*CHARACTER NOTES 
#6. Plant colour yellowish green refers to the lighter grass green colour
common in pasture grasses. Deep green is seen after \i{}Poa\i0{} lawn has
been fed nitrogen and often in shade species. Bluish gray green refers to the
typical glaucous colouring that results from a waxy surface. It is
conspicuous in \i{}Festuca\i0{} "glauca" of the turf trade, but common in
several species. 
#8. Densely tufted was originally intended to distinguish bunch grasses from
other species, but it applies to Arctic caespitose species in subgenus
\i{}Festuca\i0{}. Species which are normally loosely tufted may appear
densely tufted when growing in confined spaces. 
#9. The character was originally to distinguish bunch grasses, but is useful
in distinguishing some other taxa, e.g. erect \i{}F. brachyphylla\i0{} from
somewhat decumbent \i{}F. edlundiae\i0{}. 
#10. This character was included to test its usefulness in distinguishing the
rough "royal fescue" of Alberta, so called because of its deep purple
sheaths. It has been found to be rather variable. 
#11. Species which normally have well developed rhizomes may not develop them
when growing in rock crevices. Also, rhizomes may be absent from young
plants, or specimens collected without sufficient root material.

#32. State 2: see Aiken and Darbyshire 1990, Plate 3. 
#35. Some species, such as the rough fescues and \i{}F. rubra\i0{} have very
strongly defined ribs. In other species, especially Arctic and alpine taxa
the degree of development of the ribs appears to be somewhat related to the
age of the leaf. 
#36. The "somewhat inflated" condition was used to test a character suggested
by Frederiksen (1977) to distinguish \i{}F. hyperborea\i0{}. It is of limited
use. 
#55. Considers condition where most spikelets of an inflorescence are
vegetatively proliferating. 
#69. Character refers to elongated lemma callus of \i{}F. subuliflora\i0{}.
