The flora of the Playa Grande of Cartagena in the Valparaiso Region, commune of El Tabo (33°30´S, 71°36´W), is made up of 98 species of vascular plants, 61 % of which are exotics, most feral. The vegetation is made up of five units: a Carpobrotus chilensis and Chrysanthemum coronarium grassland dominated by ruderal species, mostly feral alien species, which marks the boundary between the populated area and the dune field with the sandy beach; a Ambrosia chamissonis and Poa cumingii scrub that is typical of the primary and secondary dunes and occupies the largest vegetated area in the study area; a Nolana crassulifolia scrub, a coastal rocky rocks; and two units typical of coastal wetlands: a marsh grassland with Schoenoplectus pungens and Cotula coronopifolia, and a Typha dominguensis grassland in a water body.

Keywords : Dunes; flora of Chile, urban coastal wetlands.
