fusiform-terete, tightly enclosed by the lemma and palea; the embryo about 20-35% 
the length of the grain; the hilum linear, nearly as long as the grain. 
Type species: Austrostipa mollis (R. Br.) S.W.L. Jacobs & J. Everett. 
Austrostipa is closest to Achnatherum (Barkworth and Everett 1986; Everett 1990; 
Barkworth 1993) but differs from that genus in having the mature florets generally 
darker and tougher in texture, the lemma margins overlapping, and the callus longer, 
tougher and usually more pungent. Not all species of Austrostipa have all of these 
characteristics, but any one species has most of them. Austrostipa has very variable 
lemma epidermal characteristics. 
Stipa s. str. is characterised by large (often > 1 cm long) chartaceous spikelets with a 
long (frequently >10 cm long) plumose terminal awn and a comparatively short 
callus, and lemma epidermal silica bodies square, rectangular or, rarely, oval.
