Nephrangis filiformis is a rare epiphytic African orchid growing in wet upland tropical forest. In all recent floristic treatments and botanical websites its distribution is reported as Liberia, Côte d'Ivoire [Ivory Coast], Democratic Republic of the Congo (DRC), Rwanda, Burundi, Zambia, Uganda, Kenya and Tanzania. Here I show that its alleged occurrence in Kenya and Tanzania is based on a misidentification in a book published in 1968, which has been carried over ever since. Since there is no physical or photographic evidence to the contrary, I conclude that Nephrangis filiformis does not occur in Kenya or Tanzania.
