Recently it was placed in Camphorosmioideae (A. J. Scott 1978), mostly due to the presence of the broad wing formed by the encircling perianth segments. However, the development of the wing in Cycloloma seems to be very different from the mode of development of a similar wing (or other appendages) in Kochia, Bassia, and other genera of Camphorosmioideae. In my opinion, Cycloloma is more closely related to Chenopodium in the broad sense; the problem of its proper placement requires additional study.</p> |tables= |references= }}<!-- --><!-- -->{{#Taxon: name=Cycloloma |author=Sergei L.
