English: This figure gives a visual impression of the species richness of the genera belonging to the subtribe Angraecineae of the tribe Vandeae within the orchid family Orchidaceae. The genera listed in the following study are included:

Chase, M. W., Cameron, K. M., Freudenstein, J. V., Pridgeon, A. M., Salazar, G., Van den Berg, C., & Schuiteman, A. (2015). "An updated classification of Orchidaceae." Botanical journal of the Linnean Society, 177(2), 151-174.

Updated species richness data was acquired from the following verifiable, reliable, published source: POWO (2022). "Plants of the World Online. Facilitated by the Royal Botanic Gardens, Kew. Published on the Internet; http://www.plantsoftheworldonline.org/ Retrieved 20 September 2022."

The genera, which were not accepted by the Royal Botanic Gardens Kew as of September 2022 were not included. Thus, the following genera are not included in the diagram: Cribbia Senghas, Distylodon Summerh., Margelliantha P.J.Cribb, Ossiculum P.J.Cribb & Laan, Rhaesteria Summerh.

This is not a work of original research, as the species richness values, as well as the synonym status of the five excluded genera, which are still listed as valid in the first source, are verifiable in a reliable, published source (Plants of the World Online of the Royal Botanic Gardens, Kew)
