Pili was harvested by uprooting a bunch. The soil, roots, and flowering spikes were trimmed and the pili bunch was ready for use. They were tied in rows with stems up, placed close together and worked from the bottom of the frame upwards. Pili thatch was replaced every four or five years.Medicinally, burned pili and ashes mixed with coconut was used for ea (thrush) and paoao (childhood disease with physical weakening).The leaves were also used by Hawaiians to stuff mattresses, pad floors, and as a tinder.EtymologyThe generic name Heteropogon is derived from the Greek heteros, different, and pogon, beard in reference to the two kinds of spikelets found in the inflorescence of this species.True to the Latin specific epithet contortus, pili seeds have an unusual habit of contorting when wet in order to burrow head into the soil.www.flickr.com/photos/dweickhoff/5187440899/in/photolist-...nativeplants.hawaii.edu/plant/view/Heteropogon_contortus
