Allozymes in bud tissue and monoterpene contents in xylem oleoresin of slash pine (Pinus elliottii) were analysed from populations across the natural distribution in the southeastern USA, as well as those from other species in the AUSTRALES pines. Allozyme diversity measures of slash pine were similar to those found in other southern pines. The two slash pine varieties, the slower-growing south Florida variety (var. densa) and the more commercial typical variety (var. elliottii), were not separated in the cluster analysis of allozymes. Variation was continuous from south to north in Florida in slash pine, with no distinct transition between the two varieties.
