Stems erect, rarely ascending, branched above base (occasionally with slender branches near base); branches straight or slightly arcuate. Leaves alternate; blade filiform to narrowly linear, 1-2 mm wide, less than 1 mm wide in herbarium specimens, usually not fleshy, sometimes semi-amplexicaul at base, apex with soft bristle (rarely subspinescent). Inflorescences not interrupted, dense, 1-flowered (rarely 2-3-flowered), often also in axils of proximal leaves and branches, lower ones tightly enclosed in bracts and bracteoles, forming gall-like caducous balls at maturity; bracts alternate, strongly imbricate and appressed at maturity, base not distinctly swollen, apex acuminate into subulate spine. Flowers: bracteoles becoming connate basally and adnate to perianth segments; perianth segments wingless or with narrow, erose wing at maturity, apex acute, weak and flaccid, glabrous; fruiting perianth ca. 2-5 mm diam. 2n = 18.
