Basal keikis or canes on Dendrobium nobile?

[CJ Green]

Hi folks,

My Dendrobium has three new growths, and two of them are growing from the sides of older canes, near the bottom. Can anyone tell me if these are keikis? I'm not sure what I should do about them--if they grow roots, I guess I can just let them stay as is? I'm just afraid they won't be very stable. This plant's growth patterns mystify me!

Edited to add pictures of this plant in bloom. The cane is really awkward and bent, but it sure put on a show!
