Microlaena is a genus of grass with a single species Microlaena stipoides or Ehrharta stipoides. It occurs naturally in all states of Australia.
The naked caryopses (grains) are similar in shape to rice grains but smaller, approximately 5 mm long.
The grass grows best in acidic soils and is drought and frost-tolerant. It is found in areas of medium to high rainfall (above 600 mm).
