Botanical Description
Clypeola jonthlaspi is a small annual herb in the family Brassicaceae, native to dry, open, often calcareous ground across the Mediterranean basin, North Africa, the Middle East and parts of central Asia, where it flowers briefly in early spring. It produces one or a few slender, erect, sparsely branched stems 5-25 cm tall, sparsely covered with stellate hairs, and small, entire, oblong-spathulate basal leaves crowded into a rosette, the cauline leaves few and reduced. Tiny pale-yellow four-petalled flowers about 2 mm across are borne in slender terminal racemes that elongate in fruit. The diagnostic fruits are flat, orbicular, one-seeded silicles 3-4 mm across, surrounded by a thin, papery, sometimes notched wing - resembling small disks, which gives the plant both its scientific and common names. The whole plant withers soon after seed-set.
