So I went shopping to get pots for some orchids and came home with more orchids (as well)!
Here are the other two ...

Dendrobium Karen
but this one is a Miltoniopsis Maui Charm (probably a trade name).
It's a large plant with 5 spikes in total. 1 spike fully open, 2 large spikes of buds and 2 small spikes nestled in the leaves. The pbulbs are also huge.
My previous attempt at growing a Miltoniopsis was not very successful (although it's still alive), but I put that down mostly to the plant having bad roots to begin with. The roots look a lot better on this one as far as I can see and it's also a lot bigger so I'm hoping it's going to do better.
Here is the whole plant and one of the larger spikes.
