34 THE FLORA OF THE NORTHERN TERRITORY. 



The awn is altogether pecuhar in position, and its homology is doubtful. 

 It is possible that the genus may ultimately form the basis of an additional 

 subsection of the Andropogoneae.

(Acicarpa, Raddi., 1823 ; Bluffia, Nees, 1835 ; Brachiaria, Griseb., 1853 

 Digitaria, Heist., 1763 ; DUencaden, Rafin., 1840 ; Echinochloa, Beauv., 1812

 1764 ; Syntherisma, Walb., 1788 ; Thalasium, Spreng., 1827). 



Some species contain prussic acid. Most species are good for stock, and 

 would form excellent hay, but should then be cultivated, and cut when in 

 flower. 



Series I. Digitariece. — Spikelets mostly in pairs along the outer or lower 

 side of the simple slender branches of the panicle, one of each pair always 

 pedicellate the other sessile or on a shorter pedicel, the upper ones of each 

 branch occasionally sohtary, the lower ones very rarely clustered. Outer 

 glume usually very small. 



Branches of the panicle often numerous, the lower ones long and verticil- 

 late, the upper ones scattered. — 32. P. papposum.
