Flower Size 1/16" [7 mm]
A miniature epiphyte found in southern Brazil on branches and trunks of trees in cool, moist montane forests with terete, fleshy, narrow leaves that are channeled above and short [3 cm], erect, few [3 to 5] flowered inflorescence arising from the apex of stalk occuring in the summer and winter. I grow mine in a pot with sphagnum moss in a shaded location with some dappled sun, warm to cool temperatures and ample water to keep it moist at all times.
