Pedicel of fruit 20 - 44 mm long by 3 - 7 mm diam., weakly longitudinally rugulose, glabrate; torus of fruit ellipsoid to broadly pyriform, 7 - 15 mm diam. x 8 - 12 mm long, grey-brown. Monocarps up to 18 per fruit, green (rarely with orange or vinaceous tinge) in vivo, dark brown when dried, weakly (to strongly) recurved-falciform, (1.9) 6.0 - 8.6 cm by 0.7 - 2.2 cm, torulose, minutely verrucose, glabrate or with a few scattered hairs, base sub-sessile or short-stipitate, stipe 1 - 11 mm long, 2 - 6 mm thick, apex rounded or sometimes short-beaked. Seeds 1 - 15 per monocarp, 15 mm long by 13 mm wide by 10 mm thick, arranged in a single [or two irregular?] rows, flattened-ellipsoid, pitted, with spiniform ruminations (fig. 3) and raphe / antiraphe sunken in a circumferential groove.	en	Marshall, Andrew R., Couvreur, Thomas L.
