Inflorescences (as seen) solitary in the leaf axils; axis 2-3 mm thick, usually with 2 or more triad-bearing nodes crowded closely above the first; first internode (l0)-l5-20 mm long; second internode 4-10 mm long; third internode 1-4 mm long; triads 8-12 at the first node, 8-10 at the second node, (4)-6-8-(l0) at the third node; peduncles of the triads 5-8 mm long, 1-1.5 mm thick pedicels of the lateral flowers of the triads 2 mm long; bracts spreading, narrow, acute, 1 mm long. Calyx cylindrical, 3 mm long; limb truncate, 0.5 mm long. Corolla in the mature bud (25)-30-36 mm long; petals in the open flower 6, each with a deflexed spur inside (3)-6 mm above the base.
