The dark purple flowers are long-pubescent within. The obtuse petals and lip are small. Most characteristic are the small, erect, subquadrate lobes of the lip. THe anterior corner of the truncate apex is slightly proplonged. A prominent pair of lamellae occupy the middle third of the lip and a small pair of adjacent lamellae are present at the base."
