JP L A N T growing in loosely matted, very pale-coloured
patches. Stems creeping, from half an inch to nearly an
inch in length, filiform, waved, twice or thrice branched in
a dichotomous manner; throwing out from beneath minute
tufts of fibrous radicles. Leaves rather distantly, alternately
and bifariously inserted, very small, so convex as to be nearly
hemispherical, remarkably succulent, with large prominent
cellules, the apex furnished with a single rather deep and
rounded notch, having its segments somewhat connivent.
Their colour is a pale green, becoming still paler and almost
white when dry. The stipules, one between each
pair of leaves, are ovato-lanceolate, quite entire. The calyx
is terminal upon short branches, oblongo-ovate, contracted
and toothed at the mouth. Capsule ovate.
