Fls (1)-3-18, in pseudoumbels, pendent; peduncles (7)-15-45 cm long, glabrous to sparsely hairy; pedicels to 2 cm long, densely clothed in glandular hairs. Bracts at base of pedicels, c. 2.5 mm long, lanceolate, hairy, with apical calli. Sepals 5-6.5 mm long, lanceolate or oblong-lanceolate, with glandular hairs mainly towards base, or nearly glabrous; calli 2, apical, usually orange, sometimes yellow.
