172 GRAMINEAE, | Danthonia. 
a mucro; callus at the base of the glume, hairy. Palea broad, hyaline, 
2-keeled. Lodicules 2. Stamens 3. Styles distinct; stigmas plumose, 
Grain oblong, ellipsoid, or obovoid, free within the flowering glume and 
palea. 
Species not far from 100, widely dispersed in both hemispheres, but chiefly in the 
South Temperate Zone, particularly abundant in Australia, New Zealand, and South 
Africa. Of the 13 species found in New Zealand, 2 extend to Australia, the rest are 
endemic.
