Additional comments

Similar moprhologically to Crinum. Most Hymenocallis species are amphibiousamphibious:
(adj) of a plant able to live on land or in water
and tolerate extended periods of submersion. Because this genus contains various alkaloids, it is not recommended that plant parts be eaten or even touched if allergic. It is difficult to identify species from herbarium specimens; use fresh material whenever possible.
