Euphorbia magdalenae is a semi-succulent shrub in the genus Euphorbia, commonly known as Magdalena Island spurge or golondrinón.
It is a local endemic often found on hillsides, arroyo beds and bajadas within the Mexican state of Baja California Sur, particularly from VizcaÃÂno to the Cape Region. The species is characterized by its distinctive leaf arrangement and is usually found in desert or dry shrubland environments.
It was first described in 1844 by English botanist, George Bentham.
