Discussion

Hymenocallis liriosme has become a favorite for gardens west of Mobile Bay, Alabama. Its leaves are numerous, liguliform to narrowly lanceolate, highly coriaceous, and shiny green. The numerous, small, highly fragrant flowers with the center of the staminal corona having a prominent, yellowish green eye are characteristics useful in distinguishing this species from H. occidentalis (W. S. Flory 1950) and from H. choctawensis (R. Gooch and G. L. Smith 1994; G. L. Smith and N. C. Coile 1999).

Numerous herbarium specimens of Hymenocallis liriosme were identified by H. P. Traub as H. galvestonensis. However, close examination of Rafinesque’s original publication of Pancratium liriosme leaves no doubt that this earlier name does apply to this taxon and that therefore its epithet has priority.
