Characteristics

Twiggy shrublet 0.6-1 m tall; stems woody, terete, grey-brown, at first minutely tomentellous. Leaves shortly petiolate; blade small, ovate, 8-15 x 5-10 mm, bullate-rugose and finely glandular-scabrous above, conspicuously veined and densely glandular-tomentellous beneath, apex obtuse, base truncate, margin crenate, thickened below. Inflorescence evidently coetaneous with the leaves, occasionally simple, usually with 1-3 pairs of branches near the base; terminal male flower-spikes dense, 30-95 mm long, lateral 15-55 mm long; bracts ovate-deltoid, acute, 3-3.5 x 2.5-3 mm, dotted with red sessile glands. Calyx 1.5 mm long, lateral lobes deeply toothed giving the impression of a 5-toothed calyx. Corolla 3 mm long. Disc with 1 lobe developed beyond the infertile ovary. Female flowers not seen, but occasional seeds are formed in the functionally male flowers.
