Hyparrhenia is a genus of grasses. Many species are known commonly as thatching grass. They are mostly native to tropical Africa; some can be found in warmer areas in temperate Eurasia, Australia, and Latin America. These are annual and perennial bunch grasses. The inflorescence branches into twin spikes of paired spikelets. see Andropogon Elymandra Exotheca Hyperthelia Parahyparrhenia • Hyparrhenia abyssinica - Exotheca abyssinica • Hyparrhenia archaelymandra - Elymandra archaelymandra • Hyparrhenia baddadae - Elymandra grallata • Hyparrhenia cornucopiae - Hyperthelia cornucopiae • Hyparrhenia dissoluta - Hyperthelia dissoluta • Hyparrhenia djalonica - Parahyparrhenia annua • Hyparrhenia edulis - Hyperthelia edulis • Hyparrhenia eylesii - Elymandra grallata • Hyparrhenia grallata - Elymandra grallata • Hyparrhenia jaegeriana - Parahyparrhenia annua • Hyparrhenia lithophila - Elymandra lithophila • Hyparrhenia macrolepis - Hyperthelia dissoluta • Hyparrhenia monathera - Exotheca abyssinica • Hyparrhenia pusilla - Andropogon pusillus • Hyparrhenia sulcata - Parahyparrhenia annua
