Jumellea is an orchid genus with 55 species native to Madagascar, the Comoros, the Mascarenes, and eastern Africa.
Taxonomy It was described by Rudolf Schlechter in 1914. Etymology It is named after Henri Lucien Jumelle, a French botanist.Genaust, Helmut (1976). Etymologisches Wörterbuch der botanischen Pflanzennamen Phylogeny Jumellea is proven to be monophyletic.Andriananjamanantsoa, H. N. (2016). "Systématique évolutive et biogéographie de Angraecum (Orchidaceae, Angraecinae) à Madagascar." Jumellea is the sister group to Aeranthes. Both genera together are the sister group to Angraecum:Farminhão, J. N., Verlynde, S., Kaymak, E., Droissart, V., Simo-Droissart, M., Collobert, G., ... & Stévart, T. (2021). "Rapid radiation of angraecoids (Orchidaceae, Angraecinae) in tropical Africa characterised by multiple karyotypic shifts under major environmental instability." Molecular Phylogenetics and Evolution, 159, 107105.Perez-Lamarque, B., Maliet, O., Pichon, B., Selosse, M. A., Martos, F., & Morlon, H. (2022). "Do closely related species interact with similar partners? Testing for phylogenetic signal in bipartite interaction networks." Peer Community Journal, 2.
Angraecum evolved into a separate lineage about 9.12 million years ago, and the genera Jumellea and Aeranthes separated about 9.55 million years ago. This means these genera date back to the Miocene. Species

Distribution and habitat It is native to the Comoros, Kenya, South Africa (KwaZulu-Natal, Northern Provinces), Madagascar, Malawi, Mauritius, Mozambique, Rodrigues, Réunion, Tanzania, and Zimbabwe.
Ecology Jumellea exhibits the typical adaptions to pollination by hawk moths. However, also auto-pollination is known to occur in Jumellea stenophylla.Micheneau, C., Fournel, J., Gauvin-Bialecki, A., & Pailler, T. (2008).
