“…Before the advent of modern phylogenetics, Warburg (1897: 102) proposed a 'hypothetical genealogical tree of the genera of Myristicaceae' in his main monograph of the family.

Two pre-cladistic views on the origin of the family are, however, worth mentioning.…”

Magnoliales, consisting of six families of tropical to warm‐temperate woody angiosperms, were long considered the most archaic order of flowering plants, but molecular analyses nest them among other eumagnoliids. Based on separate and combined analyses of a morphological matrix (115 characters) and multiple molecular data sets (seven variable chloroplast loci and five more conserved genes; 14 536 aligned nucleotides), phylogenetic relationships were investigated simultaneously within Magnoliales and Myristicaceae, using Laurales, Winterales, and Piperales as outgroups. Despite apparent conflicts among data sets, parsimony and maximum likelihood analyses of combined data converged towards a fully resolved and well‐supported topology, consistent with higher‐level molecular analyses except for the position of Magnoliaceae: Myristicaceae + (Magnoliaceae + ((Degeneria+Galbulimima) + (Eupomatia+ Annonaceae))). Based on these results, we discuss morphological evolution in Magnoliales and show that several supposedly plesiomorphic traits are synapomorphies of Magnoliineae, the sister group of Myristicaceae (e.g. laminar stamens). Relationships within Annonaceae are also resolved with strong support (Anaxagorea basal, then ambavioids). In contrast, resolution of relationships within Myristicaceae is difficult and still incomplete, due to a very low level of molecular divergence within the family and a long stem lineage. However, our data provide good evidence that Mauloutchia is nested among other Afro‐Malagasy genera, contradicting the view that its androecium and pollen are plesiomorphic © 2003 The Linnean Society of London, Botanical Journal of the Linnean Society, 2003, 142, 125–186.

Vantanea maculicarpa (Humiriaceae): a new tree species from French Guiana

A new species of Humiriaceae, Vantanea maculicarpa, growing in French Guiana terra-firme forest is described and illustrated. This new species is distinguished from all other species of Vantanea by fruits covered by white lenticels, a character so far unknown in this genus. It also presents a pubescent intrastaminal disk, a feature encountered in two other Vantanea species only: it is further distinguished from V. parviflora, the morphologically most similar species, by more stamens and from V. ovicarpa by a much smaller rough endocarp with five valves. A key to the species of French Guiana and the IUCN status Least Concern (LC) are proposed.

“…St.-Hil.) é uma planta pertencente à família Menispermaceae (Braga, 1989) e a atenção que lhe tem sido dada se deve basicamente às suas propriedades medicinais (Barbosa Filho et al, 1997 a.b;Rodrigues, 1989;Lorenzi, 1982). Contudo, recentemente, esta planta tem sido encontrada freqüentemente infestando canaviais localizados nos municípios de Jaboticabal e Pradópolis, SP.…”
