Worldwide distribution of members of Pooideae species as percentage of the total grass flora. The native distributions of Brachypodium distachyon and a typical cool season Pooideae forage grass, Phleum pratense, are indicated in two different green shadings. Data for distribution is taken from Hultèn and Fries  for P. pratense, and Flora Europaea , Filiz et al.  and data retrieved from the Global Biodiversity Data Portal (data.gbif.org, 2011-11-08) for B. distachyon. This figure (without B. distachyon and P. pratense distributions) was adapted from Hartley  with permission from CSIRO publishing. Pooideae is cited as Festucoideae in the Hartley  original paper.
