The reduction of the raceme, already so marked in Anadelphia, is 
carried to an extreme in Monium, nothing being left of the raceme 
but one sessile bisexual spikelet. In this respect it stands in the same 
relation to Anadelphia as Cleistachne does to Sorghum.—O. STaPr. 
Fic. 1, two-rayed tier of inflorescence ; 2, spikelet opened out, with base of 
awn ; 3, valve of upper floret. All enlarged.
