%X a phytosociological interpretation of vegetation from sandy hills of the peruvian desert. the vegetation of the sandy hills (¡°lomas¡±) constitutes the main originality of the peruvian and chilean desert with a high number of endemics that shapes the vicarious associations. in this work, a phytosociological view of sandy environments of the peruvian coastal desert is presented. according to the braun-blanquet method, we have made up 32 phytosociological inventories and added 138 ones from others authors. in each inventory, we have analyzed its floristic composition and ecological parameters, as altitude, soil and geomorphology. all releves were synthesized in a table to deduce the different associations, higher phytosociological units, and the distribution of its flora along the peruvian coast and the andean cordillera. using the shannon-wiener diversity index, the diversity of this flora is discussed making a comparison with historical data about the use of the territory with livestock during pre-inca and inca cultures, and spanish invasion. as a result, two associations from southern peru -nolanetum scaposo-spathulatae and palauetum camanensis-weberbaueri-, two alliances -nolanion humifusae from central peru, and nolanion spathulatae from the southern peru- and a new order -tetragonio crystallinae- plantaginetalia limensis- are described. in nolanetum scaposo-spathulatae, dictyophragnus englerianus, leptoglossis lomana, nolana scaposa, n. spathulata, palaua velutina and tetragonia vestita are the main characteristics, while in palauetum camanensis-weberbaueri association n. scaposa and p. velutina are replaced by palaua camanensis and p. weberbaueri. nolanion humifusae alliance integrates species as geranium limae, hymenocallis amancaes, nolana humifusa, n. latipes, palaua rhombifolia or villanova oppositifolia. likewise, cistanthe weberbaueri, cryptantha parviflora, hoffmannseggia miranda, lupinus mollendoensis, nolana confinis, n. pallidula, n. scaposa, n. spathul
