The present work provides an inventory of the plants observed in two distinct coastal grasslands ecosystems: the Azores Archipelago (in São Miguel Island) and Portugal mainland (Sesimbra and Sines regions – Setúbal district). Thirty-one plots were selected in coastal grasslands: thirteen were located on São Miguel Island and eighteen on the mainland, distributed across Sesimbra (12) and Sines (6). All plots were visited once during the spring of 2022. In each plot, 30 photos were taken at 5-meter intervals, for a total of 930 photos. A total of 213 plants species and morphospecies were observed in the two coastal grasslands (Azores = 98; Mainland = 132). In the Azores, 98 species and morphospecies belonging at three classes were observed: Liliopsida, Magnoliopsida, and Polypodiopsida. In mainland a total of 132 species and morphospecies were observed, belonging to four classes: Genopsida, Liliopsida, Magnoliopsida and, Pinopsida. In total, 17 species were common between the two regions.
