The proposal that Aloe ramossisima be reduced to varietal rank under A. dichotoma, based on a low incidence of ramossisima-type branching pattern (less than 100 mm above ground level) in most A. dichotoma populations, is invalid, as the ramossisima-type branching pattern has a different cause in the two taxa. Branching patterns in A. dichotoma populations show a majority of first branchings at between 1.5 m and 2.4 m above ground.
