Triotosiphon gnoma

I purchased this plant as Masdevallia or Acinopetala minuta, but it does not appear to be that species and I am pretty certain it is Masdevallia or Triotosiphon gnoma instead.  The plant is only 2 cm tall and the flowers are nearly that long.  Because the plant is so small and the flowers carried on such short peduncles, they lie close to the surface of the moss in which the plant is growing.  Seen close-up the flowers are nearly transparent and the inner parts of the flower are visible through the sides.  My plant is still very small, since it was only a couple of leaves when I got it and nearly died subsequently.  The species is from Ecuador.
