  Amaranthaceae - Wikipedia, the free encyclopedia
The main differences between Amaranthaceae and Chenopodiaceae are membraneous petals and stamens often united in a ring structure.
Most of these species occur in tropical Africa and North America.

 Caryophyllales
Rhabdodendraceae are evergreen trees that may be recognised by their fringed-peltate hairs, their rather large, entire and exstipulate leaves, flowers with stamens that have short filaments and long anthers, and a single carpel with a basal style.
Amaranthaceae (inc. Chenopodiaceae) are palynologically fairly homogeneous (Nowicke 1975; Skvarla and Nowicke 1976), having similarly thickened tecta, apertures with reduced pointed flecks of exine underlain by lamellar plates, and a thickened endexine.
Amaranthaceae sensu stricto have cuticle waxes lacking platelets; scarious bracts and perianth, and the filaments are often connate; n = (6-)8-9(-13, etc).

 Amaranthaceae sensu lato
Because the name 'Amaranthaceae' was published earlier than the name 'Chenopodiaceae', it is the correct name to use when the two families are combined.
For instance, the Chenopodiaceae had stamens that were usually distinct whereas those in the Amaranthaceae varied from slightly to completely connate; the Chenopodiaceae had greenish, membranous or fleshy tepals whereas the Amaranthaceae has white, pink, or red dry, papery tepals.
The Amaranthaceae are herbs or shrubs (often low shrubs in our port of the world), not trees; some species are succulent throughout, others simply have succulent leaves, others are not succulent at all.

 Amaranthaceae
Discussion: Amaranthaceae are here broadly defined and include the Chenopodiaceae, which' usually have been maintained as a separate family because of their usually distinct (vs. slightly to completely connate) stamens and greenish and membranous to fleshy (vs. white, white with green stripes, to pink or red, and dry/papery) tepals.
The usually small, densely clustered flowers of Amaranthaceae are pollinated by wind or by various insects; selfing as well as outcrossing may occur.
The small, dry fruits or seeds, which are typically associated with the accrescent and sometimes hairy perianth, usually are dispersed by wind or water.
