| description | Senecio inaequidens DC., a weed of South African origin, is reported from 10 localities of central Mexico. In most places the populations are small and apparently of recent arrival. However, in the vicinity of the town of Amealco, situated in the southern extreme of the state of Querétaro, the species is extremely abundant in ruderal environments and apparently has existed there for 50 or more years. his paper summarizes information concerning uncertainty of the identification of the species, particularly in connection with the use of the name Senecio madagascariensis Poir. It includes also some outstanding aspects of its geographical distribution and of the history of its invasion in central and southern Europe, Australia and Argentina, where in recent decades the plant has become a severely noxious weed, especially in cattle raising areas, and also a dangerous competitor of native plants in some natural environments. description and illustrations of the species are included, as well as a discussion of its ecological and agronomic relevance. |

Senecio inaequidens DC. se registra como maleza invasora de origen sudafricano, presente en al menos una decena de localidades del centro de México. En su mayoría se trata de poblaciones pequeñas de reciente aparición, aunque éste no es el caso de los alrededores de la ciudad de Amealco, ubicada en el sur del estado de Querétaro, donde la planta es sumamente abundante en todo el medio ruderal y al parecer está allí desde hace 50 o más años. Este artículo resume la información sobre la incertidumbre en la identificación de la especie, en particular en conexión con el uso del nombre Senecio madagascariensis Poir. Incluye asimismo lo más sobresaliente del conocimiento actual acerca de su distribución geográfica, así como de la historia de su proceso invasivo en Europa central y meridional, en Australia y en Argentina, áreas en que la planta se ha convertido en las últimas décadas en maleza altamente perjudicial, sobre todo para los aprovechamientos ganaderos y también como peligroso competidor de especies nativas en algunos ambientes naturales. Se incluye la descripción e ilustraciones de Senecio inaequidens, así como una discusión de su relevancia ecológica y agronómica.
