''Triodia'' is a large genus of hummock-forming grass endemic to Australia; they are commonly known as spinifex, although they are not a part of the coastal genus ''Spinifex''.〔 Many of the soft-leaved members of this species were formerly included in the genus ''Plectrachne''.〔Watson, L., and Dallwitz, M.J. 1992 onwards. (The grass genera of the world ): descriptions, illustrations, identification, and information retrieval; including synonyms, morphology, anatomy, physiology, phytochemistry, cytology, classification, pathogens, world and local distribution, and references. Version: 28 November 2005〕 ''Triodia'' is a perennial Australian grass which grows in arid regions and has awl-shaped, pointed leaves. The leaf tips (high in silica) can break off in the skin, leading to infections. Leaves are 30–40 centimetres long. Spinifex has traditionally had many uses for Australian Aborigines. The seeds were collected and ground to make seedcakes. Spinifex resin was an important adhesive used in spear-making. Smoke signals were made to communicate with families and groups a long distance away, as burning spinifex produces a strong black smoke. The species ''Triodia wiseana'' is used for building shelters; bunched together it is used for trapping fish against creek beds. It is called ''baru'' in the languages of the Yindjibarndi and Ngarluma people, the English term is ''hard spinifex''. ;Species〔(【引用サイトリンク】publisher=The Plant List )〕〔(Atlas of Living Australia )〕 *''Triodia acutispicula'' Lazarides *''Triodia aeria'' Lazarides *''Triodia angusta'' N.T.Burb. *''Triodia aristiglumis'' (Lazarides) Lazarides *''Triodia aurita'' Lazarides *''Triodia barbata'' R.L.Barrett & M.D.Barrett *''Triodia basedowii'' E.Pritz. – buck spinifex *''Triodia biflora'' Lazarides *''Triodia bitextura'' Lazarides *''Triodia brizoides'' N.T.Burb. *''Triodia bromoides'' (F.Muell.)
