This is a wonderfully vigorous plant with nice fleshy dark green leaves and intense chocolate colored flowers. It blooms every winter for me, and this year it started sometime before the new year and just now finished after almost five months of blooming on six inflorescences. The inflorescence grow out from the midrib at mid leaf and hold a long string of nodding flowers measuring about a centimeter tall. It is a small to medium sized, warm to cool growing growing epiphyte from Mexico to Northern Venezuela where it grows at altitudes ranging from 800 to 1800 meters. I grow mine potted, although not much media will fit in the pot anymore which instead is completely full of roots. It has an amazing root system! It enjoys humid but not wet conditions under medium/ low light in the cool vivarium.
