Perennial herb, up to 0.9 m high. Stems erect; greyish green stellate-pubescent. Leaves with blade narrowly oblong, 30-100 x 4-20 mm, base and apex rounded, margins shallowly toothed, main vein ending in a sharp point, upper and lower surfaces greyish tomentose. Flowers: epicalyx bracts and calyx lobes narrowly ovate; corolla with petals ± 5 mm long, yellow; Sep.-Feb.
Herb, up to 0.9 m high, much-branched. Epicalyx bracts lanceolate. Mature flower stalk as long as or longer than petiole, 10-40 mm long, 1-3-flowered. Flowers yellow.
Epicalyx bracts lanceolate-acuminate, differing from those of both M. randii and M. prostrata in being about half the length of the sepals.
Peduncles not elongated, as in both the other species, at maturity but shorter than, or only slightly exceeding, the petioles in length.
Leaf-margins usually dentate, especially towards the apex, those of M. randii and M. prostrata being usually quite entire.
Very like the two preceding species and resembling M. randii in having its leaves tomentellous on both sides.
Flowers almost twice the size of those of M. randii, the sepals being c. 1·6 cm. long.
Seeds slightly roughened or tuberculate but scarcely reticulate.
