Synonymy: Not Applicable

Common name: None

Description:
Compact herb 3-7 cm high; stem regularly cymose-branched, glabrous; leaves subamplexicaul, linear and entire or rarely dilated near the apex with a single lateral lobe, acute, 1-3.5 cm long, to 1.5 mm wide, subterete, succulent, glabrous, green.

Capitula borne at successive levels, the uppermost overtopped by the leaves, the others in the dichotomous forks of branches, 4-5 mm diam.; involucral bracts ovate to oblong, 2-3 mm long, ciliolate, with acute incurved apices; female florets 30-55; receptacular scales obovate, apiculate, 2-3 mm long, complicate, straw-coloured.

Achenes c. 1.5 mm long, fawn-villous; pappus bristles 2-3; sterile florets 7-12; corolla c. 1.2 mm long; abortive achene c. 1.5 mm long, straw-coloured; pappus bristles 8-10, very unequal, to 1.4 mm long; receptacle and scales persistent and hardened in fruit, retaining the fertile achenes except for the outermost.
