2. Poison Ivy Tree:
Poison ivy (Toxicodendron radicans) is a perennial climbing vine in the northeastern, southeastern, and Midwestern United States.
The sap can cause a skin rash, and the tree has thorns along its stem that are sharp enough to pierce skin or clothing. It is also toxic if ingested.
3. Manchineel Tree:
The manchineel tree (Hippomane Mancinellifolia) originates from Central America and is now found throughout much of North America and parts of South America but primarily grows along the Caribbean and Mexico.
The tree is considered a “locally invasive” species because it can destroy ecosystems if uncontrolled. In addition, the manchineel’s fruit, leaves, bark, and sap can cause skin irritation and even death if ingested.
