Table 1 Richness (N) and percentage representation (%) of the vascular flora of Punta Arenas city; the number of species recorded for Santiago, La Serena, Valparaíso, Rancagua, and Talca cities is also indicated. Numbers in square brackets represent subtotals for the corresponding taxonomic category. Below are the statistical results (Chi–squared tests) after comparing the richness distribution between Punta Arenas and the rest of the cities for the Division and Family taxa; for these comparisons, the flora of Santiago was considered (Figueroa et al. [13]), and only the woody arboreal component of the other cities was included (Santilli et al. [9])
