1 or several imperfect florets above or. below 
the fertile (see also Microchlod). 
Fertile floret with imperfect florets above it. 
Spikelets in long secnnd solitary spikes ; 
valves narrow, firm, glabrous or scaberr^ 
lous, with a short erect awn from the 
notched or subentire tips ... ... 130. Enteropogon. 
Spikelets in digitate, rarely solitary or 2-nate 
spikes ; the florets (particularly the 
barren) much widened upwards or if 
narrow, then delicate and usually with a 
fine awn from below the tips, often ciliate. 
Both glumes lanceolate, usually very nar- 
row, acute and hyaline, keeled ; valves 
or at least some of them awned, very 
rarely submuticous ... 131. Chloris. 
Upper glume broad, dorsally flat or round- 
ed, not keeled, truncate, emarginate 
with a curved mucro or short awn from 
the sinus, scarious ; middle nerve pro- 
minent ; valves awnless ... ... 132. Eustachys. 
Fertile floret with 2 imperfect florets below, 
and 2 or more above it ; spikes solitary, 
secund, compact ; upper glume abaxial, 
with a stiff bristle from the back 133. Ctenium. 
Spikelets with 2 or more fertile florets and without 
imperfect ones belowthem(seealso Chloris sp.). 
Valves awnless or with a rigid mucro or very 
short awn from the acuminate tips (Dactyl- 
octenium sp.), entire or subentire. 
Spikelets in digitate or subdigitate spikes. 
Glumes broad, not keeled ; grain deeply 
hollowed out on the face, subglobose 134. Ccelachyrium. 
Glumes strongly keeled; grain not hollowed 
out. 
Spikes terminated by a spikelet ; glumes 
and valves emucronate or obscurely 
mucronate 135. Eleusine. 
Spikes terminating with a sharp point ; 
upper glume and valves rigidly mu- [nitjm. 
cronate or shortly awned ... ... 136. Dactylocte- 
Spikelets in racemosely arranged spreading or 
deflexed, finally deciduous spikes ; valves 
thin, obtuse or subemarginate and ob- 
scurely mucronulate, much exceeded by 
the long drawn-out glumes ... ... 137. Dine bra. 
Valves finely awned or mucronate, distinctly 
emarginate, toothed or lobed. 
The middle nerve of the valve running out 
into a fine mucro or very short awn ; 
florets equalling or exceeding the spike- 
lets ; spikes rather rigid, long and loose 
or short and contracted on an elongated 
common axis ... ... ... ... 138. Trichoneura. / 
The middle nerve of the valve running out 
into a long awn. 
Spikelets long, very slender, approximate ; 
florets few, exceeded by the glumes ;
