Grass & Grasses

This nature challenge focuses on grass, the most prolific plant species in the world, and which we often take for granted. Each day, we walk or play on it, eat the grains produced by it, (wheat, rice, corn, etc) use it for building construction, food production (bamboo, thatching or sugar cane), and use it to bind unstable soil or sand through its tough, but shallow fibrous root system. Generally speaking, grasses rely on wind for pollination rather than insects or other creatures. Check Wikipedia for more information http://en.wikipedia.org/wiki/Poaceae. Your entries might be of manicured lawns, green grassy fields, cereal crops ripening, or Macro shots of grains, stalks of grass, seed heads, etc etc. I will accept photos of cereal grains, but not bread made from them, nor whisky from barley, sugar crystals from sugar cane, as that is going too far from the theme.
