as A. supralaevis, B Hanburii, from European cultivated 
specimens, cannot be distinguished from that figured by Mr. 
Medley Wood as A. Marlothii, and Mr. Medley Wood’s Natal 
plant is identical with the Transvaal one described by Mr. 
Berger. As Wood remarks, A. Marlothii had, until Berger 
defined it, been confused in South Africa with A. ferox, 
Mill., figured at t. 1975 of this work, and it is possible that 
there, as in Europe, it may have been confounded with 
species other than A. ferox, which have themselves been 
misunderstood. This confusion cannot be unravelled here ; 
Mr. Berger’s species is, however, a very distinct one which, 
while approaching A. feror as regards the colour of its 
flowers, is in other respects more nearly allied to A. Galpini, 
Baker, in which the flowers are red.

and uniformly spinescent throughout on the back, but 
sometimes quite unarmed above and only sparingly spines- 
cent on the back; thorns brown-tipped. Peduneles erect,

long; pedicels 3-4 in. long, stout, recurved, green. 
Perianth 14 in. long, subcylindric, slightly dilated at the 
top, segments rounded and hardly spreading at the tip,

filaments dark violet, the enclosed portion pale yellow; 
Style exserted, pale yellow with a brown tip.
