Within this group, there are edible plants, such as spinach, chard or beetroot. The most typical representatives in this group from an allergologic point of view are:

Lamb's quarter (Chenopodium Album) A plant that flowers between May and December, mainly in barren lands, ditches, near stables, gardens and areas wher vegetables are grown.

Russian tistle (Salsola Kali) A plant that flowers in July and August, mainly in plowed lands, fallow lands, and beaches.

The pollen of Chenopodiaceae and Amarantaceae are indistinguishable with an optical microscope. They have a small pollen (10-28 µm of diameter), with a lot of pores that give it a "golf ball" appearance.
