Foggy tropical hyperdesert geocomplex. 1. Foggy coastal hyperdesert: Ephedra breana-Eulychnia iquiquensis community. Xeromorphic shrubland and thicket with cacti and succulents. Relictic on abrupt coastal cliffs and screes with Eulychnia population partially death. Windswept sands covering rocky substrates. Moderate to strong incidence of seasonal coastal fogs. 2. Foggy tillandsia hyperdesert: Tillandsia landbeckii community. Sandy mesodunes with persistent seasonal fogs. 3. Not vegetated hyperdesert. Bare desertic rocky pavement in sandy matrix. 4. Not vegetated hyperdesert. Salt flats without vascular vegetation (“Salar Grande”). 5. Deciduous thorn shrubland: Phreatophyllous disperse Prosopis tamarugo shrubs on salar microdunes. 6. Deciduous thorn woodland and shrubland: Caesalpinia aphylla-Prosopis tamarugo community. Open phreatophyllous saline vegetation in anastomosed silt channels with seasonal ephemeral drainage. Pampa del Tamarugal, Salar de Pintados. Graphic geobotanical interpretation based on our field transect data (1995) and cited references.
