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[2] with disjunct populations in western Cuba.[3]

Ecology

Habitat

It is a longleaf pine flatwoods/ sandhill species.[4] Generally, Hypoxis juncea is found in wet pine savanna communities.[2] However, it can also occur in disturbed areas, including grassy roadsides. It prefers open, moist conditions in sandy or loamy soils.[5] It can also be found in flatwoods and bogs occasionally.[6] 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.[7]

Associated species include Pinus palutris, Pinus elliottii, and Quercus laevis.[5]

Phenology

H. juncea generally flowers from April through May and can be later especially in response to fire disturbance.[2] It has been observed flowering from February through June and in September with peak inflorescence in March.[8][5] Fruiting was observed in March through June.[5] It has been observed to flower within a few weeks of burning in native pine savannas.[9]

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.[10]

Fire ecology

This species has been found in habitats that are maintained by frequent fire.[5] H. juncea appeared to have benefited from high fire frequencies in a study in 2003.[4] Observed H. juncea resprouting at least 10 days after a fire that occurred in June of 1993.[11]

Pollination and use by animals

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.[12] Deyrup observed Dialictus nymnphalis, on H. juncea.[13] 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."[14] Overall, though, it is considered to be of poor forage value.[15]

Conservation, cultivation, and restoration

Due to Hypoxis juncea being considered critically imperiled in North Carolina, it is listed as G4 on the global scale.[6]
