Chaptalia albicans was treated by A. Cronquist (1980) as C. dentata (Linnaeus) Cassini. The latter is known only from the West Indies (G. Nesom 1984) and contrasts with C. albicans in having outer pistillate florets with corollas white to greenish (versus white) and laminae (0.2–)0.4–0.7 mm (versus 0.2–0.3 mm) wide, style branches of pistillate florets (0.5–)0.7–0.9 mm (versus 0.8–1.3 mm), cypselae 5.5–7.5(–8.5) mm (versus 8.4–11.2 mm), orange (versus white) carpopodia, and pappus bristles 5.8–8.5 mm (versus 7.8–10.5 mm).
