Distribution | Mountains; with a gap between Yancey and Clay counties.
A circumboreal species, with ssp. glauca ranging south to NC, KY, IL, and AZ. | |
Abundance | Very rare, with apparently just a single collection site in each county. Thankfully, the Clay County site (Buck Creek barrens) is in excellent condition. This is a State Threatened species. | |
Habitat | Rock outcrops or barrens over mafic or limey substrate -- very rare habitat conditions in NC. |
Phenology | Flowering and fruiting June-July. | |
Identification | Stems grow 2-4 feet tall from a tuft of slender and rather short, ascending to erect leaves. The inflorescence is terminal, open, with branches alternate, opposite, or whorled; it is conspicuously very pale to straw colored, in contrast to the green color of the stem and leaves. The spikelets have only 2 florets, as opposed to all of our Poa, Festuca, and Schedonorus taxa. | |
Taxonomic Comments | The subspecies glauca is the only one found in NC.
