Revision as of 13:37, 27 July 2019

Roots few, blackish, filiform or somewhat tuberous. Stems erect, not scapose, 15-50(-60) cm, glabrous. Leaves basal and cauline; proximal cauline leaves petiolate, 2-3×-ternately compound; distal cauline leaves sessile or short-petiolate, 2×-ternately compound or simple. Leaf blade: leaflets reniform to obovate, apically 4-7-lobed, 10-30 mm wide, lobe margins crenate, surfaces abaxially glaucous. Inflorescences panicles or nearly corymbs, few flowered. Flowers: pedicels very slender, elongate; sepals white, obovate-spatulate, 2.5-4 mm; filaments white, 2.5-4 mm; anthers 0.3-0.5 mm. Achenes 3-8, spreading; stipe 1-3(-4) mm, usually ± 1/2 as long (sometimes nearly as long) as achene body; body flat, falcate, 3-5 mm, abaxially convex, adaxially concave, conspicuously 3-veined on each face; beak minute.


Phenology: Flowering spring–summer (May–Jul).
Habitat: Rich moist woods, cliffs, seepage slopes, and mountain streams in mountains and piedmont
Elevation: 500 m
