Taxonomic notes


A description of Hypoxis juncea is provided in The Flora of North America. Hypoxis juncea is a perennial herbaceous species.




It is a longleaf pine flatwoods/ sandhill species.[1] However, it can also occur in disturbed areas, including grassy roadsides. [2] It prefers open, moist conditions in sandy or loamy soils. [2] Associated species include Pinus palutris, Pinus elliottii, and Quercus laevis. [2]


H. juncea has been observed flowering from February through June and in September with peak inflorescence in March.[3][2] Fruiting was observed in March through June. [2] Kevin Robertson has observed this species flower within three months of burning. KMR

Fire ecology

This species has been found in habitat that is maintained by frequent fire. [2] H. juncea appeared to have benefited from high fire frequencies in a study in 2003.[1] Observed H. juncea respouting at least 10 days after a fire that occurred in June of 1993.[4]


The following Hymenoptera families and species were observed visiting flowers of Hypoxis juncea at Archbold Biological Station: [5]

Halictidae: Augochlorella gratiosa, Lasioglossum nymphalis

Use by animals

Deyrup observed this bee, Dialictus nymnphalis, on H. juncea.[6] “…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.[7]
