Very distinct in flower from the other subspecies and also occupying a somewhat disjunct distribution.   The external markings are very variable, although almost always attractive.  

In cultivation this is a more difficult plant to maintain, requiring a drier summer rest.   This species has been hybridised in cultivation with subspecies atticus to produce cultivar 'Hubert Edelsten' which is a good garden plant.

This plant has very variable markings on the exterior of the outer petals.   Several forms are pictured below.
