 duced to a membranous pale ; glumes coriaceous, the lower oblong- 

 linear, obtusish, hairy from base to middle, oo -nerved, the upper 

 acute, 3-nerved ; lower pale reduced to a slender, bent and twisted awn 

 which is thrice as long as spikelet ; upper pale ; pedicelled spikelet 

 staminate, not awned — May to August — Dry places; common. 



3. A. aiiiiulatus, Forsk. If Sifun. RuTceih. .3 to .6, tufted;

 lets oblong, obtuse, flattened at back, the lower floweret reduced to a 

 pale; glumes somewhat coriaceous, oblong- linear, ciliate at margins 

 and sometimes at back, the lower oo -nerved, obtuse, the upper acute, 

 nearly nerveless ; lower pale reduced to a twisted and bent, slender 

 awn, 6 times as long as spikelet ; pale ; pedicelled spikelet staminate 

 or neuter, not awned — Spring — Valleys around Dead Sea, and south- 

 ward to Egypt; Jordan Valley. Too near the last. 



* * SinTces pa7iiculate, each pair subtended by a spathe-lilce h'act. 



4. A. birtus, L. 21 Mimdr. Hamas. .4 to 1, tufted; roots

co-nerved, densely hairy, the upper glabrous or sparsely hairy, acutish ; 

 awn geniculate, twisted, pubescent, 4-times as long as linear, 2-dentate, 

 hyaline pale ; glumes of staminate spikelet more acute ; pale awnless — 

 Sj^ring — Dry hills ; coast to middle mountain zone ; common. 



Var. pube§ceii§, Vis. Leaves narrower; spikes fewer, more 

 slender, with shorter appressed hairs; awn 5-6 times as long as pale — 

 Coast; middle mountain zone; Jordan Valley ; Dead Sea, and southward 

 to Sinai. 



Tristram says A. scliceiiaiithuni, L., is found at Gennesaret. 

 16. CHRYSOPOGOIV, Trin. Chrysopogon. 



Spikelets at apex of capillaiy branches of panicle ternate, each 2- 

 flowered, the lower floweret neuter, reduced to a membranous pale ; 

 the middle spikelet sessile, perfect, the lateral pedicelled, staminate. 

 Staminate spikelets: glumes 3, nearly equal, longer than pale, the 

 lower coriaceous, short-bidentate, short-aristate, the upper membran- 

 ous, muticous or short-aristate. Stamens 3. Perfect spikelet : glumes 

 3, coriaceous, longer than floweret, the lower concave, acuminate, the
