Pholistoma membranaceum is a species of flowering plant in the family Hydrophyllaceae.[1] It is known by the common name white fiesta flower.[citation needed]
It is native to western North America from central California to Baja California.[2] It can be found in many types of habitat from mountain ravines to beaches to desert scrub generally below 4,500 feet (1,400 m) elevation.[2]
Description
[edit]Pholistoma membranaceum is an annual herb with a waxy, fleshy, bristly stem up to 90 centimeters long and branching profusely, sometimes forming a tangle. The leaves are deeply lobed or cut and borne on winged petioles. The foliage is coated in hairs.[3]
The inflorescence consists of cymes of 2 to 10 flowers each under a centimeter wide. Each pedicel is 5–20 millimetres (0.2–0.8 in). Calyx lobes are oblong and 1–3 millimetres (0.04–0.12 in). The flower is white, usually with a purple spot or streak on each of its five lobes.[3]
