Part of R. Good's (1974, The Geography of the Flowering Plants) Neotropical floral kingdom, corresponding to one of the blocks of the rain forest. Because of extensive flooding by the Amazon river, the vegetation can be divided into that which is above the flood-level, called ‘terra firme’, and that which is below it, called ‘igapo’ or ‘varzea’. The flora of this vast region is one of the richest in the world. See also floral province; floristic region.
