- Diagnosis
- Prolate drupes composed of a conspicuous
central vascular bundle, surrounded by an endocarp that
contains five locules and five lacunae. Endocarp conspicuously
ornamented, appearing star shaped, T shaped, and with radiating
ribs and spines, forming deer antler–like outlines in transverse
and/or longitudinal sections. Mesocarp thick and composed of
thin-walled parenchyma and sporadic sclereids. Locules single
seeded, radially arranged near the center of the drupe, elliptical
in transverse section and elongated, straight to curved as seen
in longitudinal section. Each locule surrounded by a locular envelope.
Lacunae alternating with the locules, radially arranged and
variously shaped as seen in transverse section; lacunae open distally,
not fully enclosed by endocarp tissue. Each lacuna with a
ventral longitudinal row of minute orbicules. Drupes with recessed
internal bilabiate germination (i.e., valves hidden within
the spongy tissue) in which the locular envelope opens along an
apical keel that is recessed within a pore of the endocarp wall.
