72, CHONDROLZAENA, Nees. 
Spikelets in pairs or solitary, along the unjointed rachis of a 
simple spike, sessile or minutely pedicelled. Outer glumes 2,

Outer glumes suboblique, sharply keeled, mucronate-aristate, 
unilateral at the apex, unequal, the upper often smaller, 
thinner, nerveless and concave. Flowerimg glume 5-nerved, 
keeled, mucronate-setigerous, ciliate on the keel; palea 2-

secund spikelets.—1 Cape species. 
74. KQ2HLERIA, Pers.

in close, spike-like panicles. Outer glumes 2, unequal or 
subequal, membranous, keeled. Flowering glume membra-

European grass, is common.
