〕 }} ''Microlaena stipoides'' or ''Ehrharta stipoides'' is a species of grass that occurs naturally in all states of Australia as well as in New Zealand, Papua New Guinea, Indonesia and the Philippines.〔(''Microlaena stipoides''. ) Pacific Island Ecosystems at Risk, Hawaiian Ecosystems at Risk. Retrieved 2010-04-03.〕 It has also been introduced into Hawaii and Reunion Island and has been reported as invasive in both.〔〔(PLANTS profile for ''Microlaena stipoides'' (weeping grass). ) USDA PLANTS. Retrieved 2010-04-03.〕 Common names used include weeping grass, weeping rice grass and weeping meadow grass. P. Martin, writing in 2004, commented:〔Martin, P. M. (The potential of native grasses for the use of managed turf. ) 4th International Crop Science Congress, 2004. Retrieved 2010-04-03. 〕 "Although the generic name ''Microlaena'' is strongly defended by Australasian agrostologists (e.g. Wheeler et al. 2002) many European authors treat it as a section of the genus ''Ehrharta'', so that information on the species in question will be found in these sources under the name ''Ehrharta stipoides'' (e.g. Clayton and Renvoize, 1986)." He refers to the species as ''Microlaena stipoides''. The ''Australian Plant Name Index'' and ''Australian Plant Census'' list this scientific name ''Microlaena stipoides'' as currently accepted and under it is subsumed the synonym of ''Ehrharta stipoides'' .〔〔 ==Description== ''Microlaena stipoides'' grows to a height of approximately 0.7 metres and produces delicate, drooping stalks of spikelets.〔 The naked caryopses (grains) are similar in shape to rice grains but smaller, approximately 5 mm long, with a mass that varies widely, ranging from 1 mg to 7 mg.〔〔〔(''Microlaena stipoides'' (Weeping Grass). ) Taroom Shire Council Land Care. Retrieved 2010-04-03.〕 The grass grows best in acidic soils and is drought- and frost-tolerant.〔(''Microlaena stipoides'' (Microlaena or Weeping grass) ) ''Rangelands Grassed Up''. Australia: NSW Department of Primary Industries. Retrieved 19 June 2013〕 In Australia it is found in areas of medium to high rainfall (above 600 mm ''per annum'') and the leaves normally remain green all year.〔Davies, C. L., D. L. Waugh and E. C.
