Afr. vol. vii. p. 459.—A. BERGER. : 
Aloe rubrolutea appears to. have a wide range in the 
Kalahari desert and in German South-west Africa where it 
has been collected by several travellers. It is said to be 
plentiful in the neighbourhood of the Etasa Lake and on 
the mountains near Klein Windhoek. Dr. Schinz gives 
the stems as from 34-5 ft. in height, but Mr. Dinter reports 
them as reaching 8 ft., and judging from photographs even 
taller individuals are not infrequent; indeed in the wild 
state it appears to come nearest in size to A. dichotoma, It 
has been repeatedly introduced to Europe by Dinter, and 
seems to have also been collected by Dr. Baum during his 
Kunene-Zambesi expedition. The plant from which the figure 
now given was made was sent alive as a young specimen 
by Dinter from Windhoek, in 1904, to the late Sir T. 
JuxLy, 1909.
