Stem shrubby, climbing to a great height, young branches
pubescent. Leaves pinnate, pubescent; the leaflets ovate,
acute, petiolate, 4 or 5 pair; and terminated by an odd one,
the footstalks short and fleshy, downy. Petioles downy,
channelled on the upper side, and rounded on the lower,
swollen at the base, and producing two slender stipule-like
glands at the base of each pair of leaflets. Flowers of a
palish blue, in a close terminal raceme. Bractes large,
acute, pubescent, purple, imbricate, and enclosing the flowers
before expansion, but dropping off" as the flowers expand,
and leaving them naked. Pedicles short and stout, spreading,
pubescent, or thickly clothed with short hairs. Calyx cam-

with short hairs; upper lip short, nearly truncate, toothed
with two very small teeth: lower lip trifid, the laciniae
erect, broadly lanceolate, acute. Vexillum broadly rounded,
lined with innumerable faint lines, eared on each side, blue,
with a greenish yellow spot at the base, above the unguis,
encircled with white; unguis rigid, lined with a rigid plate,
