Aloe massawana Reynolds
These originate from Eritrea (Ethiopia), near sea level. The species, massawana, derives from an old locality name, Massawa, in Eritrea.
Identification: Most online sources describe bright red flowers. Leaves occur in rosettes as with other aloes and are green to gray-green, with thorny edges. I was able to find very little information about these.
