Cumulopuntia

(Colla) F.Ritter

(Cárdenas) E.F.Anderson

A cushion-forming cumulopuntia from southern Peru. Today's treatment also includes plants described in the Arequipa revision as Cumulopuntia mistiensis, so population characters must be read alongside the name used by the author.

(Vaupel) E.F.Anderson

A cumulopuntia with variable stem-segment shape, from ovoid to spindle-shaped. Field revision demonstrated this variation in natural habitats as well.

(F.Ritter) F.Ritter

A species described in 2021 from northwestern Bolivia, forming hemispherical clusters with dense, flexible white spines.

A high-Andean cumulopuntia with red or red-orange flowers, a thick root and compact cushion growth. In a controlled experiment, its seeds required light to germinate.

G.J.Charles

A cumulopuntia associated partly with dry sections of Peruvian lomas. The regional revision characterizes it by fibrous roots, loose growth and usually straight spines.

A narrow endemic of the Río Yauca valley with soft, flexible spines and tightly packed stem segments. The 2023 description documents a plant from a very small area at 1700–1800 m elevation.

(Salm-Dyck) F.Ritter

(Heinrich & Backeb.) F.Ritter

A variable species in which POWO now includes several cumulopuntias formerly described separately. Detailed data from Arequipa present both its narrow treatment and variation among populations historically distinguished.

(R.E.Fr.) F.Ritter

A low cumulopuntia from the Uchumayo area in Arequipa, distinguished by often wavy spines. Its current nomenclatural combination was correctly established in the 2020 revision.

A cushion-forming species from southern Peru with fibrous roots and abundantly hairy areoles. It combines a compact habit with characters of the cumulopuntia group with dry fruits and relatively large flowers.
