Why did this happen?

[Plodde]

Hello! i hope everyone and their 'chids are doing well!

I have a Den. kingianum and it is doing the oddest thing.

I've had it for 2 years. Bought it in flower and haven't been able to get it to bloom since. It grows and grows and grows, new canes, new keikis...
...But this keiki seems to be doing something different.
Here comes the something odd..

The Keiki is growing long roots as you can see from the pictures. but the mother cane that the keiki is attached is starting to grow what appears to be a root out of one of the nodes.
Why does this happen? if i broke off the keiki now there would be a single root growing out of one of the flower nodes on the mother cane...


anyone know why this happens?
