Panicle to 12 cm long, terminal or axillary, slender, terete or slightly compressed; regularly singly, rarely doubly, branched, branchlets short, compact, bearing to 8 +/- secund flowers; bracteoles to 6 by 3 mm, elliptic-oblong, obtuse, shortly sparsely pale buff pubescent. Bud to 7 by 5 mm. broadly ovoid to subglobose, obtuse. Calyx densely pubescent outside, glabrous within; 3 outer lobes deltoid-ovate; 2 inner lobes smaller, broad ovate, acute, thin at base. Petals cream suffused with pink at base, oblong, obtuse, shortly pubescent on parts exposed in bud. Stamens 15, of 3 lengths, the 5 inner about twice length of others; filaments tapering gradually; anther subglobose; appendage to connective short, slender, becoming reflexed.
