Urereae
Quick Summary
The Urereae, also known as Urticeae, are a tribe within the nettle family (Urticaceae). They are most recognizable due to their stinging hairs, which can cause temporary irritation or, in some cases, prolonged pain and numbness. These hairs have a bulbous base and a hollow tip that penetrates the skin, injecting a fluid containing compounds like histamine and acetylcholine.1
While the stinging nature of Urereae is prominent, other plants in the Urticineae suborder can also cause skin irritation. A common characteristic of the nettle family and the mulberry family (Moraceae) is the presence of cystoliths, which are calcium carbonate deposits within plant cells that may offer protection against herbivores.1
