"Aggregate bud galls that resemble those of [Asphondylia] monacha on [Solidago] juncea and S. erecta are known from several other goldenrod species, including S. patula, S. odora, and an undetermined Solidago species from Florida, based on material in the National Museum of Natural History, Washington, D.C. (USNM)."

[GF note: Since this publication, Solidago chapmanii, formerly a variety of Solidago odora, has been elevated to species (per Kew's Plants of the World Online). It's not clear whether the record above refers to S. odora in the strict sense, or instead to S. chapmanii. Asphondylia-like galls have been observed on S. chapmanii; there is a separate gallformers page for those galls here, though they may be conspecific with these. However, they are not aggregated, as reported above for those on S. odora.]
