This species has never yet been described by authors. It is a bush with round branches, triangular at their extremities, and covered with a brownish bark. The leaves are opposite, supported by short and hairy petioles; their limb is oval, reticulate, covered with stiff hairs, and traversed on its lower surface by five thick almost parallel nerves running from the base to the summit of the leaf. The flowers are sessile supported by terminal axes. We employ the leaves.
