Information
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.
Habitat
where it occurs in moist submontane grassland, streamsides and marshy localities, at times partly submerged. Under wet conditions it forms extensive mats.
Range
Known only from Mt. Inyangani in Zimbabwe
Distribution
Zimbabwe E Nyanga Distr., Mt. Inyangani, c. 2438 m., 5.ix.1954, Wild 4597 (K; SRGH).
