Abstract
Background and aims – The treatment of the Anacardiaceae for the Flore du Gabon had to deal with three obscure Lannea names described from South Cameroon, namely L. glabrescens Engl., L. longifoliolata Engl. & Krause, and L. zenkeri Engl. & Krause. The type material of two of these names had been lost at Berlin. The paper aims at establishing their identity.
Methods – Normal practices of herbarium taxonomy have been applied to study the available herbarium material from BR, BRLU, HBG, K, MA, P and WAG. The relevant collecting data are stored in the Naturalis Biodiversity Center, Leiden, Section Botany. Arcgis 10.2.2. was used to produce the distribution map.
Key results – Lannea longifoliolata and L. zenkeri proved to be synonyms of L. welwitschii (Hiern) Engl. and L. glabrescens represents a hitherto neglected distinct species. Lannea glabrescens is neotypified and provided with a description and an illustration. Its distribution is mapped. A key is given to distinguish the two species of the western central African forest. Lannea longifoliolata and L. zenkeri are synonymised under L. welwitschii and typified.
