***Geraea viscida*** is a species of flowering plant in the family [Asteraceae](/source/Asteraceae) known by the common name **sticky geraea**, or **sticky desertsunflower**. It is native to southern [California](/source/California), mainly the [chaparral](/source/Chaparral) hills of eastern [San Diego County](/source/San_Diego_County,_California), and nearby [Baja California](/source/Baja_California).[1]

*Geraea viscida* is a bristly, [glandular](/source/Gland_(botany)) perennial [geophyte](/source/Geophyte) producing scrubby stems reaching anywhere from 30 centimeters (12 inches) to nearly a meter (39 inches) in height. The slightly hairy leaves are several centimeters long and generally oval-shaped, sometimes with small teeth and basal lobes. The [inflorescence](/source/Inflorescence) holds one or more [flower heads](/source/Head_(botany)) which are knobby clusters of yellow disc florets but no ray florets. The [phyllaries](/source/Bract) surrounding the flower head are particularly sticky. The fruit is an [achene](/source/Achene) up to a centimeter (0.4 inches) long, not including its [pappus](/source/Pappus_(flower_structure)) hairs.[2]
