    • n alfilerilla A name in California for a European species of Erodium, E. cicutarium, which has become very widely naturalized. It is a low herb, but a valuable forage-plant. Its carpels have a sharp point and a long twisted beak, by the action of which, under the influence of the moisture of the air, the seed is buried in the soil. Other names for it are pin-clover and pin-grass.
