Discussion
Variety occidentalis and Kalmia polifolia are strikingly similar. Both have the same general habit and size and are very similar in most morphological characteristics. These taxa are easily separated by the revolute leaf margins and small stalked glands along the leaf midrib in K. polifolia, which are lacking in var. occidentalis (J. E. Ebinger 1974). Hybrids between them are sterile (R. A. Jaynes 1988).
