Several infraspecific taxa have been recognized but the current classification should be regarded as tentative and further studies based on molecular data are needed.
In the Hawaiian Islands the subfamily Amaranthoideae has differentiated, with one genus, Nototrichium, endemic with three species.
The higher level of endemism in Hawaii as compared with that in the Galápagos stems from the combined effects of the more isolated geographical position, the more varied ecological conditions, and the greater geological age of the Hawaiian chain.
