Polygonella macrophylla, or large-leaved jointweed, is a small slender shrub found in the deep white sands of the Florida Panhandle, on sand pine-oak scrub ridges. The development of this coastal habitat is a major contributor to the decline of the species.
Large-leaved jointweed has alternate, simple, obovate leaves that are 2-6 cm long and somewhat fleshy or rubbery to the touch. Its flowers are small and pinkish to bright red, and because they are borne on racemes their added effect makes them very showy during the fall (October to November) blooming season. (Nelson 1996)
