- Diagnosis
- Asymmetrically oblate to mushroomshaped
drupes composed of five radially arranged locules and
five lacunae. Endocarp star shaped to pentagonal as seen in
transverse section, with a small central vascular bundle; in longitudinal
section, more or less mushroom shaped; outer surface
of endocarp ornamented with up to 10 equatorial depressions.
Locules single seeded, reaching nearly to the periphery of the endocarp,
usually unevenly developed, elliptical to circular in outline
as seen in transverse section and reniform/phalloid as seen in
longitudinal section. Lacunae radially arranged, alternating
with locules, mostly triangular shaped as seen in transverse section;
empty or filled with loose fibers. Lacunae connected to the
equatorial external depressions by a pair of channels. Each locule
topped by a distally placed simple operculum(apical stopperlike
plug) that reaches the periphery of the endocarp.
