Subnival and high montane tropical xerophytic geocomplex. 1. Cryomorphic open vegetation: Nototriche auricoma-Oriastrum sphaeroidalis community. Strongly-cryoturbed stony soils. 2. Xeromorphic bunch-grassland: Senecio puchii-Stipa frigida community. Cryoturbed high-montane slopes. 3. Xeromorphic bunch-grassland: Junellia pappigera-Festuca orthophylla community. Subnival volcanic sandy-gravel lapilli piedmonts with deep regosols. 4. Phreatophytic xeromorphic shrubland & thicket: Frankenia triandra-Parastrephia phylicaeformis community. Saline plains with shallow seasonal water tables or temporarily ponded. 5. Saline hygrophitic bunch-grassland: Xenophyllum incisum-Festuca scirpifolia community. Damp seasonally ponded saline soils. 6. Hygrophitic saline meadows and grassland: Xenophyllum incisum-Deyeuxia curvula community. Seasonally ponded alluvial plain. 7. Cushion-like peatbog: Zameioscirpus atacamensis-Oxychloe andina community. Saline seasonally flooded peat bog. 8. High-montane aquatic vegetation: Lilaeopsis macloviana-Ranunculus uniflorus-Potamogeton filiformis communities. Graphic interpretation based on our field transect data and cited references.
