A phylogenetic analysis ofDuguetia (Annonaceae) based on morphological data

In this paper we present a phylogeny based on a study of the general morphology of 61 of the ca. 80 species ofDuguetia. Analyses were performed with PAUP. The resulting phylogeny is compared with the classification ofDuguetia as suggested byFries (1934, 1937, 1939, 1959). The results are partly corresponding withFries's classification. SectionAlcmene includingD. rionegrensis, and sects.Geanthemum, Synsepalantha, andCalothrix withoutD. uniflora, are upheld by this analysis. It is concluded that sect.Xylopipetalum should be united with sect.Duguetia. Before other taxonomic decisions at the section level can be made, more solid data must be available. Most dissimilarities found are considered to be not strong enough to propose alterations.Studies inAnnonaceae XXIII. For 22nd part seeZuilen & Maas (1994).
