DistributionRestricted to the southern Coastal Plain, mainly in coastal counties from Carteret to Brunswick, but scattered inland to Hoke County (in the Sandhills). The Hoke record is from a Carolina Vegetation Survey plot in 1992 and is not vouchered by a specimen; it was found at the MacRidge Impact Area Buffer Zone.

This is a lower Coastal Plain species, ranging north to southeastern NC, and south to southern FL and west only to southern AL. It is thus known from only five states: NC, SC, GA, FL, and AL.
AbundanceRare, though can be locally numerous (as in Holly Shelter Game Land in Pender County). However, very rare as far inland as Fort Bragg in the Sandhills. This is a Significantly Rare species in the state. The NC NHP database contains roughly 12-13 records, most being extant, though a handful are at sites within the large Holly Shelter Game Land. Thus, their State Rank of S1 may be suitable, though perhaps S1S2 is a better option, as it possibly is being overlooked.
HabitatThis species is strictly limited to savannas, and essentially just the wetter portions.
PhenologyBlooms from April to May (and later after a prescribed burn), and fruits from May into June (and later after a burn).
IdentificationThis is the state's only star-grass (Hypoxis) with filiform (i.e., needle-like) basal leaves. All of the other five species in the state have blade-like or strap-like leaves that are over 2 mm wide as opposed to 1 mm or less wide. Otherwise, it is similar to others, with one or two bright yellow star-shaped flowers on short stems. When working in savannas, especially high quality ones with frequent prescribed burns, be on the lookout for a blooming star-grass, and check the leaves to see if you have this scarce species.
