Leeuwenberg 4971 (BR, K, WAG); de Wilde 3751 (WAG)
A tree of riversides but also in the evergreen and semi-deciduous forests, to 35 m and Ø 100 cm. Base with medium-sized, thick, concave buttresses; bole usually poorly shaped, short and early forked. Bark medium thick, with numerous small, brown lenticels and a characteristic yellowish brown colour, especially on the lower part of the stem, which makes the tree easily detectable. Bark scales irregular, leaving walled , shallow, more or less concentric scars, a “mussel shell pattern”. Slash dark yellow, fine-granular outside, fibrous inside; fine, wavy ripple marks visible in the sapwood. Note the twisted base of the petiolule.
