Bidens heterosperma is an annual herb with narrow, yellow, discoid heads in our area, but apparently elsewhere there can be up to 3 ray florets present. The leaves are deeply divided with narrow lobes. The few, short bractlets that occasioanlly can be found subtending the heads are more frequently absent. B. heterosperma thus far in the Gila has only been found growing on soil in cracks in rock and on soil over bedrock at middle elevation in ponderosa forest.
