I noticed this tiny flower/grass in the village Burial Ground this morning.
Wikipedia says "Luzula Campestris commonly known as Field Woodrush or Good Friday Grass is a flowering plant in the rush family. 
It is also one if the plants known as Chimney Sweeps or Sweeps Brooms because of it's brush like appearance of their flowers.
A common plant found in all types of grassland and cultivated areas such as lawns, golf courses and fields".    Must admit I hadn't noticed it before.
