24b. Pinus elliottii var. densa Little & Dorman, J. Forest. (Washington). 50: 921, fig. 1, 2. 1952.

South Florida slash pine

Pinus densa (Little & Dorman) de Laubenfels & Silba

Seedlings with vertical growth interrupted by grass stage, stem then more thickened, fascicles much more numerous and crowded around bud, and other buds more approximate on stem. Leaves mostly in 2s, sometimes in 3s on same shoot, resin canals per leaf 3--9, hypodermis (2--)3--4(--5) cell-layers thick. Seed-cone base mostly rounded when open.

Flatwoods, mostly over limestone; 0--10m; Fla.

The name Pinus caribaea Morelet has been applied in error to P . elliottii var. densa . This variety is best distinguished by its wood, which is heavier and harder than that of typical slash pine, and by its having a grass stage comparable to that of P . palustris . This variety is not used for naval stores as is the type variety; neither is it commercially planted.
