Flax-leaf Whitetop
Sericocarpus linifolius (L.) B.S.P.

Habitat [-]
In New York, this species has been found in openings within pine barrens communities, often growing along roadsides, railroads, or in other disturbed areas. Dry to moist sandy, clay, and gravelly soils of open deciduous and pine woods, oak and pine barrens, roadsides, fields (FNA 2006). Dry woods and open ground (Gleason and Cronquist 1991). Dry woods, thickets and clearings (Fernald 1970).

Associated Ecological Communities [-]
  • Hempstead Plains grassland
    A tall grassland community that occurs on rolling outwash plains in west-central Long Island. This community occurs inland, beyond the influence of offshore winds and salt spray.
  • Maritime pitch pine dune woodland*
    A maritime woodland that occurs on stabilized parabolic dunes. The substrate is wind and wave deposited sand that is usually excessively well-drained and nutrient poor. The community is subject to high winds, sand-blasting, salt spray, and shifting substrate.

    * probable association but not confirmed
  • Mowed roadside/pathway
    A narrow strip of mowed vegetation along the side of a road, or a mowed pathway through taller vegetation (e.g., meadows, old fields, woodlands, forests), or along utility right-of-way corridors (e.g., power lines, telephone lines, gas pipelines). The vegetation in these mowed strips and paths may be dominated by grasses, sedges, and rushes; or it may be dominated by forbs, vines, and low shrubs that can tolerate infrequent mowing.
  • Pitch pine-heath barrens*
    A shrub-savanna community that occurs on well-drained, sandy or rocky soils. The most abundant tree is pitch pine and the shrublayer is dominated by heath shrubs.

    * probable association but not confirmed
  • Pitch pine-oak forest*
    A mixed forest that typically occurs on well-drained, sandy soils of glacial outwash plains or moraines; it also occurs on thin, rocky soils of ridgetops. The dominant trees are pitch pine mixed with one or more of the following oaks: scarlet oak, white oak, red oak, or black oak.

    * probable association but not confirmed
  • Pitch pine-scrub oak barrens
    A shrub-savanna community that occurs on well-drained, sandy soils that have developed on sand dunes, glacial till, and outwash plains.
