Somebody grows Luisia? This is my new plant. So, yesterday I visited a friend and saw a clump of Dendrobium crumenatum mounted to a mango tree. Observing the plant, I saw some other plant among the dendronium. With terete leaves. I asked her what kind of flower it has. But she said she never paid attention to those plants. So, I asked her if I could have some to take home. Generously, she gave me five plants. After searching the internet, I think this is a kind of Luisia. Perhaps Luisia javanica?
