Perennials; glabrous throughout. Rhizomes (tuberiform, fragile), moniliform, segments oblong, 3–5 mm diam., (fleshy). Stems erect, unbranched, 1–3.5 dm. Rhizomal leaves palmately compound (biternate), 7–20 cm, leaflets petiolulate; petiole 4–13 cm; lateral leaflets similar to terminal, blade sometimes smaller; terminal leaflet (petiolule 1–3(–4) cm), blade ternately or pinnately lobed, (distal segment) linear, 0.7–3.5 cm × 0.6–3 mm, base attenuate to cuneate, margins entire (apiculate). Cauline leaves (2 or) 3, palmately compound (biternate, similar to rhizomal leaves, alternate to subopposite), petiolate, leaflets petiolulate; petiole (0.5–)1–4(–5.5) cm, base not auriculate; lateral leaflets similar to terminal; terminal leaflet (petiolule (0.3–)0.7–1.5(–2.5) cm), blade (ternate, distal segment) linear, (0.4–)1.5–5(–6.5) cm × 0.7–4(–6) mm, base cuneate to attenuate, margins entire. Racemes ebracteate. Fruiting pedicels ascending to divaricate, 10–25(–35) mm.
