Korthals states the natives who accompanied him on Mt. Sakoembang gathered the not yet opened pitchers, as the water which they contained was a medicament against inflammation of the eyes, whereas others cut the opened pitchers as playthings for their children. He describes the habitat as sterile, open and stony. The vernacular name 'daoen sompitan' is translated by him as blow-pipe-leaf; according to dictionaries this is right.
