“…Sakai et al (1995) hypothesized that Hawaiian Melicope and Platydesma both arose from separate colonizations; the Melicope colonist was dimorphic while the ancestor of Platydesma was monomorphic. The results of molecular phylogenetic analyses (Harbaugh et al 2009, Appelhans et al 2014a,b) demonstrate that Hawaiian Melicope and Platydesma most likely arose from a single ancestor. The ancestor of Hawaiian Melicope + Platydesma was likely dioecious, because the closest relatives of the Hawaiian species (=the remainder of Melicope section Pelea excluding species from New Caledonia) are almost exclusively dioecious (Hartley 2001).…”

“…Recent molecular phylogenetic studies provided unequivocal evidence for the placement of Platydesma within Melicope , as sister to the Hawaiian taxa in Melicope section Pelea (Harbaugh et al 2009, Appelhans et al 2014a, 2014b; Fig. 1).…”

“…Engler (1931) placed Platydesma between the North American (Mexico and southwestern USA) genus Choisya Kunth and the New Caledonian genus Dutaillyea Baill., while Stone (1962a) hypothesized that the genus was derived from the Australian, New Caledonian and New Guinean genus Medicosma Hook. f. Even though Dutaillyea proved to be part of Melicope , and Medicosma is the sister genus of Melicope , neither of these taxa are immediate relatives of Platydesma and the Hawaiian Melicope species (Appelhans et al 2014a). While most Melicope species have a dimorphic breeding system (Sakai et al 1995, Hartley 2001), Platydesma is a peculiar taxon for its monadelphous stamens and bisexual flowers (Hillebrand 1888, Kubitzki et al 2011).…”

“…He also mentioned characters of the New Caledonian species that do not occur in other species of the section or the genus, among which are: abruptly acuminate flower buds, and persistent and accrescent sepals and/or petals (Hartley 2001; p. 140). Molecular phylogenetic studies (Appelhans et al 2014a,b; Fig. 1) have shown that the New Caledonian species of section Pelea are not directly related to the Hawaiian species and the remainder of section Pelea, but that they belong to a clade of taxa from New Caledonia, Australia, New Zealand and the South Pacific, including Melicope sections Melicope p.p.…”

Wagner. An additional species that has been recognized within Platydesma should now be recognized under its original name M. spathulata A. Gray. All Hawaiian species belong to Melicope section Pelea. Our molecular phylogenetic studies also showed that in addition to merging Platydesma into section Pelea, five species described from New Caledonia need to be excluded from the section in order to achieve monophyly of section Pelea.

Pyrularia is a small parasitic genus of the Santalales with two to five species exhibiting a well-known classical intercontinental disjunct distribution between eastern Asia (EA) and eastern North America (ENA). Pyrularia and another santalaceous genus Buckleya represent the only two parasitic plant lineages with the EA-ENA disjunction. The present study was carried out to assess the species number and molecular and morphological differentiation in Pyrularia, and to reconstruct the biogeography of the Pyrularia clade (Pyrularia and its close allies) using dating and biogeographic inferences. A phylogenetic analysis based on two nuclear and seven plastid markers strongly supported the monophyly of Pyrularia and revealed two highly distinct subclades corresponding to EA and ENA within the genus. Incongruent topologies within the eastern Asian lineage were found between the nuclear and the plastid datasets, which may be attributed to incomplete lineage sorting. Morphometric and phylogenetic analyses suggest that Pyrularia in eastern Asia may best be treated as a single species, P. edulis. Molecular dating based on four markers suggested that the divergence time between the intercontinental species was in the late Miocene at 5.58 Ma (95% HPD: 2.08-11.72 Ma), which was close to the split of the trans-Pacific clades within the other parasitic EA-ENA disjunct genus Buckleya. The EA-ENA disjunction in the only two parasitic genera may have resulted from the fragmentation of the mesophytic temperate forests in the late Miocene. The Pyrularia clade (including the close allies of Pyrularia) was inferred to have originated in Africa, then dispersed to Asia, and subsequently to North America via the Bering land bridge, resulting in the current intercontinental EA-ENA distribution of Pyrularia.Supporting Information may be found online in the Supporting Information section at the end of the article.

The monophyly of Boronia (Rutaceae) was tested using 134 accessions of 120 species belonging to 39 genera from subfamily Amyridoideae. Taxa included representatives of all eight sections of Boronia plus species of most genera in the two main clades related to Boronia that had been identified by earlier studies. These samples included a good representation of genera from both rainforest and sclerophyllous biomes. Maximum parsimony and Bayesian inference analyses were performed using three plastid markers (psbA‐trnH, trnL‐trnF, rbcL) and two nuclear ribosomal markers (ITS, ETS). Separate analyses of plastid and nuclear sequences using either maximum parsimony or Bayesian inference analyses recovered similar topologies. Apart from Boronia, the broad generic relationships of previous analyses were largely supported. Boronia is polyphyletic with section Cyanothamnus being more closely related to a large clade containing genera found in rainforest, including Melicope, Acronychia and their relatives. The remaining seven sections of Boronia formed a strongly supported and isolated group. Boronia sensu stricto is sister to a clade containing the Cyanothamnus‐Melicope‐Acronychia clade plus a clade containing Euodia, Zieria and other small genera found in rainforest or sclerophyllous communities. Issues with circumscriptions of ingroups and outgroups for previous analyses of Boronia and the complex relationship between Australasian genera found in rainforest and sclerophyllous communities are both discussed. Cyanothamnus is reinstated at generic level. Appropriate nomenclatural changes are made to transfer all currently recognised series, species, subspecies and varieties of Boronia sect. Cyanothamnus to the genus Cyanothamnus.
