What are the morphological characteristics of this plant?

Gouania leptostachyya has a woody, scrambling shrub habit characterized by slender, arching branches and small, elliptic to lanceolate leaves that are typically arranged alternately along the stems. The foliage is generally leathery in texture with smooth or slightly serrated margins and a dull green coloration. Its reproductive structures consist of small, inconspicuous flowers that emerge from the leaf axils to produce distinct, woody pods. These elongated fruits eventually split open to reveal seeds that are essential for the plant's dispersal within its native habitat. The overall architecture of the plant allows it to weave through surrounding vegetation in scrubland environments.
