Den. tobaense belongs to section Formosae or Nigrohirsute—a reference to the tiny black hairs that cover the canes and underside of the leaves on this species.
Flowers are waxy and long-lasting, with a distinctive spear-like lip.
Grow in dappled light and keep moist but well-drained, only allowing the plant to dry slightly between waterings. Reduce water and fertilizer somewhat during the cooler months.
