Middled.

A small species from near Huasco in Chile, formerly described as Copiapoa humilis subsp. australis. Chloroplast data supported its separation and showed its close position to the much larger Copiapoa solaris.

A coastal Chilean species with branching stems. Molecular studies place it in a group containing Copiapoa montana and C. marginata. The site's archive contains detailed observations of its cultivation.

(Salm-Dyck) Britton & Rose

Pumarino & Blando

A small cactus with a taproot and a globose stem bearing distinct tubercles. Its current circumscription includes several subspecies, among them tenuissima, known from studies of regeneration in tissue culture.

A small geophytic species of coastal Chile, with a thickened root and low stem. Its similarity to Copiapoa laui has been examined as an example of the independent origin of similar growth forms.

A small cactus with a storage root and a low stem bearing few spines. The older names Copiapoa hypogaea var. laui and C. hypogaea subsp. laui refer to this currently accepted species.
