Flowers in long-pedunculate axillary and terminal diachasial cymes, these sometimes congested and subcapitate, often forming a large lax, panicle-like inflorescence or, sometimes, appearing in the form of a lax raceme; bracts leaf-like, linear to oblong, diminishing in size upwards; peduncles 1-9 cm long; bracteoles 5-7 mm, linear, pedicels 0-10 mm; outer sepals 7-8 × 4-5 mm, lanceolate, acuminate to caudate, densely pilose, the lower half colourless, the apical portion green, the inner sepals slightly broader, ovate; corolla 1.7-2.5 cm long, pink, unlobed, midpetaline bands pilose, darker; ovary pilose, style pilose, divided c. 4 mm above base, stigmas 3 mm.
