Lannea hessenensis was named by Collinson et al. (2012) [Fruit usually elliptical to nearly circular in lateral outline, long axis 8.5–13 mm, short axis 7.2– 10.0 mm (n = 5). Surface smooth, outer fruit wall thin (0.1–0.2 mm). Outer endocarp surface covered with fine swirling fibres and basal attachment scar. Beneath this ornamentation are massive strands 0.3–1 mm wide composed of fibres which curve and branch enclosing 6–8 large deep smooth depressions (most frequent surface morphology encountered, outer layers having been lost). Curved germination slit frequently visible at apical end of fruit. Basal attachment scar circular, 2.4 mm wide, surrounded by a ring 0.2 mm thick; fruit faceted adjacent to the attachment.]. It is not extant. Its type specimen is Holotype SM.B Me 4882, a seed/fruit.
