Leaves are mostly basal, with flat, convolute blades {{convert|10–30|cm|inch|abbr=on}} long and 2–5 mm wide. The inflorescence is a {{convert|10–30|cm|inch|abbr=on}} long panicle of spikelets, each containing one sterile and one fertile flower. The lemma carries a 25–50 mm long awn. Like all Loudetia species, L. simplex uses C4 photosynthesis and occurs in open habitats, often on poor shallow soils. It is a significant weed species.[8] Two subspecies have been described:[1]
In Madagascar, it is one of the dominant grassland species in the central high plateaus,[10] where it occurs on leached, poorly drained soils and is quite fire-resistant. In Malagasy, it is known locally as horona, horo, berambo, kilailay, kirodrotra, or felika. It has only medium value as pasture grass.[11] References1. ^1 {{cite web |title=Grass genera of the world - Loudetia Hochst. |last1=Watson |first1=L. |last2=Macfarlane |first2=T.D. |last3=Dallwitz |first3=M.J. |url=http://delta-intkey.com/grass/www/loudetia.htm |accessdate=4 March 2018}} [1][2][3][4][5][6][7]2. ^1 {{cite journal |last1=Hubbard |first1=C.E. |title=Notes on African Grasses: XVII |journal=Bulletin of Miscellaneous Information (Royal Gardens, Kew) |volume=1934 |issue=10 |year=1934 |pages=425 |issn=03664457 |doi=10.2307/4114347 |jstor=4114347}} 3. ^1 {{cite book |last1=Kull |first1=C.A. |year=2003 |chapter=Fire and the management of highland vegetation |pages=153–157 |title=The natural history of Madagascar |editor-last1=Goodman |editor-first1=S.M. |editor-last2=Benstead |editor-first2=J.P. |publisher=The University of Chicago Press |location=Chicago, London |isbn=978-0226303079}} 4. ^1 {{cite book |last1=Nees von Esenbeck |first1=C.G.D. |year=1841 |title=Florae Africae Australioris Illustrationes Monographicae |oclc=727189281 |url=https://www.biodiversitylibrary.org/page/15463825#page/297/mode/1up |language=Latin}} 5. ^1 {{cite book |last1=Moat |first1=J. |last2=Smith |first2=P. |year=2007 |title=Atlas of the vegetation of Madagascar |publisher=Royal Botanic Gardens, Kew |location=Richmond, Surrey |isbn=9781842461983}} 6. ^1 2 3 4 {{cite web |title=Tropicos - Loudetia simplex (Nees) C.E.Hubb. |url=http://tropicos.org/Name/25514790 |accessdate=4 March 2018}} 7. ^1 {{cite web |title=World Checklist of Selected Plant Families - Loudetia simplex (Nees) C.E.Hubb. |url=http://wcsp.science.kew.org/namedetail.do?name_id=423080 |accessdate=4 March 2018}} }}{{Taxonbar|from=Q15511040}}{{grass-stub}} 3 : Panicoideae|Flora of Africa|Flora of Madagascar |
