- Diagnosis
- Fruits narrow, fusiform, highly compacted, 12–19 mm long and 5–6.5 mm wide. Longitudinal ribs thin, variable in number and height, 5–6 main ribs, 0–2 lower midribs and wrinkles between each pair of main ribs. Ribs run from the base to 2/3 of the fruit length. Fruits gradually narrow to a short, rib-free base, with a short and thin pedicel, mostly not preserved. Calyx 5-lobed and hairy. Apical rostrum broad (½–2/3 the width of the fruit) at the base, abruptly narrowing at ¹/3 its length into a long, thin cone. Pericarp consists of a thick and highly coalified endocarp, covered with a thin and frequently detached external layer of meso- and exocarp. Exocarp surface hairy. Locules >2.
