The Polycnemoideae are a small subfamily of plants in the family Amaranthaceae sensu lato. The few relictual species are distributed in Eurasia and North Africa, North America, and Australia.
== Description == The subfamily Polycnemoideae comprises small herbs; some species are weakly lignified and grow shrublike. The subfamily is distinguishable from all other members of Amaranthaceae by normal secondary growth. The alternate or opposite leaves are often linear or subulate. The stomata of the leaves are arranged in parallel to the midveins.
