is an Australian species, naturalized in a few locations along the coast of southern California. Leaves are distinctive; flat, glaucous, angled about 90 degrees from the stem, and crossed by prominent parallel veins, between five and ten. Branches are woody, oily, unarmed, ridged, and have a faint vanilla scent.
The yellow flowers may be solitary or in elongated clusters (about as long as the leaves) of up to six, from the leaf nodes; they have five sepals, five inconspicuous petals and many stamens, these the most noticeable component. Fruits are brown, sickle-shaped pods, 1 to 2 inches long.
