  • decaying Raphia farinifera palm trees provide a source of sodium for wild chimpanzees in the budongo forest uganda
    PLOS ONE, 2009
    Co-Authors: Vernon Reynolds, Andrew W Lloyd, Fred Babweteera, Christopher J English
    Abstract:

    For some years, chimpanzees have been observed eating the pith of decaying palm trees of Raphia farinifera in the Budongo Forest, Uganda. The reasons for doing this have until now been unknown. An analysis of the pith for mineral content showed high levels of sodium to be present in the samples. By contrast, lower levels were found in bark of other tree species, and also in leaf and fruit samples eaten by chimpanzees. The differences between the Raphia samples and the non-Raphia samples were highly significant (p<0.001). It is concluded that Raphia provides a rich and possibly essential source of sodium for the Budongo chimpanzees. Comparison of a chewed sample (wadge) of Raphia pith with a sample from the tree showed a clear reduction in sodium content in the chewed sample. Black and white colobus monkeys in Budongo Forest also feed on the pith of Raphia. At present, the survival of Raphia palms in Budongo Forest is threatened by the use of this tree by local tobacco farmers.

  • Use and Cultural Significance of Raphia Palms
    Economic Botany, 2020
    Co-Authors: Suzanne Mogue Kamga, Grischa Brokamp, Ariane Cosiaux, Abdon Awono, Susanne Fürniss, Fogoh John Muafor, Philippe Gall, Bonaventure Sonké, Anders S. Barfod, Thomas L P Couvreur
    Abstract:

    The genus Raphia (Palmae / Arecaceae) contains 22 species and represents a major multiuse resource across tropical Africa and Madagascar. Raphia species provide goods that range from food to construction material and medicine. Its species play a vital cultural role in African societies. Despite its importance, the taxonomy, ecology, and ethnobotany of this genus remain poorly understood. Here, we review the multiplicity of uses, products and cultural importance of Raphia species across its distribution. We provide a near exhaustive list of all products derived from Raphia species, classified by species and major use categories. We record nearly 100 different uses, traded and commercialized at local, regional, and national levels. Most species have several uses. Raphia wine is the most important product, followed by grubs and fiber extraction. Our review improves our understanding of the uses and cultural importance of Raphia species. If Raphia resources are managed responsibly, they will contribute to alleviate poverty, fight against hunger and conserve tropical biodiversity, especially in Africa. Le genre Raphia (Palmae / Arecaceae) comprend 22 espèces et représente une ressource multi-usage majeure en Afrique tropicale et Madagascar. Les espèces de Raphia fournissent des produits allant des aliments aux matériaux de construction, en passant par les médicaments. Ses espèces jouent un rôle culturel vital dans les sociétés africaines. Malgré son importance, la taxonomie, l’écologie et l’ethnobotanique de ce genre restent mal comprises. Nous examinons ici la multiplicité des usages des produits et de l’importance culturelle des espèces de Raphia dans toute leur distribution. Nous fournissons une liste presque exhaustive de tous les produits dérivés des espèces de Raphia , classés par espèce et par principales catégories d’utilization. Nous enregistrons près de 100 utilisations différentes, commercialisées au niveau local, régional et national. La plupart des espèces ont plusieurs utilisations. Le vin de Raphia est le produit le plus important, suivi de l’extraction des vers et de la fibre. Notre revue améliore la compréhension des utilisations et de l’importance culturelle des espèces de Raphia . Si les ressources de Raphia sont gérées de manière responsable, elles contribueront à réduire la pauvreté, à lutter contre la faim et à préserver la biodiversité tropicale, en particulier en Afrique.

  • Raphia vinifera (Arecaceae; Calamoideae): Misidentified for far too long.
    Biodiversity data journal, 2019
    Co-Authors: Suzanne Mogue Kamga, Bonaventure Sonké, Thomas L P Couvreur
    Abstract:

    Background The genus Raphia (Arecaceae/Palmae) is the most economically and culturally important genus of African palms. With over 20 recognized species, it is also the most diversified among tropical African palms. However, significant taxonomic confusion still persists in the genus. Raphia vinifera P.Beauv. is one of the first two names described in the genus, but the species has been misidentified and confused for several decades. New information We clarify the taxonomic identity of R. vinifera. We retrace the taxonomic history of the name and clarify its morphological identity using the literature and type material. We synonymize the name R. mambillensis with R. vinifera. We provide a new detailed morphological description of R. vinifera based on the study of herbarium material and field data. A distribution map is also provided. Raphia vinifera is still incompletely known, and more research should be undertaken on this species' presence and ecology, especially in West Africa.

  • Two new species of Raphia (Palmae/Arecaceae) from Cameroon and Gabon
    Pensoft Publishers, 2018

    Abstract:

    Raphia (Arecaceae, Calamoideae) is the most diverse genus of African palms with around 20 species. Two new species from Cameroon and Gabon, Raphia gabonica Mogue, Sonké &amp; Couvreur, sp. nov. and Raphia zamiana Mogue, Sonké &amp; Couvreur, sp. nov. are described and illustrated. Their affinities are discussed and the conservation status of each species is assessed. For both species, distribution maps are provided. Raphia gabonica is restricted to two small populations from central Gabon, where it occurs on hillsides on tierra firme soil, and close to small streams. Its preliminary IUCN status is Endangered, being amongst the five most threatened palm species in Africa. Raphia gabonica potentially belongs to the moniliform section. Raphia zamiana is largely distributed from south Cameroon to south Gabon and is very common. It is also a multi-used palm, from which wine, grubs and construction material are extracted and sold. It generally occurs in large stands in a wide range of ecosystems such as swamps, coastal forests on partially inundated sandy soils and inundated savannahs. Its large stature, hard to access habitat (swamps) and abundant presence might have discouraged botanists to collect it until now. Raphia zamiana belongs to the taxonomically complex Raphiate section
