    Studies in Annonaceae. IX. New species from the Neotropics and miscellaneous notes (1988)
    In:  Miscellaneous publications of the University of Utrecht Herbarium (1572-6592) vol.3 (1988) nr.1 p.243
    Details
    Publication Date: 2015-05-08
    Description: This paper follows upon an earlier paper in the series “Studies in Annonaceae” (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. León, Popayán, and D. Sánchez S., Medellín, contributed to three of the new species.

    Floristic observation on forest types in Western Suriname. I (1971)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.350 (1971) nr.1 p.269
    Details
    Publication Date: 2015-05-08
    Description: Some rain and savanna forests of western Suriname (Corantijn R., Winana Creek; Upper Marataka R.; Upper Nickerie R;) were studied and their composition was compared with that of forests of other parts of Suriname and Guyana. The savanna forests of western Suriname proved to be much related to Guyanan ( Walabaand Dakama-) savanna forests as described by Davis & Richards (1934) and Fanshawe (1952). On the other hand, there was less relationship as regards rain forests of western Suriname when compared with ones of Guyana and other parts of Suriname, except for the Demerara greenheart forest of the Upper Marataka R., which was closely related to the Demerara greenheart forests of Guyana as described by Davis & Richards (1934). In addition an upland rain forest was studied near Blanche Marie falls, Upper Nickerie R., which proved to be very much like that of the Stofbroekoe Mts., eastern Suriname, as described by Schils (1960). Species/area curves for some rain and savanna forests are given. The geographical distribution of some common western Surinam tree species was studied; of the seventeen species studied one was endemic for Suriname. An annotated list of all species of trees and palms occurring in the explored areas is provided.

    A scanning electron microscopic study of the seed coat structure of Curtia Chamisso & Schlechtendahl and Hockinia Gardner (Gentianaceae) (1983)
    In:  Miscellaneous publications of the University of Utrecht Herbarium (1572-6592) vol.1 (1983) nr.1 p.33
    Details
    Publication Date: 2015-05-08
    Description: The six species of Curtia, including a hitherto undescribed species published here, as well as the monotypic genus Hockinia can be distinguished from each other by the seed coat structure. The anticlinal walls and the cuticle provide the most useful information. Curtia tenuifolia appears to be a complex species, but subsp. tenella can be readily separated from this complex by the seed coat structure. Heterostyly has been found in C. tenuifolia subsp. tenuifolia, C. obtusifolia, and Hockinia montana, but differences in seed coat structure can not be correlated with long-, short-, and equal-styled flowers. The differences in seed coat structure, the length of the seeds, and the number of cells per seed plead for maintaining Hockinia (closely related to Curtia) as a distinct genus. One new species of Curtia is described and a new combination is made.

    Project Systematics of Annonaceae (1983)
    In:  Mededelingen van het Botanisch Museum en Herbarium van de Rijksuniversiteit te Utrecht (2352-5754) vol.516 (1983) nr.1 p.1
    Details
    Publication Date: 2015-05-08
    Description: Recently a multidisciplinary investigation program on the systematics of Annonaceae was started at Utrecht with special emphasis on the Neotropics. This project will be carried out largely within the framework of the UNESCO-project Flora Neotronica. The first goal is to provide a modern classification of the family as a whole, the second is the publication of a series of monographs for Flora Neotropica. The project has been planned and started in close consultation with leading botanists on the Neotropical flora. The Annonaceae are a family of pantropical distribution with between 2000 and 2500 species in ca. 130 genera as presently understood. In the Neotropics the family is represented by ca. 750 species and 35 genera. It is a family of trees, shrubs, and lianas. Its place is within the order of the Magnoliales and its supposedly closest relative is the family of the Myristicaceae. The Annonaceae, although generally considered primitive in many features, nevertheless offer a number of specialized features as well This makes it a promising object using various kinds of comparative morphological, karyological, and anatomical data. Besides, many species are of medicinal or commercial value, such as various species of Annona and Rollinia, the fruits of which are commonly eaten in most countries of Central America and South America; the Soursop (Annona muricata) is widely cultivated throughout the tropics.
