Plants perennial, scapose, from short rootstocks bearing yellow, globose bulblets. Leaves (10-)14-24(-30) × (4-)6-14(-18) cm; petiole (5-)8-16(-22) cm; blade with 4 orders of leaflets and lobes; abaxial surface glaucous; ultimate lobes linear to linear-elliptic or linear-obovate, (2-)5-15(-23) × (0.4-)2-4 mm, usually minutely apiculate. Inflorescences racemose, 3-12-flowered, usually exceeding leaves, (10-)15-27(-33) cm; bracts ovate, 2-5 × 1-3 mm. Flowers pendent, very fragrant; pedicels (2-)3-7(-14) mm; sepals triangular to ovate, 2-4 × 1-2 mm, apex acuminate; petals white; outer petals (10-)12-16(-20) × (2-)4-5(-8) mm, reflexed portion 3-5 mm; inner petals (10-)12-15(-18) mm, blade 2-4 mm, claw linear-elliptic, 5-9 mm, crest prominent, ca. 2 mm diam., exceeding apex by ca. 2 mm; filaments of each bundle distinct nearly to base; nectariferous tissue forming 0.5-1 mm spur oriented vertically; style 4-7 mm; stigma shallowly 2-horned with 2 lateral papillae. Capsules ovoid, attenuate at both ends, (5-)9-13(-17) × 3-6 mm. Seeds slightly reniform, very obscurely reticulate, elaiosome present.


Phenology: Flowering early–late spring.
