The two new trees belong to an extraordinary genus (Pisonia), containing rare plants mainly known for the ability to tangle birds with their sticky fruits, which inspired the common name “bird-catcher”.  The trees are from the four-o’clock family (Nyctaginaceae) and only found in Puerto Rico.   Pensoft Blog interviewed lead author Caraballo-Ortiz. He remarked that “Birds are the main dispersal agents for Pisonia trees, carrying the sticky fruits glued to their feathers to distant islands. However, sometimes these fruits can trap too tightly and even kills birds, as seen in documentaries. So far, we do not know of cases where birds have been trapped by the sticky fruits of the new species, but future studies will explore this possibility.”  The species have been named for two extraordinary women who spent decades on large educational projects aimed to divulge botanical knowledge in Puerto Rico.
