The name Airampoa derives from the native name of the plant (in Quechua, ayrampo, airampo, ayram pu means garnet red), whose fruits are used as a colouring in food, and as a dye.
Derived from the Quechua name ''ayrampo'', referring to the red fruits used as dye and food colouring.

Flowers are diurnal, self-sterile, bell-shaped, and of variable colour: yellow, orange, red, carmine red to purplish red, rarely white. The stigma pistil is emerald green. Pollination is provided by wasps and bees.

Etymology

Derived from the Quechua name ayrampo, referring to the red fruits used as dye and food colouring.

Description

Airampoa is a genus of small, compact opuntioid cacti forming low cushions.

  • Habit: Low-growing; strongly articulated; forming dense cushions.
  • Stems: Composed of small segments; compact and clustered.
  • Leaves: Small, cylindrical, deciduous.
  • Areoles: Bearing glochids.
  • Spines: Fine, acicular; variable in size and colour.
  • Flowers: Diurnal; self-sterile.
  • Flower shape: Bell-shaped.
  • Flower color: Yellow, orange, red, carmine to purplish; rarely white.
  • Stigma: Emerald green.
  • Pollination: By bees and wasps.
  • Fruits: Fleshy; yellow to red; laterally dehiscent; with red pulp.
  • Seeds: Small; flattened; kidney-shaped; wrinkled; often stained by fruit pigments.
  • Seed dispersal: By birds (notably rheas).

Habitat

Occurs in high-altitude Andean environments:

  • puna and altiplano regions
  • gravelly or sandy soils
  • open ground or under sparse shrubs

Altitude range: approximately 1800–4000 m.

Distribution

South America:

  • Argentina
  • Bolivia
  • Northern Chile
  • Southern Peru

Taxonomy

A problematic and variable genus.

Key points:

  • Previously included in Tunilla (Hunt & Iliff, 2000)
  • Re-established as Airampoa (Guiggi, 2007) following nomenclatural revision
  • Distinguished by pollen morphology (perforated tectum vs reticulate in Opuntia)
  • Molecular studies place it within Opuntieae but outside Opuntia sensu stricto
  • High morphological variability possibly due to hybridization

The genus is accepted as distinct in Lodé (2015), though species delimitation remains uncertain.

Species

According to Joël Lodé (2015):

Notes

  • Previously confused with Tunilla.
  • Likely contains fewer true species than currently listed.
  • Exhibits extreme morphological variability across populations.
  • Fruits traditionally used as natural dyes.
  • Represents a distinct Andean lineage within Opuntieae.
