Popis: The evolutionary distinctiveness and phylogeneticposition of Marantaceae within Zingiberales is stronglysupported by morphological and molecular data analyses(Kress, 1990, 1995; Kress & al., 2001). Cannaceae, amonogeneric family with about 10 species (Kubitzki,1998; but see Tanaka, 2001), are the closest relative ofMarantaceae. These two families are sister to the familypair Zingiberaceae and Costaceae. Marantaceae includes31 genera and ~535 species distributed throughout warmtemperate and tropical parts of the world (Andersson,1998) with 14 genera in the New World, 11 genera inAfrica (including Madagascar), and eight genera in Asia.Only the genera Thalia and Halopegia occur on morethan one continent. The current geographic distributionof the family is likely due to secondary intercontinentaldispersal events (Kress & Specht, in press; Prince K Watt, 1892; van denBerg, 1984; W. J. Kress, pers. obs.).Andersson (1998) described Marantaceae as prima-rily “jungle weeds”, taking advantage of light gaps tocomplete their life cycle. He noted two genera, Thaliaand Halopegia , that are “confined to open marshes”although the latter often occurs in shady habitats as wellin tropical Asia. The growth habits of some African andAsian Marantaceae are somewhat different from thosefound in the Americas. “Marantaceae forests”, which arelarge expanses of herbaceous vegetation dominated by
