Plant slender to moderately robust, pendulous, to 0.6 m long. Stems with rudimentary leaves on each growth segment; internodes terete, 20-60 mm long, 1-3 mm in diam. Leaves mostly rudimentary or sometimes rudimentary and normally developed in successive pairs; normally developed leaves often falling early, narrowly to broadly elliptic, attenuate or cuneate at the base to an obscure petiole 5-10 mm long, attenuate to acuminate and acute at the apex, 5-nerved, with veins visible on both sides, 80-160 by 25-60 mm; rudimentary leaves 0.8-1.5 mm high. Inflorescencess commonly terminal, often in threes, also axillary, often branching near the base, often not strongly differentiated from vegetative stems, 80-200 mm long, a spike of 15-25 pairs of triads; internodes 8-15 (-20) mm long; bracteal cup c. 1 mm long, spreading; bracteoles densely fimbriate, forming a tuft of white hairs surrounding the flowers. Fruit ellipsoid, smooth, white. Fig. 2.
