The longer leaves, more numerous pairs of lateral nerves, shorter pedicels, and smaller flowers are the characteristics that distinguish P fastigiata from P. hexanthera, a closely related species. The stiff, erect, numerous branches of the inflorescence are characteristic of this species and distinguish it from the other members of this group.
