'''''Iochroma cardenasianum''''' is a spiny shrub bearing very small leaves, a yellow trumpet-shaped campanulate flower, measuring some 3 cm long and [[globose]] fruit. The growth habit is somewhat reminiscent of certain ''[[Lycium]]'' species. It is endemic to [[Bolivia]], growing in dry, [[Andean]] valleys at altitudes of 2,000–2,500 m and 3,000–3,500 m and has been collected near the town of [[Cotagaita]] in [[Potosí Department]]. Recent research has revealed that, far from being a species of ''[[Iochroma]]'', it does not even belong in tribe [[Physaleae]] (to which ''Iochroma'' belongs), constituting instead an (as yet unnamed) [[monotypic genus]] in tribe [[Datureae]], and thus is most closely related to the genera ''[[Datura]]'' and ''[[Brugmansia]]'', species of which are well known as ornamentals and [[hallucinogens]], owing their activity to [[tropane alkaloid]] content.<ref>De Witt Smith,Stacey;David A.

Iochroma cardenasianum is a spiny shrub bearing very small leaves, a yellow trumpet-shaped campanulate flower, measuring some 3 cm long and globose fruit. The growth habit is somewhat reminiscent of certain Lycium species. It is endemic to Bolivia, growing in dry, Andean valleys at altitudes of 2,000–2,500 m and 3,000–3,500 m and has been collected near the town of Cotagaita in Potosí Department. Recent research has revealed that, far from being a species of Iochroma, it does not even belong in tribe Physaleae (to which Iochroma belongs), constituting instead an (as yet unnamed) monotypic genus in tribe Datureae, and thus is most closely related to the genera Datura and Brugmansia, species of which are well known as ornamentals and hallucinogens, owing their activity to tropane alkaloid content.[1] The specific name 'cardenasianum' commemorates eminent Bolivian scientist Martín Cárdenas (1899–1973).
