Patinoa ichthyotoxica differs strikingly from the other 
three species in its fruit which is very large and nearly 
perfectly globose. The fruit of Patinoa paraensis and P. 
Almirajo are, respectively, ovoid and elliptic-ovoid. In 
shape, the fruit of this new species resembles that of 
Patinoa sphaerocarpa, but it is much larger and differs 
in several internal characters. There are also conspicuous 
differences in shape and indument of floral parts between 
Patinoa ichthyotoxica and the other three species.
