Comandra
umbellata
(Bastard Toadflax) Santalaceae (Sandalwood Family) Semi-desert, foothills. Meadows, openings. Spring, summer. Comandra umbellata is hemiparasitic, attaching itself to the roots of other plants and deriving at least some nourishment from them. It has green leaves and thus also photosynthesizes. It spreads by underground roots and can form large colonies in meadows and along roadsides, as pictured below. Or it can grow in small numbers, even inserting itself into rock crevices, as the picture at left shows. The star-shaped flowers are white to pink, tiny, and massed. Leaves are short and somewhat thick, resembling those of a succulent. The plant is not a relative of Toadflax but someone thought the leaves resembled those of Toadflax, hence the common name. Comandra umbellata is a relative of the Australian Sandalwoods, and our species is one of two worldwide in this genus. The plant was first named Thesium umbellata by Linnaeus in 1753, but in 1818 Thomas Nuttall moved it to a new genus he named Comandra. "Comandra" is from the Greek for "male hairs" and refers to hairs on the stamens. "Umbellata", "umbrella like", refers to the shape of the flower clusters -- though we now call this shape a "corymb". |
