Dypsis is a morphologically diverse genus restricted to Madagascar and adjacent islands. The genus has recently been revised and substantially expanded by J. Dransfield and H. J. Beentje (1995b). The most familiar species, D. lutescens (H. Wendland) Beentje & J. Dransfield, is hardly representative of the astonishing diversity in growth form , leaf shape, floral details, and fruit morphology found in the genus.[1]
