    Studies in Annonaceae. IX. New species from the Neotropics and miscellaneous notes (1988)
    In:  Miscellaneous publications of the University of Utrecht Herbarium vol. 3 no. 1, pp. 243-282
    Details
    Publication Date: 2024-01-12
    Description: This paper follows upon an earlier paper in the series \xe2\x80\x9cStudies in Annonaceae\xe2\x80\x9d (Maas et al. 1986). Twelve new species are described, viz. 2 in Duguetia, 1 in Ephedranthus, 5 in Guatteria, 2 in Hornschuchia, 1 in Tetrameranthus, and 1 in Unonopsis. A new combination is made in Enicosanthellum. Some amendments and additions to the revision of Tetrameranthus (Westra 1985), including an updated key, are given. Monocarpia euneura Miq. appears to have priority over M. marginalis (R. Scheffer) James Sincl. Additional collections have been made of the rare species Bocagea longepedunculata Martius, Xylopia crinita R.E. Fries, and Xylopia excellens R.E. Fries. Attention is drawn to several recent collections from Bahia, Brazil, which are perhaps referable to Unonopsis stipitata Diels. H. Le\xc3\xb3n, Popay\xc3\xa1n, and D. S\xc3\xa1nchez S., Medell\xc3\xadn, contributed to three of the new species.

    Flowers of annonaceae: Morphology, classification, and evolution (1992)
    In:  Blumea. Supplement vol. 7 no. 1, pp. 1-218
    Details
    Publication Date: 2024-01-12
    Description: The present paper describes the diversity in floral characters of Annonaceae and their distribution over the family, and discusses their value for classification and generic delimitation. Flower morphology predominated historical classifications of this family since Hooker & Thomson (1855) introduced floral characters to divide the Asiatic genera into a number of tribes. Since then, several taxonomists presented a classification of the Annonaceae using floral characters, which classifications, however, are generally felt as unnatural. A survey of the flower morphology of all genera reveals a reticulate distribution of floral character states. Classification of the genera, as presented in this study, learns that floral characters different from those in previous classifications should be used if one aims at a better correlation with non-floral features. The chromosome number in this respect turned out to be an important character. Classification of the neotropical genera is relatively easy compared with classification of the African and Asiatic genera. Current genus delimitations in many cases are disputable. The functional aspects of the flower morphology are discussed in connection with a literature survey of the results from field studies on flower biology of Annonaceae. Some remarks on evolutionary aspects are added.
