Discussion
The range of var. lanceolata is poorly documented; it appears to be rather common in Louisiana and extends into Missouri, into eastern Texas, and through Alabama to South Carolina. In its most extreme expression, it is readily distinguished; it intergrades with both var. ovata and var. viridis. The foliage, with its distinctive venation, and the usually small- and few-flowered inflorescences are characteristic. Particularly large, oblong leaf forms of var. lanceolata have been referred to Crataegus interior.
