Morphology

Members of this species generally develop as woody climbing shrubs or lianas. The specific epithet aculeata indicates the presence of prickles, serving as a defensive adaptation in its natural habitat. Its foliage is notably leathery, a characteristic that led to some of its earlier botanical synonyms such as Seguieria coriacea.
