Última Evolution and phylogenetic importance of endocarp and seed characters in Viburnum (Adoxaceae) Naturalis Jacobs, B.; Donoghue, M.J.; Bouman, F.; Huysmans, S.; Smets, E.F.. Recent phylogenetic analyses based on molecular markers have resulted in a solid phylogeny of Viburnum with 12 well-defined clades. This has allowed us to focus on character evolution, endocarp and seed characters in particular. Members of Viburnum bear drupes that differ considerably between clades. Characters such as pyrene shape and grooving, number of fibrous layers, seed coat anatomy, and seed rumination are phylogenetically highly valuable. Our results largely agree with the results based on molecular data and provide several additional insights. The position of V. clemensae as sister to the rest of Viburnum is supported by several characters. The early diversification of V. clemensae might explain its highly derived features. Furthermore, our... Tipo: Article / Letter to the editor Palavras-chave: Viburnum Adoxaceae endocarp seed evolution phylogeny 42.43; 42.58. Ano: 2008 URL: http://www.repository.naturalis.nl/record/449561 Evolution of fruit and seed characters in the Diervilla and Lonicera clades (Caprifoliaceae, Dipsacales) Naturalis Jacobs, B.; Lens, F.; Smets, E.. Background and Aims: The Diervilla and Lonicera clades are members of the family Caprifoliaceae (Dipsacales sensu Donoghue et al., 2001, Harvard Papers in Botany 6: 459–479). So far, the intergeneric relationships of the Lonicera clade and the systematic position of Heptacodium remain equivocal. By studying fruit and seed morphology and anatomy, an attempt is made to clarify these issues. In addition, this study deals with the evolution of fruit and seed characters of the Diervilla and Lonicera clades with reference to allied taxa. Methods: Light and scanning electron microscopy were used for the morphological and anatomical investigations. Phylogenetic analyses were carried out by applying the parsimony and Bayesian inference optimality criteria....
