Ciclospermum leptophyllum is worthy of note that this plant (in common with others of the genus) is sometimes acrid and injurious when grown in damp soils. It is, doubtless, capable of much improvement by careful cultivation. This plant is not endemic in Australia."

Celery mosaic virus been identified in several weed species in the "Apiaceae" family, including poison hemlock ("Conium maculatum"), mock bishopweed ("Ptilimnium capillaceum") and wild cherry ("Apium leptophyllum"). A 2012 study demonstrated that plants from Solanaceae, Curcurbitacae, Chenopodiaceae, and Amaranthaceae, families, in addition to plants from the Apiaceae family, become infected when mechanically inoculated with purified CeMV. Plants in this study tested positive for the CeMV virus, and displayed similar symptoms to celery, but with reduced severity. There is some confusion in the literature as to whether CeMV can infect hosts in the family "Chenopodiaceae". In 2002, a paper reporting the results of a
