Lepidium dictyotum

Lepidium dictyotum is a species of flowering plant in the mustard family known by the common names alkali pepperweed and alkali pepperwort.

It is native to the far western United States. [1] It grows in dry saline and alkaline soils, such as dry lakebeds. [2]


Lepidium dictyotum is a hairy annual herb producing decumbent or spreading stems up to about 20 centimeters long. They are lined sparsely with small leaves divided into fingerlike lobes.

The inflorescence is a mostly erect raceme of tiny flowers. Each flower is made up of millimeter long sepals and occasionally a white petal, although the petals are usually absent.

The fruit is a dehiscent silique 3 or 4 millimeters long divided into two valves, each containing a seed.
