Ive met both of them. What can tell you something is aloifolia for certain is its fruit: its ...purple. I had the unfortunate experience of touching some...its not pleasant to touch...purple..
Also, aloifololia has serrated edges. If you piece those 2 together....
Ive not seen something this high up, despite the abundance of gloriosa, flaccida and fillamentosa. Only near the mediterraneaen cost, in warmer dry areas(7b and above).
