rolled round the flower, with a terminal undivided bent awn spirally 
twisted below the bend. 
Palea enclosed in the flowering glume. 
Lodicules usually large. 
Anthers usually tipped with a tuft of hairs. 
Styles distinct. 
Grain narrow, enclosed in the hard upper glume, but free from it. 
A short continuation of the rhachis of the spikelet above the articula- 
tion forms usually a stipes to the flower and fruit, falls off with it, and 
is usually ciliate with short hairs; the awn is more or less distinctly 
articulate on the flowering glume, but usually remains attached to it 
after it falls. 
The genus Stipa contains about 100 species. Australia claims 
fifteen, New Zealand two, one* of which is also found in Australia, 
while the others are natives of America and Asia. ‘The United States 
has twenty-three species, and some of these have well marked varieties. 
In that country they are not, at least at present, accounted of much 
importance to the grazier, and no experiments appear to have been 
undertaken to determine their specific fodder value.

produced into hyaline lobes or entire. Palea very small or

1. Stipa elegantissima, Labill. 
Botanical name.—Stipa—Latin for “tow,” in allusion to the feathery 
awns of the original species (S. pennata). In some species the awn 
is naked. Elegantissima, superlative of elegans, signifying handsome. 
This is a most beautiful grass. 
Where fi gured.—Labillardire.
