Distribution, systematics and endangerment
The distribution area of Cleistocactus baumannii extends from northeast Argentina via Paraguay and Bolivia to southern Brazil . The species is common at altitudes of up to 1000 meters.
It was first described as Cereus baumannii in 1844 by the French botanist Charles Lemaire . In 1861 he placed them in the genus Cleistocactus, which he had newly created . Another nomenclature synonym is Aporocactus baumannii (Lem.) Lem. (1860).
