Resume In Benin, people have a rich ethnobotanical knowledge of plant species, reflecting the cultural and ecological diversity of their environment. Several studies were focused on the question of how valuable are plant species for local com- munities. However, there has been very little research interest in the orchid species in spite of the importance of orchids in the livelihood of the local people. This study examined the use and differences in knowledge of local people of orchids in the Sudanian zone of Benin. An ethnobotanical study was conducted amongst the four main socio-economic and ethnic groups from six villages around the Pendjari Biosphere Reserve in Benin. One hundred and sixty people participated in this study. Data were gathered using semi-structured individual interviews and analysed using quantitative ethnobotanical methods. 29 different types of use were recorded and can be grouped into four main use categories: medicinal, veterinary, spiritual and food. There were differences in orchid utilization among the ethnic groups, gender and age. The knowledge of orchid uses was significantly affected by the ethnic group and the age of the respondent. Unlike young educated generations, most adults and elders, especially women, had a more comprehensive knowledge of orchid uses. Calyptrochilum christianum, the most used orchid, was mentioned in more than 50% of the types of orchid use. The Gourmantché and Waama tribe had more knowledge on orchid use whereas the Berba tribe had less knowledge. Three orchid species (Habenaria cirrhata, Eulophia horsfallii and Nervilia bicarinata) were reported as food. Orchids had low use value ranging from 0.01 (Eulophia spp) to 0.2 (C. christianum). The controlled access to the biosphere reserve and rural exodus can explain the lack of indigenous know- ledge transfer of orchid use and value from elders to the young generation.
