Large shrub with robust stems to 3.5 m tall, leaves opposite or rarely in whorls of 3. Diagnostic features of the species include ovate-lanceolate, glandular-scabrid, cordate-clasping, mostly opposite leaves emanating a rather penetrating but not unpleasant, citrus-like aroma. Flowering occurs mostly from mid-June to August.
This species is found only on East Maui where it occurs mostly in deep ravines of the outer slopes of Haleakala and on the inner crater walls at elevations ranging from 1,725-2,750 m. The sites occupied by the species receive about 75-215 cm of annual precipitation.
