Haplocarpha nervosa

A mat-forming scapose perennial herb, stoloniferous; rootstock woody with numerous thong-like lateral roots. Leaves crowded-rosulate and prostrate, very variable, mostly 3–10 x 1–2.5 cm., exceptionally to c. 21 cm. long or 7.5 cm. wide, elliptic to oblanceolate in outline sometimes elongate-spathulate, gradually or abruptly narrowed from about the middle into a linear petiole-like base, apex subacute to rounded, base cuneate to long-attenuate becoming dilated and ± stem-clasping, margins entire or repand, irregularly toothed, subruncinate or subpinnatifid, midrib broad composed of numerous ± distinct veins running parallel to diverge in pairs at regular intervals, prominent beneath; upper surface glabrous or thinly pilose; lower surface densely white-felted. Scapes several from the rootcrown, up to c. 8 cm. tall but usually shorter than the leaves, simple, glabrous or white-araneose with ± obvious scattered patent soft reddish-purple pilose hairs to c. 1 mm. long. Involucres 8–11(14) x 6–9 mm., broadly obconic; phyllaries few-seriate, narrowly hyaline on the margins, glabrous occasionally pilose outside; outer phyllaries c. 6 mm. long, narrowly ovate, acute to attenuate at the apex; the inner phyllaries up to c. 10 x 3 mm. and oblong-lanceolate, rounded-mucronate at the apex. Ray-florets; rays yellow, spreading, 10–20 x 4–7 mm., narrowly-elliptic, narrowly 3-lobed at the apex; achenes 1–2.5 mm. long, turbinate, obscurely c. 8-ribbed, the ribs transversally rugose or muricate, glabrous except for a short delicate coma; pappus variable, sometimes wanting, 2–3-seriate, of delicate scarious overlapping narrowly lanceolate scales to 1 mm. long, the inner tapering to an attenuate apex, the outer much smaller and blunt. Disk-floret corollas yellow, up to c. 6 mm. long, achenes and pappus similar to those of the ray-florets.
