This is very new to me!
It probably doesn't really occur in cultivation because most people use potted culture to grow Phals rather than mount them, and most people have not grown a single individual Phal for long enough of a period of time to see it happen.
I'll bet if more people mounted their Phals, they'd keiki like crazy along the roots.
It suddenly makes a lot of sense why in the past in places such as the Philippines that Phal stuartiana was considered a weed plant.
For a plant that grows as slow as most Phals do, it makes no sense to call them weeds. But when they freely keiki from the stems and the roots as well as occasionally keiki from the inflorescence, and add on to the fact that they produce thousands of seeds per pod, then of course they'd pop up everywhere!
Phal roots have meristematic tissue all along the roots in varying places. That's why if a root gets partially damaged, it's not a big deal, they can grow back from that undifferentiated root meristem.
This is also an exemplary reason to never, ever, trim the roots on your Phals!
Throwing out keikis along the roots may not be solely a trait of Phal stuartiana or Phal schilleriana. It could be that all Phals and Doritis can do this to some degree or another.
This is probably one of the reasons why meristem cloning of Phalaenopsis and Doritis roots is possible, idk.
