Eulychnia ritteri

A columnar Eulychnia from the fog-fed coastal desert of southern Peru, the only member of the genus outside Chile as usually treated. We have no wild records or measured climate, so these conditions come from the genus and its coastal fog habitat: very bright, mild, almost rainless, with humid sea air.

Where it grows wild

Believed to grow on coastal hills and slopes in the fog zone (lomas) of southern Peru, inferred from the genus and published locality notes; not confirmed by our data.

Unknown in our data; coastal fog-zone Eulychnia usually grow from near sea level to a few hundred metres.
