Spikelets 2-nate, one sessile, the other pedicelled, similar in shape, 
different in sex, except the lowermost 1 or 2 pairs of each raceme 
which are (with occasional exceptions in D. annulatum) homo- 
gamous ( $ or neuter), in many- jointed shortly peduncled subdigi- 
tate, rarely subpanicled or racemosely arranged, racemes ; joints 
and pedicels filiform, solid, disarticulating subhorizontally except 
the lowest barren pairs ; fertile sessile and pedicelled spikelets de- 
ciduous, the former with the adjacent joint and pedicel. Florets 2 
in the fertile sessile spikelets (lower reduced to an empty valve,
