    • n vernonia A genus of composite plants, type of the tribe Vernoniaceæ and Subtribe Euvernonieæ. It is characterized by a polymorphous inflorescence, usually with a naked receptacle, ten-ribbed achenes, and a pappus of two or three series, the inner slender, copious, and elongated, the outer much shorter, often more chaffy, sometimes absent. There are about 500 species. They are chiefly tropical, abundant in America, numerous in Africa, and frequent in Asia. A few occur beyond the tropics, in North and South America and South Africa. One Asiatic species, V. cinerea, is very common also in Australia, and is naturalized in the West Indies. None occurs in Europe. They are shrubs or herbs, usually with straight, crisped, woolly or tangled hairs, rarely stellate or scurfy. The leaves are alternate, entire or toothed, feather-veined, petioled or sessile, but not decurrent; in V. oppositifolia and V. eupatorifolia of Brazil they are opposite. The fruit consists of smooth or hirsute achenes, commonly glandular between the ribs. The flowers are purple, red. bluish, or rarely white; they form terminal flowerheads, which are usually cymose and panicled, or corymbose, sometimes solitary or glomerate. The large section Lepidoploa includes over 200 American species, chiefly with many-flowered subspherical corymbed heads; to this belong the 10 or more species of the United States, which are known as ironweed, perhaps from the hardness of their stems, and are peculiar in their usually crimson flowers, brown or rusty-colored pappus, and resinous-dotted achenes. They are polymorphous, and disposed to hybridize. V. Noveboracensis, also known as flattop, extends north to New England; V. altissima, to Pennsylvania; and V. fasciculata, to Ohio and the Dakotas; the others are chiefly southwestern. V. arborescens is the fleabane of Jamaica. A decoction of V. cinerea is used in India as a febrifuge. The small black seeds of V. anthelmintica, a common annual of India, yield by pressure a solid green oil known as khatzum- or kinka-oil, esteemed of value iu the arts.
