This Aloe is only known from Saudi Arabia and is not at all found in Somalia. Almost like a more green, solitary version of A. vera and with shiny, waxy yellow flowers. First described in 2000 and discovered by Sheila Collenette.

Yemen/ Saudi aloe from higher elevations. Seedlings are heavily spotted, but adults appear spot-free. In my climate (inland southern California) this is a pretty slow growing species. It will be many years I think before I see it flower. Several authors (2010) feel that Aloe hijzensis is the same thing and ranges overlap in Yemen. This aloe is closely related to Aloe vacillans.

Not much experience with the plant, as it is new in my collection. So far it is a pretty addition, though not large - young seedling.
