Distribution and habitat

This species has a widespread distribution in coastal locations and inland along coastal valleys and on slopes of the Coastal Cordillera, from sea level to 1300 m. The southern limit occurs just south of Los Villos (Region Coquimbo) and its northern extremity is inland along the Rio Copiapó (Region Atacama). It grows in a wide range of habitats: coastal desert, scrub and sclerophyllous forest and is a component of the desert fog oasis. In the southern part of its range it often occurs with Leucostele chiloense and in common with this species it is parasitized by the conspicuously red flowered Tristerix aphyllus.
