High-montane humid bunch-grassland geocomplex. 1. High-montane bunch-grassland: Deyeuxia vicunarum-Festuca orthophylla communities. Zonal humid Puna vegetation on high-montane stony well-drained hillside soils. 2. Meadow’s grassland: Deyeuxia rigescens-Festuca humilior communities. Seasonally ponded or saturated wet Puna flat soils. 3. Flat-cushion peatbog: Deyeuxia rigescens-Plantago tubulosa communities. Seasonally flooded peaty vegetation. 4. Domed-cushion wet peatbog: Oxychloe andina-Distichia muscoides communities. Permanently flooded peaty vegetation. 5. Puna aquatic vegetation: Isoetes lechleriana community.
