This is meant to be a reference for accepted names of intergeneric hybrids among Aloes and their close relatives. After a major revision a few years ago, these genera were rearranged, thus the proliferation of new names.

Please speak up if you have corrections or names to add to the list. The original source was Alsterworthia International 14(2), 2014. I will be looking at how our database names for these plants and revising those names where necessary.

Special thanks to @BlueOddish for bringing this to my attention.
