A remarkable grass, well charecterized by its narrow, lax 
panicles; its very slender, twisted but not geniculate awns, which 
are much longer than the spikelets, those of each spikelet closely 
twisted together; and its elongated rachilla joints. The space 
between the flowering glumes is about 4 mm, of which 2 mm 
is the slender, glabrous, rachilla proper, and the other 2 mm the 
somewhat thickened, prominently hirsute callus. The lower one 
or two flowers are perfect, the succeeding two or three stami- 
nate, while the uppermost two glumes are very greatly reduced, 
empty, the last one practically reduced to a very slender awn 
5 to 6 mm in length which terminates the rachilla. 
I was at first disposed to place this apparently undescribed 
genus in the Hufestucae, near the genus Festuca, but it is ap- 
parently better placed in the Aveneae, near the Australian genus 
Amphibromus Nees. It differs from Amphibromus in its more 
numerously nerved empty and flowering glumes, the later 
toothed, not cleft; its twisted but not geniculate awns; and its 
caryopsis, which is obscurely sulcate. Regarding the awns of 
Amphibromus Steudel states “valvula inferior * * * infra 
apicem membranaceum bifidum vel tridenticulatum aristata, 
arista stricta (siccando ad horizontem refiexa nec geniculata).” 
Bentham describes the awns as “florentes * * * medio dorso 
arista torta geniculataque tenui instructae” and in his Flora 
Australiensis as “Flowering glumes * * * with a dorsal 
twisted and bent awn attached at about the middle.”
