glumes normally 4, the 2 outer the longest, persistent, 3-nerved, the keel more or less 



winged ; 3rd and 4th glumes small, scale -like ; flowering glumes much shorter than the 



1st and 2nd, 5-nerved ; palea keeled, with 1 ciliate nerve ; iigule membranous, glabrous. 



A. Panicle cylindrical Ph. minor 1. 



A. Panicle ovoid. 



Panicle 2^-4 cm. long ; wing blunt Ph. canariensis 2. 



Panicle 7-10 cm. long ; wing pointed Ph. paradoxa 3. 



* 1 Ph. minor, Retz. Glabrous annual ; panicle oblong-cylindrical, 3-6 cm. long ; 

 2 outer glumes with a narrow scarious dorsal wing ; 3rd glume wanting ; 4th glume 

 bristle-like, £ as long as the flower ; flowering glume hairy. 



Widely spread throughout the settled districts as far as the Flinders Range and the 

 Murray lands. Sept. -Dec. — Mediterranean region. 



* 2. Ph. canariensis, L. Canary-grass. Differs from the preceding in the ovoid or 

 ovoid-oblong panicle ; wing of 2 outer glumes broader, almost entire, obliquely truncate ; 

 3rd and 4th glumes equal, \ as long as flower ; flowering glume hairy. 



Rare in settled districts. Sept. -No v. — Mediterranean region. 



* 3. Ph. paradoxa, L. Differs in the long oblong-ovoid panicle, clasped at the base 

 by the sheath of the uppermost leaf ; 2 outer glumes awned and the wing prolonged 

 upwards into a point ; 3rd and 4th glumes minute, equal ; flowering glume almost 

 glabrous. 



Hindmarsh Valley ; Kingscote, KJ. Nov -Dec. — Mediterranean region. 



23. ANTHOXANTHUM, L. 



(Greek anthos, flower ; xanthos, yellow : colour of the panicle after flowering.) 



* 1. A. odoratum, L. Scented vernal grass. Perennial with hairy leaf blades ; spikelets 

 1 -flowered, compressed laterally, arranged in a spikelike panicle which is 4-6 cm. long; 

 empty glumes 4, the lowest £ the length of the 2nd : the 3rd and 4th smaller, villous, 

 with dorsal awns ; flowering glume still shorter, membranous, glabrous ; stamens 2. 



Mount Lofty Range. Sept. -Dec. — Europe. 



Tribe 6. Agrostideae. Spikelets 1 -flowered, pedicellate ; outer empty glumes 2 ; flower- 

 ing glume usually awned ; palea 2 -nerved. 



24. AMPHIPOGON, R. Br. 



(Greek arnphi, both ; pdgon, beard : because both the flowering glume and palea 



have ciliate awns.) 



1. A. strictus, R. Br. Perennial growing in tussocks, with slender erect stems, subulate 

 leaves and Iigule of hairs ; spikelets 1 -flowered, almost sessile in a dense cylindrical 

 spikelike panicle which is 1^-4 cm. long ; 2 outer glumes thin, subequal, 3-nerved, about 

 4 mm. long ; flowering glume exceeding them by its 3 short rigid ciliate awns or lobes ; 

 palea also deeply divided into 2 similar awns ; styles united near the base. 



Most parts of the State. Sept. -Dec. 



Var. setifer, Benth. Spike tending to ovoid ; outer glumes conspicuously ciliate ; 

 awns longer and more shortly ciliate.
