of the leaf produced by the same tuber. Specifically A. 
corrugatus is readily distinguished from its nearer allies by 
the spathe being open in front almost to the base, by the 
remarkably corrugated appendix, and -by the purple ovaries 
which are well exposed to view. The delicate shading of 
the rather agreeably coloured spathe and spadix render this 
species more ornamental than some other members of the 
genus, :
