La Melba. Alejandro de Humboldt National Park

Lowland rainforest on metamorphic complex (pluvisilva de baja altitud sobre complejo metamуrfico). This is Cuba’s most exuberant rainforest type. Generally, there are two arboreal layers. The upper layer frequently reaches 30 to 35 m; when it only reaches 20 to 25 m (sometimes less), it hasemergents reaching 35 m. In some, more well-developed places there are three layers: The first is between 35 and 45 m (Carapa guianensis), the second reaches approximately 25 m, and the third is between 8 to 18 m. Arboreal canopy coverage is 100%. Upper layers mostlyare made up of Carapa guianensis, Guarea guidonia (Meliaceae), Ocotea floribunda (Lauraceae), and Oxandra laurifolia (Annonaceae). To a lesser degree, Zanthoxylum martinicense (Rutaceae), Schefflera morototoni (Araliaceae), Cupania american (Sapindaceae), Sapium jamaicense (S. laurifolium, Euphorbiaceae), and Cecropia schreberiana (Cecropiaceae) are also present. Other species, such as Prestoea acuminata var. montana (Arecaceae), Dendropanax arboreus (Araliaceae), and Ocotea leucoxylon (Lauraceae) can be found. The lower arboreal layer is composed most often of Carapa guianensis, Prestoea acuminata var. montana, Oxandra laurifolia, and Calyptronoma plumeriana (Arecaceae); other less frequent species include Hirtella triandra (Rosaceae), Cupania americana, and Miconia elata (Melastomataceae). And occasional species include Dendropanax arboreus, Guarea guidonia, Cecropia schreberiana, Gerascanthus sulcatus (Boraginaceae), and Cyathea aspera (Cyatheaceae).
