Genera

Distribution

The majority of species in the family occur along the western edge of the Americas, from Washington to central Chile.[3] However, the type species for Sphaerocarpos, S. michelii, is native to Europe. The weedy species Sphaerocarpos texanus is distributed widely in fields and gardens of North America, western Europe, and Mediterranean Africa. It may have been introduced with soil brought with crops or garden plants imported from the Americas.

Classification

The group was recognized as a tribe by Barthélemy Dumortier in 1874[1] and elevated to family rank in 1891 by Moritz Heeg, under the name "Sphaerocarpeae".[2] Two genera are recognized, with a single species in Geothallus and the remaining species assigned to Sphaerocarpos
