It may be distinguished from the related Loblolly Pine

 by the somewhat longer, glossier needles and larger red-brown cones, and from Longleaf Pine by the shorter, more slender needles and smaller cones with less broad scales.

There are two varieties:
  • P. elliottii var. elliotti (typical Slash Pine). South Carolina to Louisiana, south to central Florida. Leaves in bundles (fascicles) of twos and threes, mostly threes. Cones larger, 7–15 cm (2.8–5.9 in).
  • P. elliotti var. densa (South Florida Slash Pine or Dade County Pine). Pine rocklands of Southern Florida and Florida Keys, including the Everglades

    . Leaves nearly all in bundles of two. Cones smaller, 5–12 cm (2–4.7 in).


Unlike the typical variety of Slash Pine, seedlings of P. elliotti var. densa pass through a "grass stage", in a manner similar to Longleaf Pine.

The Slash Pine also is known as the Yellow Slash Pine, Swamp Pine, and Pitch Pine, although it should not be confused with the tree more usually called the Pitch Pine
Pitch Pine
The Pitch Pine, Pinus rigida, is a small-to-medium sized pine, native to eastern North America. This species occasionally hybridizes with other pine species such as Loblolly Pine , Shortleaf Pine , and Pond Pine The Pitch Pine, Pinus rigida, is a small-to-medium sized (6-30 meters or 20-100 feet)...
