Description
A description of Pityopsis graminifolia is provided in The Flora of North America.
Distribution
Ecology
Habitat
Pityopsis graminifolia is restricted to native groundcover with a statistical affinity in upland pinelands of South Georgia. [1]
Seed dispersal
This species disperses by wind. [2]
Fire ecology
May or may not show fire-stimulated flowering, depending on variety or ecotype. [3] [4] [5]
