姜目中马兰科的进化独特性和系统发育位置得到了形态学和分子数据分析的有力支持（Kress，1990，1995；Kress & al.，2001）。 Cannaceae 是一个单属科，约有 10 种（Kubitzki，1998；但参见 Tanaka，2001），是 Marantaceae 的近亲。这两个科是姜科和胭脂科的姊妹科。 Marantaceae 包括 31 属、约 535 种，分布在世界暖温带和热带地区（Andersson，1998），其中新大陆有 14 属，非洲（包括马达加斯加）有 11 属，亚洲有 8 属。只有 Thalia 属和 Halopegia 属分布在多个大陆上。该科目前的地理分布可能是由于次生洲际扩散事件所致（Kress & Specht，出版中；Prince K Watt，1892；van denBerg，1984；W. J. Kress，pers. obs.）。Andersson（1998）将马兰科科描述为原始丛林杂草，利用光照间隙来完成其生命周期。他指出，Thalia 和 Halopegia 两个属仅限于开阔的沼泽地，尽管后者经常出现在阴凉的栖息地以及热带亚洲。一些非洲和亚洲马兰科植物的生长习性与美洲发现的有些不同。马兰科森林，是大片草本植被，以
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 marshesalthough 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
