Madia sativa is an annual herb varying in size from 20 centimeters tall to well over two meters, the leafy stem branching or not. It is coated densely in sticky resin glands and it has a strong scent. The hairy leaves are linear or lance-shaped, the lowest up to 18 centimeters long. The
inflorescence is generally a cluster of
flower heads lined with bristly, glandular
phyllaries. Each head bears approximately 8 yellowish ray florets a few millimeters long around a center of several disc florets tipped with dark
anthers. The fruit is a flat, hairless
achene with no
pappus. This plant has been grown for its seed oil. ==References==
