Spikek^ts in pairs or solitary, alonc^ the unjointed rachis of a 

 simple spike, sessile or minutely pedicelled. Outer glumes 2, 

 equal, callous at base, rigid, strongly compressed, many-

 nerved. — I^ees, I. c. p. 131. 



An elegant grass of the Western district, 1^-2 feet high, with nan*ow

 Outer glumes suboblique, sharply keeled, mucronate-aristate, 

 unilateral at the apex, unequal, the upper often smaller, 

 thinner, nerveless and concave. Flowering glume 5-nerved,
