摘要
the state of conservation of the representatives of the genera froleichia moench and froelichiella r.e. fries (amaranthaceae) in brazil is discussed based in the criteria of international union for conservation of nature and natural resourses (iucn). most of the species can be considered as vulnerable, but may also present more serious problems on a regional basis, while some species should be considered as probably extint (ex), criticaly endangered (cr) or endangered (pe) at least in large part of their original distribution range.
