    Short General Description
    An erect, relatively small (10-30 cm tall) perennial. Leaves are alternate, broadly lanceolate, three-nerved with short-hairy margins. Lower and upper leaves reduced. Flowerheads are short-stalked and five to twenty. Flowers have white rays and are inconspicuous.
    Reproduction Comments
    The taxon appears to rely primarily upon asexual reproduction, through framentation of existing clones and repeated production of new ramets.
    Ecology Comments
    Occurs primarily in open grassland habitats. Population levels and vigor decline as a canopy of trees or shrubs develops. Seedlings appear to be poor competitors.
