Infls paniculate, much-branched, terminal and axillary; branches to nearly 5 cm long, leafy nearly to apex, ± farinose; fls in rather densely crowded glomerules, farinose. Perianth segments c. 1 mm long, imbricate, bluntly keeled on back, green or reddish purple; margins hyaline. Fr. surrounded by perianth except near apex; pericarp tightly adherent.
