Where it grows wild

Little is published beyond the description. As a former Hoffmannseggella it grows on exposed granite or quartzite outcrops, rooting in crevices and thin pockets of grit in full sun and wind.

No GBIF records carry an elevation. The Guanhães region lies roughly at 800–1100 m, so it is likely a mid-elevation plant, but this is an inference from the name.
