Description

FRUIT. Ovoid. Epicarp strigose with yellow uncinate hairs, shriveled when dry, revealing the underlying reticulum of endocarp ridges. Mesocarp 143–240 µm thick when dry. Length 8–17 mm, width 7–12 mm, thickness 6 mm.

ENDOCARP. Ovoid in lateral view, length ca 8 mm, width ca 7.8 mm, thickness ca 3 mm. Apex slightly asymmetrical, acute in lateral view, with subapical pore. Outer surface of the endocarp pitted and ridged. Ridges rounded and thin to thick, with three main longitudinal ridges; the median ridge running from the base up to ¾ of the endocarp length, the two lateral ridges running from the apex almost to the base. The two lateral ridges are each connected with some transverse ridges; transverse ridges free or connected with the keel. Pits large (0.4–0.9 mm in diameter), exclusively circular and organized in longitudinal lines, 3–5 pits longitudinally, 4 pits transversally with one pit between median ridge and lateral ridges, and one pit between lateral ridges and the keel (ca 17–19 pits per face). Pits associated with bullate tubercles, ca 400 µm in length inside the endocarp. Endocarp wall ca 170–270 µm thick (with and without ridges; the ridges are mainly formed by a fold of the wall rather than by extra thickening). Endocarp wall with three cell layers: outermost layer with 2–4 rows of isodiametric cells, cells 13.0– 22.7 µm in diameter, followed by a layer with ca 5 rows of periclinally oriented cells, cells 8.5–17.7 µm in width; innermost layer with one row of periclinally oriented cells, cells 8.6–15.4 µm in width, covering the inner endocarp surface with regularly spaced and rounded papillae; papillae 12.6–16.0 µm (av. 14 µm) in diameter. Locule lacunate.
