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]
Ecology
Habitat
It is a longleaf pine flatwoods/ sandhill species.[2] 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.[3] It can also be found in flatwoods and bogs occasionally.[4] 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.[5]
Associated species include Pinus palutris, Pinus elliottii, and Quercus laevis. [3]
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.[6][3] Fruiting was observed in March through June. [3] Kevin Robertson has observed this species flower within three months of burning. KMR
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.[7]
Fire ecology
This species has been found in habitat that is maintained by frequent fire. [3] H. juncea appeared to have benefited from high fire frequencies in a study in 2003.[2] Observed H. juncea respouting at least 10 days after a fire that occurred in June of 1993.[8]
Pollination
The following Hymenoptera families and species were observed visiting flowers of Hypoxis juncea at Archbold Biological Station: [9]
Halictidae: Augochlorella gratiosa, Lasioglossum nymphalis
Deyrup observed this bee, Dialictus nymnphalis, on H. juncea.[10]
Use by animals
“…Hypoxis is one of the most important plants for quail, which occurred (resprouted) in the ranking only the first 1 or 2 months after fire."[11] Overall, though, it is considered to be of poor forage value.[12]
Conservation and management
Due to Hypoxis juncea being considered critically imperiled in North Carolina, it is listed as G4 on the global scale.[4]
