This looks like a hybrid of arborescens (perhaps with ferox) and not the species ferox. The leaves are narrow, the plant appears to be branching heavily, and the inflorescence is roughly conical instead of being more like a cylinder. For comparison here are the flowers on arborescens and ferox.
I would like to propose moving this image and the other one of the same plant to the genus entry for Aloe.
Please let me know what you think. Maybe you have some insider info that would explain the differences I have observed.
