Description (by 't Hart & Bleij in IHSP, 2003) :

Glabrous decumbent or prostrate herbs, forming compact ± hemispherical tufts ± 15 cm high.

Leaves alternate or decussate, obovate to spatulate, shortly petiolate, crenate-serrate in the upper part, flat, fleshy, to 4 x 2 cm, obtuse, bright green.

Flowering branches numerous, glabrous, simple, spreading, 10 – 15 cm, reddish below.

Inflorescences compact leafy flat corymbs 4 cm in diameter.

Flowers (sub-) sessile, sepals obtuse, linear, 1/2 as long as the petals, green, petals lanceolate, acute, carinate, bright yellow, filaments spreading, slightly shorter than the petals, yellow, anthers yellow.

The recently described Sedum latiovalifolium is tentatively placed in the synonymy here. It is said to differ from P. ellacombeanus by the broadly ovate leaves arranged in rosettes.
