- Diagnosis
- Fruit a globose to
oblate, five-valved, loculicidal capsule with
a thick, short pedicel and a persistent calyx
of five curved, rounded, connate sepals at the
base. Three helically arranged bracteole scars
present near base of pedicel. Pericarp composed
of two woody layers. Each valve elongate
with a median ventral septum. Valves prominently
clefted apically, forming two marginal
points directed distally upwards, separated by
a central sinus directed towards the axis. Capsule
containing a central columella that progressively
enlarges toward the apex, terminating
in a transversely expanded five-point star.
Valves lack thickened sutures.
