Gray and Ypsilandra Franchet have been noted repeatedly. They exhibit many similarities in morphology and anatomy (F. Buxbaum 1925, 1927; W. Schulze 1978b; C. Sterling 1980; F. H. Utech 1978b; F. H. Utech and S. Kawano 1981; N. Tanaka 1997, 1997b, 1997c, 1997d, 1997e, 1998), palynology (M. Takahashi and S. Kawano 1989), ecology (S. Kawano and J. Masuda 1980; H. Takahashi 1988), and karyology (F. H. Utech 1980). Based on these similarities, Tanaka merged the five species of Heloniopsis and the three species of Ypsilandra into <i>Helonias</i>. However, molecular evidence indicates that, although the genera are related, they are distinct (S. Fuse and M. N. Tamura 2000). This group has been recognized as a separate tribe, Heloniadeae Fries, within the Melanthiaceae sensu stricto (M. N. Tamura 1998; W. B. Zomlefer 1997b), or placed in a separate family, Heloniadaceae J. Agardh (A. L. Takhtajan 1997).</p><!-- --><p><i>Helonias</i> in eastern North America and the Ypsilandra–Heloniopsis lineage in eastern Asia comprise a paired Arcto-Tertiary element in which Ypsilandra (western China to the Himalayas) and Heloniopis (Taiwan, Korea to Japan) have differentiated from each other in eastern Asia (N. Tanaka 1997e).</p> |tables= |references={{Treatment/Reference |id=sutter1984a |text=Sutter, R. D. 1984. The status of Helonias bullata L. (Liliaceae) in the southern Appalachians.
