Prodr. 504 (1810) APNI
Perennial herb 15–40 cm high, root-suckering and often forming stands to several metres across; branchlets white or greyish with dense simple retrorse hairs, becoming glabrous on angles. Leaves narrowly ovate, 1–2(–5) cm long, 2–6 mm wide, simple, sparsely to moderately pubescent above, densely white-pubescent below, apex sub-acute, margin entire or distantly lobed, usually unevenly recurved and/or undulate; sessile or subsessile. Flowers solitary (rarely 3) in distal leaf-axils; pedicel 5–18 mm long, often horizontal with distal end and flower erect. Calyx (2–)3–6 mm long, densely grey-pubescent with antrorse hairs, tube c. half as long as or equal to lobes; corolla white, tube slightly shorter than calyx, mid-lobe (2–)5–9 mm long, pubescent externally; stamens c.
