Other material MADAGASCAR ��� 1932; J. Leandri 468; P [MNHN-P-P04472110] ��� 1996; C.C.H. Jongkind 3385; P [MNHN-P-P05279694] ��� 1997; C.C.H. Jongkind 3696; P [MNHN-P-P05274867]. Description FRUIT. Globose, brown when mature. Epicarp strigose, with yellow simple hairs with granular ornamentation, finely ridged when dry, revealing the underlying reticulum of endocarp ridges. Mesocarp 88���111 ��m thick when dry. Length 11���17 mm, width 11.3���15.0 mm, thickness 10���12 mm. ENDOCARP. Cream, globose in lateral view and transverse section, length ca 11.5 mm, width ca 10.9 mm, thickness ca 9.2 mm. Keel thin and delicate, surrounding the endocarp in the plane of symmetry, with the thicker margin containing the primary vascular bundle embedded within the endocarp wall. Apex slightly asymmetrical; base rounded, symmetrical. Outer surface of the endocarp ridged with two types of ridges. The primary ridges comprise three main longitudinal ridges, two of them spanning from the apex to the base. Primary ridges thin, rounded and forming a sparse diffuse pattern. Secondary ridges thin and sharp, delimiting a dense reticulum enclosing numerous areoles. Endocarp possessing a symmetrical pair of pores positioned eccentrically and subapically on the endocarp faces. Vasculature of the endocarp resting on ridges. Endocarp wall 317���338 ��m thick excluding ridges (340���426 ��m thick including ridges). Endocarp wall with three cell layers: outermost layer with 3���11 rows of isodiametric to anticlinally oriented cells, cells 23.7���44.0 ��m in width, followed by a layer with 3���9 rows of periclinally oriented cells, cells 20���27 ��m in width, innermost layer with one row of periclinally oriented cells, cells 12���18 ��m in width, covering the inner endocarp surface with regularly spaced and rounded papillae; papillae 12.3���18.0 ��m (av. 14.9 ��m) in diameter, ca 448 papillae per 0.25 mm 2. Locule lacunate.
