Morphology
This species displays a subshrubby growth habit with branched stems covered in fine trichomes.
The leaves are arranged alternately, showing an ovate outline with entire margins and a slightly pubescent surface. The small, inconspicuous flowers feature a campanulate calyx that undergoes significant modification during fruiting.
During the post-fertilization stage, the accrescent calyx expands dramatically, forming an inflated, egg-shaped protective envelope around the developing globose berry.
Interesting facts
The specific epithet oocarpa translates to "egg-fruited," referencing the characteristic shape of the inflated calyx enclosing the berry.
Like many members of its genus, this plant synthesizes secondary metabolites known as withanolides, which are studied for their chemical complexity. The species serves as an important indicator of localized microclimates within Cape Verde's volcanic ecosystems.
