Leaves distichous, ovate-acuminate, abruptly narrowed into a short, broad, open, ciliate sheath, c. 25-40 x 15-20 mm, often with white and purple stripes, purple below. Flowers in pairs of few-flowered cymes, terminal and/or terminating abbreviated side branches; each pair of cymes subtended by 2 leaf-like subequal bracts, pedicels c. 10 mm. Sepals ovate-acuminate, with a ciliate keel, c. 6 mm long, green. Petals ovate, c. 8 mm long, white. Stamens 6, with filaments c. 8 mm long, bearing long beaded hairs in lower half; anthers with an obtriangular connective, locules spreading outwards towards apex. Ovary 3-locular, oblong-globose, with 2 ovules in each locule; style terete or somewhat swollen in middle, stigma capitate. Capsule 2 mm long, chartaceous; seeds reticulate, hilum linear.
