Pyrenacantha gossweileri (Exell) Byng & Utteridge is a species in the Icacinaceae family, native to Cabinda. The species was formally described in 2014. It is characterized by its ovoid fruit with an inflated cap at the apex, a strigose epicarp with yellow, granular-hairy structures, and a mesocarp 130–140 µm thick when dry. The endocarp is brown, ovoid to globose, with a sharp keel and a pitted, ridged outer surface. The endocarp wall is 423–498 µm thick, composed of three cell layers.
Description
The fruit of Pyrenacantha gossweileri is ovoid, with an expanded cap covering half the fruit length. The epicarp is covered in yellow simple hairs with granular ornamentation. The mesocarp measures 130–140 µm in thickness when dry. The calyx is not persistent. The fruit dimensions are 16.0–16.8 mm in length, 11.3–16.0 mm in width, and 7.5–12.0 mm in thickness. The endocarp is brown, ovoid to globose in lateral view, and lenticular in cross-section. It has a sharp keel along the symmetry plane and an acute, asymmetrical apex. The outer surface is pitted and ridged, with elongate pits (0.5–1.7 mm) and associated elongate-flattened tubercles. The endocarp wall, excluding ridges, is 423–498 µm thick and consists of three cell layers.
