Description

This species is an erect or spreading annual herb with a basal rosette of glaucous-green leaves. Leaves are highly ternately dissected, with ultimate lobes more rounded than pointed. Basal leaves measure 3-11 cm in length and 0.8-3.2 cm in width, with petioles comprising two-thirds of the leaf length. The inflorescence bears few flowers, up to 4 dm tall, with yellow petals 10.5-23 mm long. Flowers have 20-36 stamens with a darkened area at the fused filament bases. Buds are nodding, 4.5-11.5 mm long, with an apiculate tip less than 25% of the total length. The receptacle is obconic, 2.5-5.5 mm long, and the fruit is 3.5-6.5 cm long with 10-12 nerves. Seeds have reticulate ridges.
