Perennial shrub, dwarf shrub or herb, 0.1-1.5 m high; sparingly to densely pubescent and/or hirsute; stems several, simple or sparingly branched; rootstock woody. Leaves sessile, elliptic-lanceolate or elliptic-oblanceolate, base cuneate or rounded-cuneate, apex subacute, obtuse or attenuate, entire, chartaceous, densely villous on both surfaces at first, later becoming sparingly to evenly pubescent or hirsute. Male fascicles 1-several-flowered; bracts triangular-lanceolate, chaffy. Male flowers: pedicels 1 mm long; sepals oblanceolate-oblong, rounded; petals oblanceolate, rounded. Female flowers solitary; pedicels 2 mm long, stouter than in male; sepals elliptic-lanceolate, subacute, densely fulvous-sericeous; styles suberect-divaricate. Fruit sparingly to evenly pubescent, compressed-ellipsoid, smooth.
Male flowers: pedicels c. 1 mm long; sepals 2.5 × 1 mm, oblanceolate-oblong, rounded, each with a tripartite scale below the middle, and 1–2 subspherical glands at the base, yellowish-green; petals 2 × 1 mm, oblanceolate, rounded, each with 3–5 subspherical glands at and near the base, yellowish, often finely brownish-mottled; staminal column 1.5 mm high, free filaments 0.5 mm long, anthers 0.67 mm long, yellow; pistillode 0.5 mm high, apically expanded.
Female flowers solitary; pedicels 2 mm long, not or only slightly extending in fruit, stouter than in the male; sepals c. 3.5–4 × 1 mm, elliptic-lanceolate, subacute, each with 2–3 clavate glands at the base; petals 3 × 1 mm, oblanceolate-spathulate, subeglandular at the base; ovary c. 2 mm in diameter, densely fulvous-sericeous; styles 1.25 mm long, suberect-divaricate.
Leaf blades 0.5–4(5) × 0.2–2 cm, elliptic-lanceolate or elliptic-oblanceolate, acute, subacute or obtuse at the apex, attenuate, cuneate or rounded-cuneate at the base, entire, chartaceous, densely villous on both surfaces at first, later becoming sparingly to evenly pubescent or hirsute; lateral nerves in 3–5(6) pairs, looped.
A perennial herb 30–90(120) cm high, sparingly to densely pubescent and/or hirsute, dioecious; stems several, simple or sparingly branched, arising from a woody rootstock.
Male fascicles 1–several-flowered; bracts 1 mm long, triangular-lanceolate, chaffy, chestnut-brown.
Stipules absent, or rarely developed and then 1–2 mm long, oblong-lanceolate, subglabrous.
Seeds 3.5 × 2.67 × 2 mm, compressed-ellipsoid, smooth; caruncle 0.5 × 1 mm, creamy-white.
Fruit 5 × 5 mm, sparingly to evenly pubescent, pale green.
Petioles 1–2 mm long, or leaves sessile.
