Waskuk name=’jarunga.’ Freshly dried foliage is thrown on campfires 
and burned as a mosquito repellent. The smoke has a distinctive 
odor, not at all unpleasant, and is quite effective in ridding an area 
of mosquitoes. Local villagers refer to the plant as ‘bush coil;’ a 
word play on the commercial mosquito punk commonly burned in 
homes.
