Every year, in January, there is a huge party in the town of San Sebastian, Puerto Rico. I was there having fun when I noticed little orchid seedling growing on a tree in one of the town's streets. It was Dendrobium crumenatum. About fifty feet away, in the patio of a house, there was an enormous specimen plant of this species and probably it was the source of the seeds. It appears now we have a new invasive orchid species on the island.
