers few 
together in lax scorpioid cymes with bracts similar to the leaves 
and scarcely smaller. Pedicels none or very short. Calyx a line 
deep at the flowering time, the deltoid teeth equalling the tube. 
Petals lanceolate, twice as long as the calyx, white tinged with 
red. Inner row of stamens entirely absent, just as in S. rubens 
(Tab. 242). Carpels spreading like a star when mature, scarcely 
exceeding the petals.

———— 
A small annual species of Sedum, quite hardy, and of no other 
than botanical interest. If allowed to sow itself on the rock- 
work it is very liable to be lost, and it is therefore best grown in 
shallow pots, well drained and placed in an airy sunny situation. 
I obtained seeds of this plant, which came from Corsica, from 
my friend Daniel Hanbury, Esq., F.R.S.—W. W.S.
