The two genera of Haemodoraceae found in North America are very different from each other. Lachnanthes belongs to tribe
Haemodoreae and is morphologically similar to Dilatris P. J. Bergius of South Africa and Haemodorum Smith of Oceania. The relationships
of Lophiola are more obscure
and are discussed more fully in the references cited below and under that genus.Kenneth R. Robertson "Haemodoraceae". in Flora of North America Vol. 26 Page 16, 22, 23, 47, 48, 49, 51, 67. Oxford University Press. Online at EFloras.org.
