broad ; spikelets 4-7, about as long as internodes of scarcely brittle axis, 

 4-2-flowered ; glumes of lateral spikelets oblong, 2-3-toothed at tip, 

 teeth triangular-lanceolate, muticous; lower pale unequally 2-3-tooth- 

 ed, muticous; glumes of terminal splkelet, ending in one or two, 

 lanceolate- subulate awns ; loicer 2^(tle mucronate or sJiort-aristate — A-pril 

 and May — 



Var. polyatliera, Boiss. One or more of the teeth of the 

 glume of the lateral spikelets more or less prolonged into an awn — 

 Ascent from Tell-er-Rameh to Nebo (Moab). 



4. iE. eomosa, Sibth. et Sm. 

 .2 to .3. Spike slender, .02 to. 03 long; 

 spikelets 3-4, as long as internodes or long- 

 er, 2-3-flowered ; glumes of lateral spike- 

 lets broad, 2-3-toothed at tip, teeth trian- 

 gular-lanceolate, muticous; lower pale 

 short-bidentate, muticous; awns of glumes 

 of upper spikelets 1-3, the lateral twice to 

 thrice as long as pale, the intermediate 

 much longer ; loioer pale of terminal spike- 

 let toothed or aristate — May— El-Masna'ah 

 (Antilebanon). 



Var. §ubventrico§a, Boiss. Spike- 

 lets 2-3, somewhat ventricose. The glumes 

 of the lower ones with more or less 

 elongated teeth or awns — Palmyra. 



Var. brachyathera, Post. Awns 

 of glumes of terminal spikelet twice to 

 three times as long as pales ; awns of pales 

 very short — El-Ghor. 



Probably further study will show that 

 species 3 and 4 are one. 



* * * All the glumes muticous. Lower pale 

 of upper spikelets, rarely of all, long-awned. 



5. iE. §quarrosa, L. .3 to .4. 



Spike cylindrical, .06 to .15 long, .005 broad; spikelets 

 7-11, 3-5-flowered, about as long as the grooves of the 

 very brittle axis in which they rest, the lower two-flower- 

 ets fertile; glumes oblong-quadrate, scabrous, abruptly 

 truncate at tip, sometimes 3-4-crenulate-apiculate, three- 

 fourths as long as lower pale; lower pale truncate or re- 

 tuse at tip, in the uppermost spikelets with a single, long 

 men, in the loioer with an aicn a little longer than pale or 

 0, muticous — May — El-Masna'ah (Antilebanon). 



6. vE.crassa, Boiss. .3 to. 5. Spike cylindrical, 

 momUform, .00 to .1 long, .007 broad; spikelets 7-9, immersed in the 

 deep excavations of the zigzag, brittle axis, ventricose, 3-4-flowered, a 

 little longer than internode; glumes coriaceous, tomentellous, oblono-- 

 ovate, rounded or truncate at tip and obsoletely or manifestly l-d-de?iticu- 

 'ate; lower pale longer than glumes, oblong at base, tapering into a 3-5- 

 nerved, needle-like awn, in the lower spikelets half as long as pale, and in 

 fh€ upper longer than pale "-^priug-^
