I found this orchid some years ago during a hike in the Rio Abajo forest. The orchid was growing over several living trees, on stumps and on some places crawling over the fallen branches and the leaf litter. In this small spot of the forest the stems of this orchid were all over the place. However my enthusiasm over finding this plant was tempered by the fact that I could not find any evidence that the stems that were under eye height, and therefore accessible to being photographed, had ever bloomed. Some of the stems were fifty or more feet up in the trees and I surmised that it was there, where the plant was exposed to the greatest sunlight, that the flowers were produced.
I visited the plants every year on what I suspected was its blooming season, but I could not locate any evidence that it had bloomed. Then about two weeks ago, I noticed that some of the stems were producing inflorescences, luckily a few were low enough that I could take photos of the flowers.
The flowers last a single day, I have noticed that the inflorescences have one flower open at a time. The inflorescences attract ants, you can see them around the bases of the flower buds. The inflorescences are not uniformly distributed through the stems. Almost all of the inflorescences I found were on the stems that were getting the most sun. None of the stems that were growing on the deep shade had flowers and neither did the undersized stems that were crawling on the ground.
This orchid is used to produce commercial vanilla, it is native of Mexico. This orchid seems to be doing quite well on its own. I have only found a single seedling, it growing at the base of a huge teak tree. Unfortunately, the small plant didn’t survive when snails attacked it. All the other plants I have seen have been either large adults or pieces that have fallen from the canopy and are starting to produce roots and climbing growths.

This is the second year this orchid has bloomed for me. The plant has produced more flowers and of a slightly larger size than last year. This orchid is still young and has a lot of potential. It will be interesting to see if these particular clones have inherited the capacity of the Enc. bractescens parent to produce many flowers.
This is one of my smallest Dendrobium species. The cane grows just a few inches in spite of all my efforts to try to see if it will produce larger canes. I grow it exactly like my Dendrobium anosmum, it also receives the same light conditions. It blooms every year with a few flowers on the tip of the canes. I suspect that my local conditions are a bit too warm for this species and this translates into less vigorous growing.
