Tragia urticifolia, commonly called nettleleaf noseburn,[1] is a species of flowering plant in the spurge family (Euphorbiaceae). It is native eastern to North America, where it is found in the southeastern United States.[2][3] Its typical natural habitat is in rocky or sandy dry woodlands, over calcareous or mafic substrates.[3][4]
Tragia urticifolia is an erect perennial herb or subshrub. Its leaves are triangular-lanceolate, truncate to cordate at the base, with an acute to acuminate tip. Its petioles are around 3-15 mm. It produces small yellow flowers from late spring through summer. Tragia urticifolia can be distinguished from the similar looking Tragia betonicifolia by its longer pedicels on staminate flowers (1.5-2 mm), which are more evenly distributed in the raceme.[3]
This species is notable for having stinging hairs that are very painful upon contact with skin.[5]
