Recent studies concluded that L. diffusus should be emended to apply only to populations in the Florida panhandle and nearby states (Nevado et al. 2024; Bridges & Orzell 2024). Two related studies proposed alternative taxonomies: 1) L. cumulicola should be reinstated and its circumscription expanded to include all peninsular Florida populations along with recognition of infraspecific taxa (Nevado et al. 2024) or 2) recognize the peninsular Florida populations as four separate species (Bridges & Orzell 2024). (See also: Small 1933; Dunn 1971; Isely 1990; Duncan & McCartney 1992).

Variety clausa has been recognized by serotinous cones resulting in even-aged stands and more common in the peninsula. Variety immuginata has been characterized by non-serotinous cones resulting in mixed-age stands and more common in the panhandle (Ward 1963). However, due to widespread variability in cone morphology, Myers (in Myers & Ewel 1990) wrote "there seems to be no compelling reason to distinguish two varieties".

This species concept includes P. elliottii var. densa (or P. densa), distinguished from the typical variety by having denser wood, a grass-like seedling stage, needles usually in fascicles of 2 with a thicker hypoderm, and opened cones averaging 10.1 cm long with a rounded bottom (Little & Dorman 1952, 1954; Ward 1963). Ward (1963) gave its distribution as Levy, Polk, Osceola, and Volusia Cos. southward, overlapping with the distribution of var. elliottii in central Florida. Studies by Squillace (1966) and Schmidtling & Hipkins (2001) found no clear distinction, with variation appearing continuous between the two varieties (see also Dvorak et al. 2000; Hernández-León et al. 2013). Pinus elliottii is closely related to P. caribea (Schmidtling & Hipkins 2001; Schmidtling 2007). Four samples identified as P. elliottii var. densa (from Big Pine Key, Miami-Dade Co, and Pinellas Co.) were recovered as monophyletic and sister to P. palustris based on nuclear DNA sequences, while plastid DNA suggested the sample from Pinellas Co. may have hybridization history with P. echinata (Gernandt et al. 2018).

FACU

This species is characteristic of fire-maintained uplands in central and northern Florida, supporting a uniquely diverse ecosystem. Historically, the tree was widely used for naval stores and logging. Over 90% of the original stands of longleaf pine in Florida (and elsewhere) are gone, most of it lost by the 1970s (Smith et al. 2000; Frost 2006; Hanberry et al. 2023). Many of these areas were planted with loblolly, slash, or sand pine. There have been appreciable efforts made to restore some longleaf pine habitats. Though a primarily upland species, in 1768 Miller was informed the species inhabited swamps and thus gave the epithet 'palustris' (Ward 1974).

The hybrid P. x sondereggeri is a cross between P. palustris and P. taeda, and it was allegedly planted in Olustee (Kraus 1963).
