Systematics, Biogeography, and Evolution of Malesian-Pacific Piper (Piperaceae).

Comprised of ~2000 spp., Piper is the most speciose genus in Piperaceae. Three major clades are recognized in Piper, i.e. the Neotropical, Asian and South Pacific clades. Unlike Neotropical Piper, relationships in the Paleotropic Piper remain enigmatic in that many of the previously recognized groups are not monophyletic. By combining data from GenBank (NCBI) and my data from Indonesia, I find that the major division within the Asian clade correlates with geography, suggesting Wallace’s Line in Malesia as the major boundary between lineages. I will discuss the implication of this preliminary result in the relationships within the Paleotropical clade, with emphasize in the Malesian-Pacific taxa, and examine their character evolution. The historical biogeography of the genus in Malesia, one of the most geologically complex areas in the world, will also be explored.
