Where it grows wild

Records cluster on the high plateau and slopes of Puebla, Tlaxcala, Hidalgo, western Veracruz and northern Oaxaca, in open grassland, scrub and pine-oak clearings on well-drained volcanic or rocky soil. Habitat detail is inferred from the record sites and the genus; little species-specific ecology is published.

Recorded at 1,394–2,828 m, median 2,396 m.
