Bomarea with 100–110 species represents the most diverse genus of Alstroemeriaceae. The genus is distributed from Chile to Mexico and comprises twining, prostrate or erect herbs with tuberous storage roots and pendant, showy flowers. Phylogenetic relationships and patterns of evolution within Bomarea have not yet been explored. Thus, neither the currently accepted classification nor patterns of morphological evolution have been evaluated. To resolve relationships within Bomarea, we sequenced three cpDNA regions (psbA-trnH, rpoB-trnC, matK) and the nrDNA ITS spacer regions (ITS 1 and ITS 2). MP and ML analyses of the combined data recover three major lineages in the genus and the composition of these clades is inconsistent with previous classifications based on morphology and biogeography. Patterns of evolution for three morphological characters were investigated by mapping them onto the phylogeny. The analyses indicate that the ancestor of Bomarea had compound umbels, a twining habit, and foliar indument. The phylogenetic analyses were unable to obtain high support, which suggests a relatively recent and rapid radiation of this genus.
