Prem-- How very unusual! It sorta reminds me of an Angraecum and a Masda at the same time.
You said it is fragrant at night? That is also cool. We have a cactus (I know it is not an Orchid, but I love all unusual plants ) here in the greenhouse that blooms only at night. The blooms are about as big as my hand and open just at dark and close with the morning sun.
How long do the blooms last on this Aeranthes? The flower looks thick; I would guess it last a long time once it opens.
Thanks for posting this bloom. I don't think I have ever seen one like it before. (Another for my list!)
