Australian spinifex grasses: new names in Triodia for Monodia and Symplectrodia

摘要: The Australian spinifex grasses comprise an endemic radiation (69+ species) of morphologically and ecologically distinctive plants. Many species are long-lived hummock-forming perennials that bristle with needle-like leaves. Ecologically, they resemble sclerophyll shrubs rather than (Rice & Westoby 1999). They widespread in dry communities, especially the eremaean monsoonal (savannah) biomes, where often dominate landscape, particularly on oligotrophic (sandy skeletal) substrates. Across nearly one-third continent, plays a dominant role structuring communities their fire regimes, directly influencing habitat dynamics many animals, including endangered (Allan Southgate 2002, Brown et al. 2009, Dickman 2011).
