Roots perennial, succulent, branching in all directions,
and extending a great way round, when grown in
light soil. Stems milky, numerous, spreading flat on the
ground, and extending to a great length, branching in
all directions ; angular, which is occasioned by the footstalks
of the leaves being decurrent down the stem, roughish,
and more or less tinged with a reddish purple; the
angles a little undulate, particularly near the joints.
Leaves kidney-shaped, emarginate, slightly repand, rather
succulent, smooth on both sides, underneath many
nerved, the nerves branched, the nick terminated in a
short point. Petioles broad, shorter than the peduncles,
flattened, and deeply furrowed on the upper side, and
convex underneath ; roughish, but not pubescent. P e duncles
axillary, solitary, 1-flowered, roundish,or slightly
angular, smooth. Bractes 2, enclosing the calyx, scarcely
as long, cordate, broadly but shallowly emarginate. Calyx
deeply 5-parted, segments broadly ovate, outer ones
