About
Cnidoscolus texanus, commonly known as Texas bullnettle (also Texas bull nettle and Texas bull-nettle), tread-softly, mala mujer, and finger rot, is a perennial herb covered with stinging hairs. The main stem, branches, leaves, and seed pods are all covered with hispid or glass-like bristly hairs that release an allergenic toxin upon contact. Contact with the plant results in intense pain: stinging, burning, and itching lasting for hours. It is native to the U.S. states of Texas, Arkansas, Kansas, Louisiana, and Oklahoma and also native to the northeastern state of Tamaulipas, Mexico. It is a herbaceous flowering plant that grows between 30–80 cm (11.8–31.5 in) tall and as much as 1 m (3.3 ft) across.
