Description
A description of Hypoxis juncea is provided in The Flora of North America. Hypoxis juncea is a perennial herbaceous species.
Distribution
This species is distributed from southeastern North Carolina south to southern Florida and west to southern Alabama[1] with disjunct populations in western Cuba.[2]
Ecology
Habitat
It is a longleaf pine flatwoods/ sandhill species.[3] Generally, Hypoxis juncea is found in wet pine savanna communities.[1] However, it can also occur in disturbed areas, including grassy roadsides. It prefers open, moist conditions in sandy or loamy soils.[4] It can also be found in flatwoods and bogs occasionally.[5] Within the Atlantic and Gulf Coastal Plain, the USDA Natural Resources Conservation Service lists this species as a facultative wetland species that most often occurs in wetland habitats, but can also occasionally be found in non-wetland habitats.[6]
Associated species include Pinus palutris, Pinus elliottii, and Quercus laevis.[4]
Phenology
H. juncea generally flowers from April through May and can be later especially in response to fire disturbance.[1] It has been observed flowering from February through June and in September with peak inflorescence in March.[7][4] Fruiting was observed in March through June.[4] It has been observed to flower within a few weeks of burning in native pine savannas.[8]
Seed bank and germination
Seeds of H. juncea were found in the seed bank after a fire disturbance in a flatwoods habitat in Hardee County, Florida.[9]
Fire ecology
This species has been found in habitats that are maintained by frequent fire.[4] H. juncea appeared to have benefited from high fire frequencies in a study in 2003.[3] Observed H. juncea resprouting at least 10 days after a fire that occurred in June of 1993.[10]
Pollination
Hypoxis juncea has been observed at the Archbold Biological Station to host sweat bees from the Halictidae family such as Augochlorella gratiosa, and Lasioglossum nymphalis.[11] Deyrup observed Dialictus nymnphalis, on H. juncea.[12]
Herbivory and toxicology
H. juncea is one of the most important plants for quail, which occurred (resprouted) in the ranking only the first 1 or 2 months after fire."[13] Overall, though, it is considered to be of poor forage value.[14]
Conservation, cultivation, and restoration
Due to Hypoxis juncea being considered critically imperiled in North Carolina, it is listed as G4 on the global scale.[5]
