Anthurium macrocephalum belongs to Engler’s section 
Digitinervium and seems to be closely related to A.

which, while shorter, are wider, giving them a truly ovate 
shape; by having a much longer petiole; by having a 
much thicker spadix which is green, not rose-colored; 
and by having a much longer and wider spathe. 4nthur- 
tum pangoanum is described as being ** 
both surfaces of the leaf, but in A. macrocephalum the
