Gilbertiodendron (Leguminosae-Caesalpinioideae) is an endemic tropical African genus of ca. 30 species, most of which are trees of primary forest. The highest concentration of species and morphological variation is found in the Guineo-Congolian region, particularly in Gabon. One of those species is G. grandistipulatum, which is easily recognized by its stipules (up to 18 cm long) and flowers (adaxial petal up to 12.5 × 14 cm). The taxonomy, habitat and distribution of G. grandistipultaum are discussed, extending its known distribution to Congo. A full description, distribution map and two illustrations are provided for the first time for this species. |
