The genus Martellidendron, previously recognized as a section of the genus Pandanus, was separated in 2003 on the basis of phylogenetic studies that used chloroplast DNA sequence data.[1] Martellidendron comprises seven species.[1]MorphologyMartellidendron plants are dioecious, that is, the male and female flower are on separate plants. The male flowers have many stamens (as many as 100).[1] and grow in an inflorescence that consists of spikes surrounded by bracts.[1] As the female flowers mature, they merge into an oblong or spherical multiple fruit.[1] An individual fruit is a drupe with two chambers.[1]Species
