    • n urtica A genus of apetalous plants, the nettles, type of the order Urticaceæ and tribe Urticeæ. It is characterized by opposite leaves furnished with stinging hairs and free or united stipules; by the fruit, a straight achene; and by its unisexual flowers, the pistillate with four unequal segments. There are about 30 species, widely scattered over most temperate and subtemperate regions. They are annuals or perennials, in a few species woody at the base. They bear petioled toothed or lobed leaves, usually with from five to seven nerves. The small and inconspicuous greenish twin flowers are borne in small clusters or panicles. For the species in general, see nettle; for U. ferox, see onga-onga. Nearly 400 former species are now classed elsewhere, especially under Laportea, Urera, Pilea, and Bœhmeria. England has 3 species, 2 of which, U. dioica and U. urens, occur occasionally in the United States; 6 others are natives of the United States, 5 in the west and southwest, and 1, U. gracilis, a tall wand-like nettle of fence-rows and springy places, ranging eastward and northward from Colorado to the Atlantic.
