- Fruits reniform, bisymmetrical, with keel in plane of symmetry, lensoidal to nearly circular in cross section, unilocular and single-seeded. Fruit wall ornamented with closely spaced spines on all surfaces except along elliptical ridge over ventral concavity. Spines terete, 1.6 mm long. Fruit wall from which the spines arise, ca 1 mm thick, represented only by space between silica locule cast and sedimentary impression of fruit. Locule cast convex dorsally, concave ventrally, rounded over one end, narrower and pointed at other end, with large circular scar ca 1/3 of full length of locule, positioned on central portion of ventral surface. Locule cast smooth or sometimes striate, with striae running oblique to plane of symmetry. Seed coat thin, shrunken away from locule. Pseudoanacardium peruvia
