Reichantha striatella

A small species that blooms faithfully and prolifically every fall for me is Reichantha or Masdevallia striatella from Ecuador.  The small, though attractive, flowers are 1.5 cm and are held on more or less upright spikes just above the foliage.  The plant is 8 cm and is easy to grow.  Mine is in a plastic net pot in sphagnum moss and is watered nearly every day with an occasional very light dose of fertilizer.
