''Cnidoscolus texanus'', commonly known as Texas bullnettle, treadsoftly, and mala mujer, is a perennial herb covered with stinging hairs, native to the U.S. states of Texas, Arkansas, Kansas, Louisiana, and Oklahoma. It is also native to the northern Mexican state Tamaulipas. It is an herbaceous flowering plant that grows between tall and as much as across.〔Johnston MC, and BH Warnock. 1963. The species of ''Cnidoscolus'' and ''Jatropha'' (Euphorbiaceae) in far Western Texas. ''The Southwestern Naturalist'', 8(3): 121-126.〕 ''Cnidoscolus texanus'' has white flowers and blooms all throughout the year. The main stem, branches, and leaves are all covered with hispid or glass-like bristly hairs that release an allergenic toxin upon contact. It is a drought-tolerant plant, therefore making it a superb choice for xeriscaping. This plant is also attractive to bees and butterflies, among other insects, as well as birds. Exposure to the plant by contact results in intense pain, burning, and itching and if not treated promptly can cause problems ranging from skin infection to allergic reaction. ==Description== It is a perennial plant with erect, branching stems growing from thick root stock. It has milky latex and stiff prickly glandular-based hairs. The leaves are simple and are alternately arranged on the stem, and each leaf is deeply cut with 3 to 5 lobes. The flowers are in a few flowered terminal cymose inflorescence. Flowers have five sepals and lack petals, the sepals are lobed, white, fragrant, and covered with hispid hairs. Each flower has 10 connate stamens. The fruits are prickly 3-seeded capsules and the seeds are consumed by Rio Grande wild turkeys and mourning doves. It was first described by Johannes Müller Argoviensis in 1865 as ''Jatropha texana''.〔 It was then moved to the genus ''Cnidoscolus'' in 1903 by John Kunkel Small. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cnidoscolus texanus」の詳細全文を読む スポンサード リンク
