Regularity: Regularly occurring
Global Range: Santa Rosa, Florida; Liberty County, Florida. Clewell (1985) does not recognize this species but states that it occurs in a swamp in Walton County.

Comments: Within the narrow ecotone between dome swamps and mesic/wet flatwoods or within the ecotone between dome swamps and wet prairies. (Based on Kral 1983.)
Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: 21 - 80
Life History and Behavior
National NatureServe Conservation Status
Rounded National Status Rank: N2 - Imperiled
NatureServe Conservation Status
Rounded Global Status Rank: G2 - Imperiled
Reasons: A Florida endemic with a limited distribution due to specialized habitat requirements. The Florida Natural Areas Inventory's database currently contains 25 occurrence records, scattered in the southcentral portion of the Florida panhandle. Habitat destruction from silvicultural activities, fire suppression, and over-collection threaten this species.
Global Short Term Trend: Decline of 10-30%
Comments: Vulnerable to collection, development, silviculture.
Comments: Collecting, silviculture, development, wetland drainage
Biological Research Needs: Need to determine the validity of this species. Clewell (1985) and Godfrey and Wooten (1979) do not recognize this species. Also need more information on reproductive biology and on associated species.
Hymenocallis henryae was designated “H. viridiflora” by J. K. Small (1933). This name is listed as number 10 in Small’s key, but as a result of a clerical error (C. V. Morton 1935), species number 10 was described by Small under the name H. rotatum Le Conte. Even if Small had applied the name H. viridiflora to the description, as he evidently had intended, that name still would be invalid, since it would have been a later homonym of H. viridiflora (Ruiz & Pavón) R. W. Wallace from Peru.
Names and Taxonomy
Comments: Its distinctiveness as a good species was established by Gerald Smith, a Hymenocallis expert; also recognized as a good species by Kartesz (1999 Floristic Synthesis). Clewell (1985) and Godfrey and Wooten (1979) do not recognize this species. Kartesz (letter to Larry Morse, 25Nov99) notes that "this genus is particularly messy ... H. henryae perhaps should be maintained, at least for the time being."
