Stock slender, multicipital, or the branches elongate, creeping and rooting; lvs scattered along branches and tufted at base of erect peduncles clad in lflike bracts; ± 1-1∙5 cm. × 1 mm., linear, straight to falcate, spreading to recurved, apiculate to subacute, coriac., glab. to sparsely hairy near sheathing base. Peduncles slender, up to c. 2 cm. long in fr. Capitula c. 5 mm. diam.; phyll. 8-14, oblong, obtuse to subacute, c. 3 mm. long, veins often obscure. Florets 10-25; achenes linear-clavate, 4-ribbed on one face, each rib produced into a short appendage.
