Pimelea linifolia is an Australian shrub, variously known as Queen-of-the-bush and the Slender or Flax-leafed Riceflower. It is widespread throughout the south and east of the continent and is toxic to livestock. 
The bark can be processed into fine strong thread for catching Agrotis infusa, the Bogong moth. This string, called a 'Bushman's bootlace', is produced by a traditional method that involves wetting, drying, beating and rolling the material.
The plant is prostrate or 1.5 m high. The leaves of the species are narrow or oblanceolate, 2-7 mm, and may be up to 30mm long. Up to 60 white flowers form brachteate heads on glabrous peduncles, bracts are 4 or 8. It was first published in 1793 by James Edward Smith, in his A Specimen of the Botany of New Holland.

We know the bark of the Riceflower as 'Bushman's Bootlace', but here's how to make string: Strip the bark, dry it, place in a stream for about one week, dry in sun, soften by chewing/beating with sticks and stones, roll on the thigh and spin into fine, strong thread.
