Lilium catesbaei subsp. asprellum Wherry and L. catesbaei var. longii Fernald have been proposed to account for individuals with leaves concentrated toward the middle of the stem or somewhat wide and lacking basal leaves, respectively. These variants are not emphasized here since both are based primarily on vegetative features that vary greatly in most lilies. Isotypes of var. longii are unremarkable, though with somewhat wide leaves, and the broadly overlapping distribution of this variety with nominate populations (A. E. Radford et al. 1968) strongly suggests that such differences are primarily environmentally induced. Variety longii was described from Virginia, and Fernald’s observation that these northern plants lack basal leaves—which I have not investigated in the field—is unsurprising in those colder climates, and best considered in terms of the normal variation within a fairly wide-ranging species. Although it is not yet rare, widespread alteration of native longleaf pine (Pinus palustris Miller) and slash pine (P. elliottii Engelmann) savanna, especially conversion to even-age pine plantations, is making steady inroads on populations of this most beautiful lily. It is adapted to frequent fires, and their suppression may contribute to this decline. Lilium catesbaei is pollinated primarily by the palamedes swallowtail [Papilio palamedes (Drury), family Papilionidae], the only swallowtail that is widely endemic to this lily’s coastal plain habitat. Spicebush swallowtails (P. troilus Linnaeus) visit the pine lily less frequently, and their smaller size suggests that they are less effective pollinators than the larger palamedes.
