“…Traditionally Vochysiaceae have been included in Polygalales, and its placement in Myrtales has only recently been proposed on the basis of molecular data (Chase & ai., 1993;Conti & ai., 1996Conti & ai., , 1997Sytsma & Baum, 1996). The presence of vestured pits, however, as well as bicollateral vascular bundles and several embryological features, corroborate the position of Vochysiaceae in Myrtales (Bailey, 1933;Quirk, 1980;Boesewinkel & Venturelli, 1987;Baas & ai., 2000).

Summary Jansen, S., Baas, P. & Smets, E.: Vestured pits: their occurrence and systematic importance in eudicots. – Taxon 50: 135–167. 2001. – ISSN 0040–0262. The distribution of vestured pits in secondary xylem reveals interesting patterns that may bear on hypotheses of phylogenetic relationships within eudicots. Vestured pits are found to be relatively widespread at the base of the eurosids I, eurosids II, and euasterids I, but the feature probably has been lost or originated independently in several more derived branches of these clades. Vestured pits characterise orders Myrtales and Gentianales sensu APG; other large monophyletic taxa that consistently show vestured pits include Malpighiaceae, Polygonaceae, Brassicaceae, and most Fabaceae. Representatives from euasterids II always show nonvestured pits. The occurrence of the character implies numerous parallel origins in the following divergent, major taxa: (1) Proteaceae, (2) Polygonaceae (Caryophyllales), (3) eurosids I (Zygophyllaceae, Fabales, very few Rosales, Malpighiales), (4) eurosids II (Myrtales, Malvales, Brassicales), and (5) euasterids I (Gentianales, Lamiales, Solanales). It is demonstrated that vestured pits frequently support results from DNA data.

“…Johnson and Briggs (1984) scored oil ducts as three different characters, distinguishing between stem ducts and petiole ducts; this needs further investigation, but the study by Carr and Carr demonstrated that they were not independent of each other, at least in eucalypts. Various members of Vochysiaceae, including Qualea, are reported to have ''traumatic axial gum ducts'' in their stems (Quirk, 1980). Although Ingle and Dadswell (1953, p. 397) noted that these are similar to those that occur in some members of the eucalypt group, we do not consider these gum ducts to be homologous with the oil ducts in Myrtaceae, and they are not scored as such.…”

“…Morphological data for this family are derived from Flores (1993a, b), Kawasaki (1998), A. Litt (Yale University, personal communication), and P. G. Wilson (personal observations). Following Johnson and Briggs (1984), we have taken data from Ingle and Dadswell (1953) and augmented it with data for Psiloxylon (Schmid, 1980), Heteropyxis (Stern and Brizicky, 1958;Schmid, 1980), Kunzea (Patel, 1994), Calyptranthes (Dias-Leme, Gasson, and Nic Lughada, 1995), Anetholea , and the Vochysiaceae (Quirk, 1980). The terminology of Ingle and Dadswell (1953) is adopted for wood anatomy.…”

Cladistic analyses are presented of matK sequence data as well as a nonmolecular database for an identical set of exemplar species chosen to represent the core genera or groups of genera in Myrtaceae. Eleven robust clades are recognized on the molecular data. Polyphyly of the previously recognized Metrosideros and Leptospermum alliances is confirmed, and several smaller informal taxonomic groupings are recognized from among the members of the former alliance, i.e., the Tristania, Tristaniopsis, Metrosideros, and Lophostemon groups. The nonmolecular analysis provides only limited resolution of relationships. A degree of congruence exists between the two analyses in that two separate fleshy-fruited clades, the Acmena and Myrtoid groups, are identified, as are the Eucalypt and Tristania groups, and Psiloxylon and Heteropyxis are the first lineages to diverge in both analyses. A combined analysis recognized all 11 clades that received strong support from the molecular data. A high level of homoplasy is revealed in many of the nonmolecular characters when they are examined against the combined estimate of phylogeny.
