Stem, shrubby, erect, branching, thickly clothed with a ferruginous
pubescence, consisting of close-pressed hairs, which wear
off by age. Leaves and yrnng branches crowded in our plant. Leaves oblong, or lanceolate, coriaceous, smooth, sinuate, spiny,
reticulately veined, the margins more or less undulate, terminated
with a sharp rigid spine; lower ones broader, flatter, and
blunter, becoming gradually narrower, sharper, and more undulate
upwards. Petioles short and stout, rather shorter than the
stipules, and clothed with a short rusty pubescence. Stipules short, subulate, spine-like, but not very rigid. Flowers of a brilliant
dark blue, tinged with purple, axillary, 2 to 5 in the axil
of each leaf. Pedicles slender, more than double the length of
the petioles, clothed with a ferruginous pubescence. Bractes 2,
spine-like, at the base of the calyx, similar to the stipules. Calyx
2-lipped, thickly clothed with long villous hairs, and short ferruginous
pubescence underneath: upper lip obcordate, keeled, pressculi*
