bus inter se subaequalibus, 0,7 cm longis; petala sub-2-seriata, linearia 
acuta aurea rubro-vittata ad 0,9 cm longa, 0,18 cm lata; stamina omnia 
fertilia convergentia, 0,5 em longa; ovarium supra semi-globosum, stylis 
11—12 erecto-patentibus, 0,3 em longis; capsula semi-globosa, 1,2 cm 
diam, — Cape Colony, Willowmore, fl. July, E. Pillans (in herb. N. S. 
Pillans, 1266!). — A very distinct species which may readily be known 
by its flat leaves. It seems best placed in the $ Aloidea, from which, 
however, it differs in having 3-nate flowers and 11—12 styles. The 
flowers closely resemble those of M. vittatum N. E. Br. The leaves are 
a greyish brown with tinges of red (90, in Prang's System of Colour is 
a very good match), and finally spread out, forming a rosette.
