Characteristics

Shrub or woody herb, much branched, 0.5–3 m. high, densely mealy all over so that the whole plant is whitish to pale grey-green.. Leaves ovate to oblong or elliptic, mostly 1–4 cm. long, 0.4–2.5 (–3) cm. wide, rounded to acute at apex, broadly or narrowly cuneate at base, entire or sometimes with a projecting lateral lobe on each side in lower part.. Inflorescence a terminal panicle with spiciform mostly leafless ultimate branchlets.. Fruiting bracteoles sessile, their basal connate part absent or very short indeed (to 1.5 mm.); free apical part of each bracteole reniform to broadly deltoid-ovate, as broad as or more commonly broader than long, 2.5–6 mm. long, 3–8 mm. wide, acute to rounded at apex, cordate or sometimes truncate or very broadly cuneate at base.
