Abstract

HINOJOSA-ESPINOSA, Oscar  and  VILLASENOR, José Luis. Arctotheca prostrata (Asteraceae: Arctotideae), a South African species now present in Mexico. Bot. sci [online]. 2015, vol.93, n.4, pp.877-880. ISSN 2007-4476.  https://doi.org/10.17129/botsci.223.

Arctotheca prostrata is a South African species that has been introduced in other parts of the world, such as California and Australia. Here we report the presence of A. prostrata for the first time in Mexico. To date we have detected the species in nine sites south of Mexico City. The species shows weedy tendencies at each site. It is possible that A. prostrata arrived to Mexico through horticulture and later escaped from cultivation. This species needs to be included in the list of Mexican prohibited weeds, thus permitting the implementation of preventive strategies to avoid its spreading in the country.

Keywords : Arctotidinae; escaped from cultivation; introduced weeds; South African weeds.
