son (ex Muell.). — Forma australiensis foliis angustioribus spe com- 
plicatis, spiculis 4,5—5 mm. longis, gluma I™ angustius alata brevius 
pectinata a forma indica parum recedit, sed vix varietatis nomen 
meretur. — Bentham in Fl. Austr. 1. e. pedicellum sterilem glumam 
habitus est, sed certe est merus pedicellus, quippe quem rarissime 
spiculam bene evolutam gerentem observavi.
