Diagnosis

Imprints of small fruits, obtriangular in outline, with four horns; fruit 7– 12 mm high (including neck), width at the level of the upper horns 15–23 mm; fruit about 1.9–2.7 times as wide as high; fruit head pronounced, 4–6 mm long, its upper end bearing a well-developed straight cylindrical neck; neck 1.2–2.0 mm long and 1.5–2.0 mm broad, corona lacking; apical aperture with a ring of upward-pointing hairs; surface of fruit head and neck finely ribbed; upper horns solid, 5–9 mm long, narrowly triangular in outline, gradually attenuated into straight elongate, thin, spinelike tips, widely spread or ascending (50°-80°), probably with a smooth surface except for the at least 5 mm long, retrorsely barbed spines (harpoons), base of the upper horns attenuate gently into the upper surface of the fruit or sometimes slightly raised at the base; no mat areas present at the base and/or apical part of the upper horns; lower horns at least slightly retrorse, straight, relatively narrow, not less than 4 mm long, inserted (1/4) 1/3 (2/5?) from the fruit’s base; fruit frame well developed; on the fruit frame between the bases of the upper and lower horns, small tubercles are developed, at least up to 0.3 mm long; lower part of the fruit body regularly obtriangular in outline, with slightly to distinctly rounded base (no peduncle adherent), its surface, on one side only, covered with at least three protruding longitudinal ribs; basal ring not visible; basal scar small, probably at least 0.3 mm in diameter.
