Striga gesnerioides ( Willd. ) Vatke, Oesterr. Bot. Z. 25: 11. 1875

Striga, commonly known as witches weed, is a genus of 28 species of parasitic plants that occur naturally in parts of Africa, Asia, and Australia. Witchweeds are characterized by bright-green stems and leaves and small, brightly colored flowers. Furthermore, they are obligate parasites of roots and therefore require a living host for survival. The genus is classified in the family Orobanchaceae, although older classifications place it in the Scrophulariaceae. Although most species of Striga are not pathogens that affect human agriculture, some species have devastating effects upon crops, particularly those planted by subsistence farmers. Crops most commonly affected are corn, sorghum, and sugarcane. Three species cause the most damage: Striga asiatica, S. gesnerioides, and S. hermonthica.
