Inflorescence a subterminal pseudo-umbel of 2-6 irregular flowers, borne on a 2-8 cm long unbranched peduncle; bracts subtending pseudo-umbel broadly ovate, adaxially concave, apices acute, 5-9 mm long and 5-7 mm wide, indumentum as on stem. Pedicel short: 1-3 mm long. Hypanthium 6-11 mm long, indumentum as on stem.
