Similar to the blue mustard (Chorispora tenella), but has greener sepals, no glandular hairs on pedicels and fruits and terete siliques without a beak. The seeds shown below are also quite distinct.

Description: African mustard (Strigosella africana syn. Malcolmia africana), Mustard family (Brassicaceae). Grown from seeds collected from Badeau Ridge near the Yuba State Park, Utah. It is an annual plant, but I expect it to re-seed. Hope, it will not be too difficult to control. Date: 10 April 2016, 12:03. Source: 2016.04.10_12.03.07_DSC03238.
