The minute stature of Anthurium nemoricola, combined 
with the unusual shape, venation and texture of the leaves, 
serve to set this concept apart from other Amazonian 
species of the genus. It is highly adapted to the xero- 
phytic conditions which obtain, in spite of ample rainfall, 
because of high acidity. The habitat, as indicated by the 
specific epithet, is a light savanna-forest of small treelets 
and abundant light.
