One to several scapes are curved-ascending from 15-50 cm long at maturity.
The rays of the compound umbels are unequally elongate, with the longer ones ranging from 3-7 cm long at maturity. The few bracts below the individual umbels are 1-3 mm long at flowering and up to 5 mm at maturity. The flowers are yellow. The slender pedicels range from 6-22 mm long at maturity. The fruits are glabrous and elliptic in shape, ranging from 5-6.5 mm long and up to half as wide. The narrow wings range from 1/3 to 1/2 the width of the body of the fruit.
