Plants to 18 cm long, sparsely-branched vegetatively, differentiated into distinct vegetative and flowering axes. Stems with 8-12 vegetative internodes; basal internode usually terete or slightly angular, 2-3 mm long, 2-3 mm in diam.; succeeding internodes of the main stems progressively more strongly flattened, the largest ones narrowly to broadly elliptic or rarely almost linear, (10-)15-25 by (3—)6—15 mm; the vegetative branches mostly flattened in the same plane as the parent stem; venation with 3-7 veins distinct and raised and connecting veins usually visible. Rudimentary leaves together encircling the node, c. 0.5 mm high, leathery, acute at the apices. Flower-bearing stems forming terete spike-like conflorescences to 35 mm long, these usually solitary in the axils and sometimes terminal in threes; internodes 1-1.5 mm long; floral bracts c. 0.5 mm long, acute, sparsely and shortly ciliate. Hairs of the floral cushion absent. Flowers in 1 row, 3 per cluster; the male flower solitary and central. Fig. 3c, d.
