Stem suffrutescent, branching : branches slender, smooth,
somewhat elongated, a little flexuose, sprea.ding, the points
ascending and becoming erect. Leaves sessile, narrowing to
the base, oblongly linear, bluntish, but ending in a very
short sharp point, entire, smooth, succulent, and of a dark
but glaucous colour, generally bent inwards towards the
stem, particularly the points, but sometimes spreading horizontally,
and occasionally a little reflexed. Racemes terminal,
several-flowered, at first corymbose, but as the flowers
drop, lengthened out into a longish raceme. Flowers of a
delicate rosy lilac. Bractes none. Pedicles smooth, slender,
the lower ones rather longest. Calyx of 4 sepals, deciduous,
unequal at the base, 2 being longer and more inflated than
