Discussion
Throughout the range of Stillingia sylvatica, leaves vary widely in length/width ratio, though seldom on the same plant.
Some populations in southern Florida have been recognized as Stillingia tenuis or S. sylvatica subsp. tenuis on the basis of linear or narrowly linear-elliptic leaves and slender, reddish inflorescences. Leaf blades of the southern Florida populations vary from linear to broadly elliptic and the reddish cast of the inflorescence is characteristic of only some of these populations and also occurs in S. aquatica. D. J. Rogers (1951) and G. L. Webster (1967) suggested that the characteristics used to define S. tenuis may be the result of introgression of S. aquatica into S. sylvatica, and that the putative subsp. tenuis might be an ecotype of predominantly calcareous soils of southern Florida.
