New plantlet
 

Anyone ever see new plant starting from Mother plant like these pics? Not on a stem, not a kiki.

keiki's can form on the stem, a flower spike or on a cane. So nothing too unusual.
The definition of a keiki is just baby plant. So this is a baby plant on a mother plant = keiki

You mean like this?

Thanks, didn't know it could format on mother plant

Unlike baby plants which develop on flower stems, the ones growing directly from the mother plant are best not removed. Trying to remove a so called basal keiki has a high chance of causing serious damage to one or both plants. So now you'll have a plant with 2 crowns, so in a couple years you can expect spikes from both of them! :)

Many ancestor species of Phal hybrids do this routinely. You wind up with a big clump of rosettes, each of which can flower at the same time. It becomes a very impressive display. I leave them unless I want to give away a piece of the plant.
