Does it have a new growth starting from one of the canes? Does it have a name?

Might not be getting the correct amount of shade for the latitude.

What can it be? Stress but be aware that a healthy plant should have a number of canes with leaves counting back from the front of the plant (3 to 5) and then a few canes with no leaves but are still green and thus provide support to the growing parts.

How do you know it is a Phal type Den?

It just finished bloom last month. Maybe I named it wrong. Not quite sure if it is Den phal.

Did the flowers have a similar shape to those in the link?

Round filled in shape Dendrobium
