	abstract = {Evidence from wood, leaf, and floral anatomy, from palynology, and from reconsideration of vegetative and reproductive morphology fully support (1) the placement of Heteropyxis by Fernandes (1971), Stern \& Brizicky (1958), and Weberling (1963) in Myrtaceae/Leptospermoideae on the basis of organography, palynology, and petiole and wood anatomy, and (2) the placement of Psiloxylon by van Tieghem (1904) in Myrtaceae on the basis of especially vegetative anatomy. Diagnostic myrtaceous characters shared by both genera include: entire, simple, gland-dotted, penninerved leaves wth intramarginal veins; rudimentary stipules (Heteropyxis only); pentamery; nectary lining floral tube; imbricate, persistent calyx; many pollen features; sunken styles; baccate or capsular fruits (resp. Psiloxylon and Heteropyxis); exalbuminous seeds; bicollateral bundles; secretory cavities in all aerial organs, including the anthers; unilacunar one-trace nodes; arcuate petiolar bundles with sclerenchymatous sheaths (only in lamina of Psiloxylon); vestured pits; wood fibers with distinctly bordered pits; and tannin. Both genera, however, differ from many, but not all Myrtaceae in having: alternate leaves; unisexual, but bisexual-appearing flowers (only the staminate in Psiloxylon); perigyny; few stamens (Psiloxylon diplostemonous, Heteropyxis essentially obdiplostemonous); short style and divided stigma (Psiloxylon only); cancellate seed (Psiloxylon only); and such wood characters as septate, crystalliferous fibers and lack of vasicentric tracheids in Psiloxylon, and lack of axial parenchyma in Heteropyxis. The segregates Heteropyxidaceae and Psiloxylaceae should thus be included in Myrtaceae. The foregoing ensemble of characters conclusively excludes for Heteropyxis any assignment to Rhamnaceae or Rutaceae, for Psiloxylon any assignment to Bixaceae sensu lato, Flacourtiaceae, or Guttiferae, and for both genera an assignment to Lythraceae. Because it would be anomalous in either of the two traditional myrtaceous subfamilies, Psiloxylon is best treated as a new subfamily in Myrtaceae. Finally, since Leptospermeae and Chamaelaucieae differ as much from each other as either does from Myrteae, Chamaelaucieae should be elevated to subfamilial status in Myrtaceae. The family Myrtaceae thus has four subfamilies: Myrtoideae, Psiloxyloideae, Leptospermoideae, and Chamaelaucioideae. An addendum discusses Briggs \& Johnson{\textquoteright}s (1979) detailed paper on vegetative and especially reproductive structure of Myrtaceae.},

	abstract = {With as many as 1000 included species, Syzygium s.l. (including Syzygium and segregate genera such as Acmena, Acmenosperma, Cleistocalyx, Piliocalyx, and Waterhousea) comprises one of the major lineages within Myrtaceae, and is an important component of the Old-World tropical rainforest flora. As with other large genera, high species richness, an extensive distribution and relative homogeneity in morphology have hindered attempts to divide Syzygium s.l. Here, we investigate higher level relationships within the group, using parsimony and Bayesian analyses of cpDNA sequences from the matK and ndhF genes and the rpl16 intron, generated for a total of 87 species from the Syzygium group and eight outgroup taxa. Within the ingroup, four major well supported clades are found, which form a basal polytomy along with S. wesa and monotypic Anetholea. Generally, the molecular data provide little support for traditional divisions of Syzygium s.l., and the recognition of segregate groups such as Acmena, Acmenosperma, Cleistocalyx, Piliocalyx and Waterhousea. While homoplasy amongst morphological characters has misled attempts to divide the group, detailed and critical assessments of placental, ovular and seed morphology may provide novel insights into evolutionary relationships, and are an important future step in the development of a sound higher level taxonomy for Syzygium s.l.},
