Leaves nonaromatic; petiole 0.3–0.4 cm; blade linear, narrowly lanceolate, oblong-elliptic, or ovatelanceolate, 3- (occasionally 1-) veined, 1.5–2.5 × 0.4–0.6 cm, 3–many times as long as wide, thick and somewhat fleshy, base cuneate, margins entire, unlobed, apex acuminate, densely white-farinose abaxially, more sparsely farinose adaxially. Inflorescences glomerules in terminal and axillary panicles; glomerules ± densely packed, flowers maturing irregularly; bracts leaflike or absent. Flowers: perianth segments 5, distinct nearly to base; lobes obovate, 0.8–1 mm, apex obtuse, carinate, densely farinose, enclosing fruit at maturity; stamens 5; stigmas 2, 0.1 mm.
