I am trying to identify the attached orchid. Found hanging in a tree in Zone 10. Cluster about 6" in diameter. Waxy double star flowers. stringy vine with leaves round to long.
Sorry, its not an orchid. Nice plant, not an orchid. All orchids have 3 petals and 3 sepals. The petals sit forward of the sepals. They are not arranged evenly as in your specimen. In almost every case one of the petals, usually the lower own, will have a different shape. That petal is known as the runway petal and is used by the plant to attract insects. Behind those three petals will be the three sepals. Quite often the top sepal will be dominant and is known as the dorsal sepal. But this process can reversed with the runway at the top and the dorsal (no longer a dorsal) at the bottom. Orchids may produce individual flowers but most often they produce an inflorescence or a group of flowers which grow along a spike, not from a branch as in your photo. I have little expertise in the group you are asking about but my guess would be a Hoya. There are a number of Hoya experts on this board and hopefully one will soon either tell you I'm wrong or tell you what it actually may be.
