How to distinguish Dysphania ambrosioides from D. anthelmintica?

In the online version of FNA there is not key of the section.
In one paper I read that D. anthelmintica should be a perennial subshrub but in FNA it is described as an annual.
In some observations and some spcimens in GBIF I see that D. anthelmintica can have very long flowering branches. Another difference should be the maximum length of bracts.
Other more robust differences?
Thanks
