--><p>Traditionally, <i>Cycloloma</i> has been included in Chenopodieae (Chenopodiodeae). 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 <i>Cycloloma</i> seems to be very different from the mode of development of a similar wing (or other appendages) in <i>Kochia</i>, <i>Bassia</i>, and other genera of Camphorosmioideae. In my opinion, <i>Cycloloma</i> is more closely related to <i>Chenopodium</i> in the broad sense; the problem of its proper placement requires additional study.</p>
