Tripogonella loliiformis

Tripogonella loliiformis, formerly Tripogon loliiformis and commonly called five-minute grass or rye beetle-grass, is a small, tufted, drought-tolerant perennial grass in the Poaceae family native to Australia, where it occurs across most of the mainland in semi-arid and arid regions, on stony hills, gibber plains, shallow soils over rock and disturbed roadsides. It is one of the most extreme desiccation-tolerant ('resurrection') angiosperms, capable of drying to apparent death and reviving within hours of rainfall. The plant forms compact, wiry tussocks 5 to 30 centimetres high, with very narrow, tightly inrolled, glabrous to slightly hairy leaves 2 to 10 centimetres long. Each culm bears a single, slender, terminal, one-sided spike-like raceme 3 to 10 centimetres long; the spikelets are sessile, appressed in two rows along one side of the rachis, and contain three to seven florets. The lemmas are short-awned and the paleas conspicuously two-toothed at the apex. The fruit is a small narrow caryopsis. The species has become a model plant for research into vegetative desiccation tolerance.
