Resumen:
To study synanthropic plants (weeds), they need to be separated from
non-weeds, a difficult task due to the existing gradient in nature. A
representative family of the Mexican flora (Asteraceae) and a state very
rich in species (Michoacan) are used as a model for this task and
additional analyses. A total of 357 weeds are listed based on a critical
review of specimens and bibliographic information, as well as defined
criteria. In addition, tribes, growth forms, and geographic similarities
with other states are examined for endemic, more widespread native, and
introduced weeds. The main difficulty in differentiating weeds from
non-weeds was the lack of accurate habitat information on herbarium
labels. Most species grew in both disturbed and natural environments.
Nearly half were endemic to the country, with only 4% introduced. The
major Asteraceae tribes had relatively similar proportions of weeds, but
exotics were concentrated in the tribe Cichorieae. Floristic
similarities were mainly towards south-central Mexico. Most species were
herbs and less than half annuals. We contribute to the delimitation and
understanding of synanthropic species.
