Maxillaria coccinea [Plum] L.O.Williams 1954, a lot of plants growing together in a tree in a Puerto Rico rainforest

Something happened to this tree trunk that seemed to have made it very favorable for the germination and growth of Maxillaria coccinea orchids.  There were dozens of plants growing all together.  None of the plants had bloomed so they are young still.  My suspicion is that a storm broke the top of the tree, making the remaining branches an ideal place for these orchids to colonize.
