Dryadella barrowii

I purchased this as Masdevallia minuta and when it bloomed it proved to be something entirely different, though the genus Dryadella was once included in Masdevallia.  After a lot of searching I've come up with a tentative identification since it seems to fit best the descriptions of Dryadella barrowii, also from Ecuador.  The leaves are about 8 cm and the flowers have a spread of 2 cm.  Like the rest of the Dryadellas it produces a lot of flowers when it blooms.
