There can be iittle doubt as to the affinity of this genus with the 
Australian genus Astrebla. This will be at once clear if we imagine the 
lateral lobes of the floral glumes of or as waco adnate to the 
hardened middle lobe up to the base of the awn and both glumes so 
reduced as, in certain species of Astrebla, is the case with the lower. 
The nervation of the floral glumes follows the e type as that o 
Astrebla, whilst the peculiar reduction of the hex fice: the structure 
of the awn oa the toughness of the rhachilla are characters common 
to both genera. The species of Astrebla, which form the basis of the 
genus, were idkadlg baal oy belonging to Danthonia (Lindley, in 
Mitch. Journ. Trop. Austr. 365 and Three Exped. East Austr. 11. 26) 
and Darker himself (in Flor yrenes vii. 602) admitted that ‘it is 
certainly nearly allied to Danthonia, but the central lobe and the un- 
twisted awn induced him to place it (Fl. Austr. lc.) nex o- 
phorum and the inflorescence to refer it later on to Chlorideae (Journ 
06 n. Plant. ii. 1170). As to the inflorescence, it 
may be pointed out that the secund, spiciform raceme characteristic of 
so many Chlorideae also occurs in Danthonia disticha, Nees, whilst the 
valves and the awns approach—the latter apart from its not being 
spirally twisted—much closer to those of Danthonia than of Pappo- 
horum or Enneapogon. I may add — = i florets of Astrebla
