    To provide an inter-continental overview of the floristics and biogeography of drought-adapted tropical vegetation formations, we compileda dataset of inventory plots in South America (n=93), Africa (n=84), and Asia (n=92) from savannas (subject to fire), seasonally dry tropicalforests (not generally subject to fire), and moist forests (no fire). We analysed floristic similarity across vegetation formations within andbetween continents. Our dataset strongly suggests that different formations tend to be strongly clustered floristically by continent, and that among continents, superficially similar vegetation formations (e.g. savannas) are floristically highly dissimilar. Neotropical moist forest,savanna and seasonally dry tropical forest are floristically distinct, but elsewhere there is no clear floristic division of savanna and seasonallydry tropical forest, though moist and dry formations are separate. We suggest that because of their propensity to burn, many formations termed “dry forest” in Africa and Asia are best considered as savannas. The floristic differentiation of similar vegetation formations from differentcontinents suggests that cross-continental generalisations of the ecology, biology and conservation of savannas and seasonally dry tropicalforests may be difficult.
