Thismiaceae
Thismiaceae is a family of flowering plants whose status is currently uncertain. The Angiosperm Phylogeny Group classifications noting that some studies have suggested that Thismiaceae, Burmanniaceae and Taccaceae should be separate families, whereas others support their merger.
The family has been recognized by some authors. Others have supported the APG position of merging the family into Burmanniaceae, sometimes as the tribe Thismieae.
For those who keep the family separate, it consists of five genera, three are entirely from Old World, Thismia is from tropical areas of both America and Asia, as well as three temperate species in Illinois, Japan and New Zealand, temperate Australia and Tiputinia is from the Amazon basin.
