Flowers bisexual, usually 2 or 3 per axillary glomerule. Perianth green, densely pilose; winglike appendages rhombic to fan-shaped, membranous, brownish yellow veined, apical margin erose. Stigmas 2, exserted, filiform. Style very short, ca. 1/4 as long as stigma. Utricle ovoid; pericarp thinly membranous.

Plants with perianth segments rhombic, narrowed at base, and not erose at margin correspond to Kochia stellaris s.str., whereas plants with perianth segments orbicular, erose at margin, have been segregated as K. iranica. The difference between these two entities is problematic.
