Resumo(s)
The Siam weed, Chromolaena odorata (L.) R. M. King & H. Rob. (Asteraceae), is
recognized as one of the world’s worst tropical weeds. It is a perennial herb or
shrub native to the neotropics that has become invasive across the tropical regions
of Africa, Asia and Oceania. The species was introduced in 1937 in Nigeria and
later spread to neighboring countries. Its presence and effects have been documented
in the upland zones of almost all West African countries. Although, until the present
study, the species had not been recorded in Guinea-Bissau, its presence in the
country was very likely. In this work we document, for the first time, the invasion
of Guinea-Bissau by C. odorata, assessing its present distribution and reporting
effects, local uses and common names. Dispersal trends, potential consequences of
its expansion and recommendations for management and control are also presented
