erect or ascending, branched, 5–45 cm, hairy, glandular at least distally, rarely eglandular; small axillary tufts of leaves absent.

prostrate or ascending, tomentose (very rarely subglabrous), hairs white, translucent, long, soft, flexuous, some usually also short and glandular; flowering shoots ascending, 5–20 cm; small axillary tufts of leaves usually absent; nonflowering shoots ± prostrate, to 6 cm.

not marcescent, ± sessile;

blade 5–20(–30) × 2–8(–15) mm, apex apiculate, covered with spreading, white, long hairs;

marcescent or not, sessile;

blade obovate or ovate to elliptic-oblanceolate, elliptic, or lanceolate, usually 10–18 × 5–7 mm, apex obtuse, pubescence as on stems.

3–50-flowered, aggregated into dense, cymose clusters or in more-open dichasia;

bracts: proximal herbaceous, distal lanceolate, apex acute, with long, mainly eglandular hairs.

open, (1–)2–4-flowered cymes;

bracts lanceolate, acute, margins narrow, scarious, glandular-pubescent.
