Gaussia is a genus of five species of feather palms in the family Arecaceae (order Arecales), native to Mexico, Central America, and the Greater Antilles. The trees are solitary and unarmed, bearing large pinnately compound (feather) leaves. A distinctive feature of the genus is the markedly swollen or tapered base of the trunk, which is often accompanied by conspicuous prop-roots that anchor the tree in its forest habitat.
The five recognized species occupy distinct geographic ranges across the neotropical region: Gaussia maya occurs in southern Mexico, Belize, and Guatemala; Gaussia gomez-pompae is endemic to the Mexican states of Chiapas, Oaxaca, and Veracruz; Gaussia attenuata is found in Puerto Rico; Gaussia princeps is restricted to western Cuba; and Gaussia spirituana grows in the Sierra de Jatibonico of east-central Cuba. The genus thus spans the Caribbean island arc and the Mesoamerican mainland, reflecting a biogeographic pattern common among relict palm lineages in the region.
Distribution
Gaussia is native to Mexico (Chiapas, Oaxaca, Veracruz), Central America (Belize, Guatemala), and the Greater Antilles (Cuba, Puerto Rico). Individual species occupy narrow, often endemic ranges across this neotropical arc.
