Distribution
Pacific: Hawaii present, summit of Mt Pangrango in West Java present, temperate South America present
DOCTERS VAN LEEUWEN l.c. introduced this species from seed he collected in Hawaii and sowed on the summit of Mt Pangrango in West Java, at 3000 m altitude, in 1921. It is maintaining itself there and, although self-pollinating, is visited by Bombus rufipes () and doubtless by nocturnal insects as well. It is a native of temperate South America, widely cultivated and naturalized.
