Leaf: basal or basal and cauline, 1–4-pinnate- dissected, segments narrow.
Inflorescence: cyme, 1–many-flowered.
Flower: receptacle funnel-shaped, tip cupped around ovary base, outer receptacle rim occasionally spreading; sepals 2, fused, shed as unit at flower; petals generally 4 (except doubled flowers), free, obovate or wedge-shaped, generally yellow to orange (white or pink), shed after flower leaving crown-like membrane (inner receptacle rim); stamens 12–many, free; carpels 2, style 0, stigma lobes 4–8, spreading, linear.
