64. MONERMA Beauv.

 forming a slender cylindrical spike, and placed with the floret dorsi-ventral to 

 the rachis as in Lolium. Glume of lateral spikelets solitary, coriaceous, gradu- 

 ally acuminate, longer than the lemma, the terminal spikelet with two glumes. 

 Lemma membranaceous. Low cespitose annuals. — Species 3, of the Okl World, 

 1 introduced in California. (Greek monos, single, and erma, support, on 

 account of the single glume.)

 Lemmas much smaller than the glumes, hyaline, keeled. Low annuals with 

 slender spikes. — Species 5 or 6, eastern hemisphere, 1 introduced in California.
