LOVEGRASS 
Spikelets few- to many-flowered, the florets usually closely imbri- 
cate, the rachilla disarticulating above the glumes and between the 
florets, or continuous, the lemmas deciduous, the paleas persistent; 
glumes somewhat unequal, acute or acuminate, l-nerved, or the 
second rarely 3-nerved; lemmas acute or acuminate, keeled or rounded 
on the back, 3-nerved, the nerves usually prominent; palea 2-nerved, 
the keels sometimes ciliate. Annuals or perennials with open or 
contracted panicles. 
Palea ciliate on the keels, the cilia conspicuous, usually as long as the width of 
the lemma.
