Maianthemum comaltepecense is a rare perennial, terrestrial herb found as an understory species in moist forests[1] and endemic[2] to southwest Mexico.

Fruits are 3-lobed, 6–9 mm across, ripening to purple with white spots.

[1] Maianthemum comaltepecense is known only from one population in Oaxaca, Mexico.
