The Connaraceae : a taxonomic study with special emphasis on Africa

C. C. H. JongkindIn the general part of this work the author of this thesis treats the leaves, flowers and fruits of Connaraceae. Additional chapters reflect upon the phylogeny of the genus Rourea , the phytochemistry of the family, and the relationship of Connaraceae with other families.In the taxonomic part a description of the family is presented together with keys to the genera. A revision of the genera Agelaea , Manotes , and Rourea is presented with special emphasis on Africa, including descriptions of the genera and differential keys to the species.In the revision of the genus Agelaea six species are recognized including the Asiatic species.Manotes is only found in Africa and comprises five species.The genus Rourea is revised for Africa only, twelve species are recognized for this area. The American and Asiatic species are studied but not revised. New combinations are made for American and Asiatic species that are transferred to this genus. The American species are classified into clusters. In this work Rourea also includes Bernardinia , Byrsocarpus , Jaundea , Roureopsis , Santaloidella , Santaloides , Spiropetalum , and Paxia , formely recognized as separate genera.The treatment of the African species comprises full synonymy, literature, diagnosis, a distribution map, and ecological notes. In most cases an illustration is presented as well.The author studied and collected most species of Agelaea , Manotes , and Rourea on location in the rain forest in Gabon.R. H. M. J. LemmensIn the general part of this work the author of this thesis treats the geography, habit, morphology of stems and branches, and inflorescences of Connaraceae. The phenomenon of heterostyly, its expression and evolutionary developments are dealt with in a separate chapter. Additional chapters reflect upon the phylogeny of the genera within the family and on mutual relations of the species in the genus Cnestis. The, author has assembled what is known about the pollen morphology, and provides supplementary original information.In the taxonomic part a revision of the genera Cnestis , Connarus , and Ellipanthus is presented, with special emphasis on Africa, including descriptions of the genera and differential keys to the species. Additional keys are presented for plants that are either exclusively flowering or fruiting.In the genus Cnestis 13 species are recognized, including the Asiatic C.palala and two new species, C.bomiensis and C. uncata. Compared to Schellenberg's monograph on Connaraceae (1938) the number of species is extensively reduced.Connarus comprises seven species in Africa, including the new species C.gabonensis , while Ellipanthus has two African species, of which one was collected only once on Madagascar.The treatment of each species comprises its full synonymy, literature, diagnosis, an illustration, a distribution map, and ecological and botanical notes.The author studied and collected five species of Cnestis, and two species of Connarus on location in the rain forest in Gabon

A reconsideration of Ellipanthus (Connaraceae) in Madagascar and continental Africa, and a comparison with the species in Asia.
