This is very interesting. I have a plant that looks like Suresh's. I'm attaching pictures of the spikes it had when it was given to me, here in Thailand, and a closeup of one of the blossoms that may help identify it. I probably should have photoshopped the picture of the spikes; it's darker than I would wish. It seems very hard to catch the color of this flower. It's a very attractive shade somewhere between yellow and green. I'm sorry that it appears that we don't have the correct name yet, but I'm glad for the chance to learn more about the process of identifying plants.
