Cecropiaceae a new family of the Urticales

Ano: 1983

URL: http://www.repository.naturalis.nl/record/534682

The problem of the correct position of the Conocepbaloideae, a subfamily of the Moraceae in Engler's system, but transferred to the Urticaceae by Corner (1962), can be satisfactorily solved by assigning the rank of family to this taxon, to be named Cecropiaceae. Diagnoses of and a key to the six genera constituting this family (Cecropia, Coussapoa, Musanga, Myrianthus, Poikilospermum, and Pourouma) are given. The classification of the Urticales and the relationship between the Cecropiaceae and both Moraceae and Urticaceae are discussed. A key to the families of the Urticales is given.

Moraceae: Ficeae

Berg, C.C.; Corner, E.J.H..

A pantropical genus of terrestrial and hemi-epiphytic trees and shrubs or climbers with a unique inflorescence (syconium, fig). This forms the basis of a unique and complex pollination system requiring flowering phenologies that make mature inflorescences highly important as food source for forest animals. Large-scale economic value is confined to production of indoor and outdoor ornamental trees. The genus, the largest of the 37 genera of the family, comprises about 735 species worldwide and 367 currently recognised in the Malesian region. The introductory part consists of chapters on distribution, ecology, classification, morphology, pollen morphology (by J.M. Langeveld & R.W.J.M. van der Ham), microscopic characters of the leaf, wood anatomy (by...

Redefinition of Ficus schwarzii and two new species of Ficus (Moraceae)

Palavras-chave: Ficus; Sect.; Oreosycea; Moraceae; Western Pacific.

Ano: 2002

Ficus schwarzii as defined by Corner proved to be too heterogeneous and has to be split up into at least two entities, the Sulawesi one still heterogeneous and the other widespread one to be described as a new species, F. rosulata. Re-examination of herbarium material led to the discovery of a new species: F. kalimantana.

Some remarks on the classification and differentiation of Moraceae

Ano: 1983

URL: http://www.repository.naturalis.nl/record/535245

With the appearance in 1889 of Engler’s treatment of the Urticales in “Die natürlichen Pflanzenfamilien” there came a pause in the interesting development of the classification of this group, which was defined, albeit somewhat vaguely, by A.L. de Jussieu in 1789 in his “Genera Plantarum” as the order Urticeae. Since the 1830’s, many, including Gaudichaud, Trécul, Miquel, Bureau, Eichler, Baillon, and Bentham, have contributed to the establishment of the Engler system which until recently has been generally accepted. An important moment in this history was the appearance of Trécul’s treatment of the then most problematical group, the “family” Artocarpeae. Trécul (1847) considered the “families” which at that time were distinguished within the “class”...
