Leaves sessile or very shortly petiolate, 0.6–3 × 0.4–1.3 cm., lanceolate to lanceolate-ovate, shortly narrowed to subcordate at the base, acute to subacute at the apex, moderately to densely furnished on both surfaces with shorter and subappressed to longer and patent hairs.
Much-branched perennial herb 14–36 cm. tall, with a woody, nodose rootstock terminating in a large tuber; stem and branches slender, terete or bluntly quadrangular, more or less densely furnished with long, whitish hairs which may be patent, ascending, or a mixture of both.
Bracts lanceolate, 4–6.5 mm. long, more or less densely furnished with ascending whitish hairs at least centrally, whitish-membranous except for the green midrib, which is excurrent into an arista at least half the length of the lamina.
Inflorescence sessile or almost so on the uppermost pair of leaves, greenish to whitish, shortly oblong-ovoid, (sometimes subglobose on the lowest branches), 1–4.5 × 1–1.4 cm., axis white-pilose.
Ripe utricle oblong-ovoid, c. 3 mm. long, narrowly truncate at the apex; seed c. 2.75 mm. long, oblong-ovoid, yellowish brown, shining, obscurely reticulate or almost smooth.
Stamens 2–2.5 mm. long, filaments glabrous; pseudostaminodes small, oblong to narrowly spathulate, c. 1 mm. long, minutely denticulate with no dorsal scale, quite glabrous.
Bracteoles 5–7.5 mm. long, ovate-lanceolate, indumentum similar, the terminal arista commonly longer.
Ovary obpyriform, c. 1 mm. long, with a faint apical keel; style slender, c. 2 mm. long.
Flowers finally somewhat indurate at the base, not fused to the bracteoles.
Perianth apparently falling without the bracteoles.
