covered with a blueish bloom. Stems scandent, 3 feet
high, triangular, and occasionally furrowed, rigid, hollow,
about the thickness of a writing quill, becoming woody at
the base. Leaves almost sessile, composed of a single pair of
ovate, mucronate, coriaceous, rigid, 7-nerved, reticulately
veined leaflets, an inch and a halflong, the margins cartilaginous
and somewhat repand ; the younger ones sparingly hairy
beneath. Stipules rather larger than the leaflets, ovate, sagittate,
mucronate, many-nerved, concave above, coriaceous,
rigid, the outer-side more developed; basal articulations large,
callous, of a paler green. Tendrils 3 or 5 inches long, rigid,
semicylindrical, thickened towards the base, with 5 or 7 subulate,
spirally twisted ramifications. Peduncles longer than the
leaves, slightly 5-angular, glaucous, rigid, many-flowered.
Flowers 6 or 7 racemose, singly or in pairs, collected into
two verticils. Bractes very short, membranous, caducous.
Calyx campanulate, ventricose, glabrous, veiny, pale purple
above ; 3 lower teeth lanceolate, acuminate, slightly hairy a t
the apex ; 2 upper ones shorter, broader, ovate, acuminate,
rather connivent. Corolla pale violet; vexillum broad, veiny,
cloven at the top ; wings obovate, connivent, and closing over
the keel to which they adhere ; keel cucullate, obtuse, shorter
than the wings ; claws of the petals linear, white. Stamens
