Suaeda pulvinata is an endemic seepweed from Mexico. It lives in the shores of Lake Texcoco and Lake Totolcingo. It lives underwater as an aquatic plant for half of the year and on dry land as a terrestrial plant for the other half due to the changing levels of the lakes that it inhabits.{{cite journal|title=Suaeda pulvinata (Chenopodiaceae), a new species from saline lakes of central Mexico|journal=Willdenowia|volume=43|issue=2|pages=309–314|doi=10.3372/wi.43.43211|year = 2013|last1 = Reyes|first1 = Ernesto Alvarado|last2=Flores-Olvera|first2=Hilda|s2cid=84876004 |doi-access=free}} It is a perennial flat herbaceous herb with prostrate stems. Its leaves and inflorescences are green to reddish in color.{{cite journal|title=Suaeda pulvinata (Chenopodiaceae), a new species from saline lakes of central Mexico|journal=Willdenowia|volume=43|issue=2|pages=309–314|doi=10.3372/wi.43.43211|year = 2013|last1 = Reyes|first1 = Ernesto Alvarado|last2=Flores-Olvera|first2=Hilda|s2cid=84876004 |doi-access=free}}

This species is important for people that live in the states of Puebla and Tlaxcala, as it is an edible vegetable. The dish that is prepared using this species is known as romeritos.{{cite web|url=http://www.botanica.org.br/trabalhos-cientificos/65CNBot/4296-BTE.pdf|accessdate=16 August 2015 |title=Anatomia foliar de dos especies comestibles de romerito}}

It has been found in molecular phylogenetic studies that this taxon is monophyletic.{{cite journal|title=Phylogeny and biogeography of Suaeda subgen. Brezia (Chenopodiaceae/Amaranthaceae) in the Americas| doi=10.1007/s00606-015-1233-y|volume=301|issue = 10|journal=Plant Systematics and Evolution|pages=2351–2375 | last1 = Brandt | first1 = Ronny|year = 2015| s2cid=254060858}} Due to differences in its phylogenetic position in its nuclear ITS tree and its chloroplast rpl32-trnL tree, it is thought this species is the result of hybridization of ancestral species of Suaeda.{{cite journal|title=Phylogeny and biogeography of Suaeda subgen.

The first scientific collector who found this plant was Efraim Hernández Xolocotzi. (Later, it was cited by Guadalupe Ramos in her university degree thesis.) However, he misidentified it for S. nigra. It was in 2013 that Ernesto Alvarado Reyes and Hilda Flores Olvera noticed it was a different species.{{cite journal|title=Suaeda pulvinata (Chenopodiaceae), a new species from saline lakes of central Mexico|journal=Willdenowia|volume=43|issue=2|pages=309–314|doi=10.3372/wi.43.43211|year = 2013|last1 = Reyes|first1 = Ernesto Alvarado|last2=Flores-Olvera|first2=Hilda|s2cid=84876004 |doi-access=free}}
