RECOGNITION. Recognised in the genus Lasjia by the combination of the following characters: indumentum of persistent simple matted hairs throughout the plant (on the hardened stems, mature leaves, inflorescence axes, pedicels and abaxial tepal surfaces) and the very short pedicels less than 3.5 mm long; in addition, the new species usually has whorls of 5 leaves, obovate to elliptic laminas and a retuse to emarginate apex, and erect inflorescences to 6 cm long.
ETYMOLOGY. Named for the grey leaves in the field.
