Allium lacunosum is a species of wild onion known by the common name pitted onion. It is endemic to California, where it is a common member of the flora in many types of habitat, from bayside to mountain to desert. This onion grows from a thick-coated yellowish-brown bulb one or two centimeters long. The stem reaches up to about 35 centimeters in maximum height and there are usually two leaves which may be as long or longer than the stem. The flower cluster contains up to 45 dark-veined white to pale pink flowers, each less than a centimeter long. There are four varieties of this species, three of which are somewhat uncommon.
