|discussion=<p><i>Astraea lobata</i> is a weedy annual widely distributed throughout the New World tropics and subtropics. It is not clear where in this area the species is native and where it has been introduced. The records from the flora area, which are restricted to Manatee, Miami-Dade, and Pinellas counties, probably represent introductions rather than natural occurrences.</p><!--
--><p><i>Astraea lobata</i> is highly variable and it has been divided into numerous subspecies or distinct species. It is treated here as a single species; it is not clear if any of the subspecies warrant recognition. The Florida material agrees well with the type material of the species from Veracruz, Mexico.</p>
