@Needrain - the keiki is just a baby orchid. When they first emerge, quite small obviously. But as they get bigger, they just look like a small Phal. :-)
Two of my Phals have thrown basal keikis. Sometimes that is an indication of a declining plant. Often not. In my case, both the plants look fine. One of these is on the Phal that has a stem based keiki that is ~ 1 year old. Close to time to remove it. The Repotme site above has a lot of good info.
