Veiny Pepperweed is an introduced herbaceous annual in the Mustard family (Brassicaceae). It is native from Mississippi and Missouri westwards to California and south into Central America. In Alabama it has been found in central and northwestern portions of the state. Veiny Pepperweed grows along railroads and roads, in disturbed fields, and in other open, disturbed, often calcareous sites. It is an annual with a tap root. There are several erect or decumbent stems from each crown. Basal leaves are often withered at the time of flowering. The stems are green or purple in color and pubescent. Leaves are sessile or short petiolate, alternate, 1-2 times pinnatifid, with the lobes entire or toothed. The leaves are obovate to oblanceolate in outline and glabrous. Flowers are produced in elongated terminal racemes. Each flower is on a horizontal or divergent pedicel that is pubescent. The flowers lack petals and have two stamens. The fruit is a silicle.--A.
