Paleotropis covers large part of Africa (except of its northern and southernmost continent edges), India, South Asia and Indonesia – Paleotropis includes all tropical areas of the Old World. This area is botanically very rich; we can find here 40 endemic families. Approximately 50 % of all tropical species is situated just in this floristic region.
