Bidens L. (Coreopsideae, Asteraceae), a new generic record for Abu Dhabi, United Arab Emirates

We report a collection of Bidens pilosa L. from an urban habitat in Abu Dhabi. This represents a new generic record of Bidens L. for the emirate. The species has most likely been accidentally introduced and has the potential to affect the native flora because of its fast rate of growth. The new record expands the geographic distribution of the species and highlights the importance of expanding surveys to include urban habitats, which would help track the spread of non-native species within the emirate.
