S. mexicana is distinguished from the very similar S. sempervirens by an erect habit, less succulent foliage, widely spreading inflorescence branches, and habitat preference. Weakley (2018) also notes that its larger leaves < 3cm wide, whereas those of S. sempervirens > 3 cm wide; and its flowers have only 7-11 rays, vs. 12-17.
