Characteristics

Rhizomatous perennial herb forming loosely tufted mats up to c. 60 cm across, flowering stems up to c. 80 cm tall, simple below the inflorescences, slender, woody, glabrous, closely leafy becoming bracteate upwards. Lower leaves up to 7.5 x 2 cm, more or less spathulate, expanded part up to c. 4 cm long, elliptic, apex subacute, margins thickened, callose-crenulate or denticulate, contracted below into a broad (up to c. 4 mm) flat, petiole-like half-clasping base, margins here thickened, entire, coriaceous, glabrous, somewhat glaucous, becoming less distinctly contracted to the base upwards, then oblong-lanceolate to lanceolate passing into distant lanceolate-acuminate bracts. Heads minutely and inconspicuously radiate, terminal, solitary or several corymbosely arranged on long sparsely bracteate peduncles. Involucre turbinate-campanulate, bracts 12-14, 8-10 mm long, a little shorter than the disc, calyculus bracts few, descending on the peduncle, all with 3-5 orange-coloured resinous nerves. Rays c. 13, very short, equalling the disc flowers, corolla lobes of disc flowers each with a median orange-coloured line running to the base of the tube, all very pale yellow, style branches tipped with a short cone. Achenes c. 4 mm long, cylindric, ribbed, orange oil-filled striae between the ribs, glabrous.
