The Corispermoideae are a subfamily of the Amaranthaceae, formerly in family Chenopodiaceae.
The species of the subfamily Corispermoideae are all annual plants. Leaves are mostly alternate, sessile or petiole-like attenuate, laminate, scleromorphic. Typical are branched (dendritic) trichomes (except in Anthochlamys) on young plant parts.
The flowers are arranged in simple, compact (sometimes globular) partial inflorescences, or in spikes. Bracteoles are missing. The perianth consists of 1-5 white, membranaceous tepals (missing in some Corispermum species) without vascular bundles, not persistent. The pollen grains of Agriophyllum and Corispermum are of the "Chenopodium type", of Anthochlamys of the "Anthochlamys type".
The fruits possess supporting tissue consisting of macrosclereids. The seeds have a vertical embryo and copious perisperm.[1]
Distribution
The subfamily Corispermoideae is distributed in Asia, Europe and North America.[2]
Photosynthesis pathway
All species studied show non-Kranz corispermoid leaf anatomy and C3 photosynthesis.[2]
