Lannea discolor leaves may also be darker on their upper surfaces as seen here.
Spaced pairs of pale, lateral veins ascend from the midrib to the margins, not quite reaching them. Veining is still visible on the lower surfaces also, in spite of the presence of the dense whitish hairs. White hairs also cover the rachis and leaf petiole.
The specific name, discolor, comes from the Latin meaning different colours, referring to the colour contrast between upper and lower leaflet surfaces (Coates Palgrave, 2002; Schmidt, et al, 2002; Pooley, 1993).
