To my knowledge there were only twelve plants of this that came into the United States from Panama. It is reminiscent of the Dicranopygium from Kuna Yala. This species came in as a group of seedlings and it seems as if only one was ever sold, and a handful of others were distributed among friends. I received two of these plants, and have now had them about three years. They were more or less the same size at first. Per the recommendation of Charlot Teng I switched one of the seedlings to potting soil (they had both been potted in sphagnum). After a year or so in potting soil, the plant became more robust and significantly taller. Recently I transferred the larger seedling to clay substrate in a terrarium and after a few months it looks as if it’s going to flower! yay! The second seedling was also transferred to clay. You can see the difference in size between the two.
And the flower! It lasted less than 24 hours, but I have heard that it often flowers a few times over a period of months.
