Nomenclature etc. SAPOTACEAE. Trade and local names: aningré, longhi (DE, FR), aninguéri, anigré, agnégré (FR), aningeria (GB), kali (DE), grogoli, koandio, osam (CI), mukali (AO), mukalla (CG), inon, agwa (NG). Not protected under CITES regulations.
Description based on 1 (1 specimen). Tree. Geographic distribution: tropical Africa.
General. Heartwood basically white or grey to yellow. Sapwood colour similar to heartwood colour. Density 0.55–0.65 g/cm³.
Vessels. Wood diffuse-porous. Vessels arranged in diagonal and/or radial pattern (radial), in multiples, commonly radial rows of 4 or more. Average tangential vessel diameter 45–73–100 µm. Average number of vessels/mm² 17–23. Perforation plates simple. Intervessel pits alternate, average diameter (vertical) 3–5 µm. Vessel-ray pits with distinct borders and with reduced borders or apparently simple, similar to intervessel pits, horizontal to vertical, of uniform size or type and of two distinct sizes or types in the same ray cell, of the same type in adjacent elements and unilaterally compound and coarse. Tyloses in vessels present, thinwalled.
Tracheids and fibres. Fibres of medium wall thickness. Fibre pits mainly restricted to radial walls, simple to minutely bordered.
Axial parenchyma. Axial parenchyma banded. Axial parenchyma bands marginal (or seemingly marginal), reticulate, fine, up to three cells wide.
Rays. Rays 9–14 per tangential mm, multiseriate (also if only few), (1–)2–3 cells wide. Rays with multiseriate portions as wide as uniseriate portions present. Rays composed of two or more cell types (heterocellular). Heterocellular rays with square and upright cells restricted to marginal rows, mostly 2–4 marginal rows of upright or square cells and with more than 4 marginal rows of upright or square cells.
Mineral inclusions. Crystals present, in form of crystal sand. Crystal sand observed in vessels only. Silica present, as grains, in rays cells. Silica particles always embedded in reddish brown gums; larger in marginal cells, smaller in procumbent cells.
Physical and chemical tests. Froth test positive.
