Abstract

Loranthaceae, with 73 genera and ca. 900 species, comprises mostly aerial hemiparasitic plants. Three monotypic genera considered to be relicts in the family are root parasites. The family is diverse in tropical areas worldwide, but representatives are also found in temperate habitats in the Old and New World. Previous classifications were based on floral and inflorescence morphology, karyological information and biogeography. The family has been divided into three tribes: Nuytsiae, Elytrantheae (subtribes Elytranthinae and Gaiadendrinae), and Lorantheae (subtribes Loranthinae and Psittacanthinae). Tribes Nuytsiae and Elytrantheae are characterized by a base chromosome number of X=12 whereas subtribe Loranthinae (X=9) and subtribe Psittacanthinae (X=8) numbers are derived via aneuploid reduction. To elucidate the phylogeny of the family, sequences from five genes (nuclear small and large subunit rDNA and the chloroplast genes rbcL, matK, and trnL-F) representing most genera were analyzed, each gene individually and as a concatenated data set, with maximum parsimony, likelihood and Bayesian inference. The three root parasites, Nuytsia, Atkinsonia and Gaiadendron, are supported as successive sister taxa to the remaining genera, resulting in a monophyletic group of aerial parasites. Three major clades are resolved each corresponding to a subtribe. However, two South American genera (Tristerix and Notanthera) and the New Zealand genus Tupeia, which were previously classified in subtribe Elytranthinae, are weakly supported as part of a clade representing the South American subtribe Psittacanthinae.
