form. Spikelets subulate (not including awns), shorter than internodes ; 

 glume minute, tooth-like ; awn as long as lower pale, straight — April to 

 June— Dry hills; coast to .middle and subalpiue mountain zones. 



90. mOIVERltlA, Pal. Monekma. 



Spikelets solitary, immersed in excavations of the axis, 1-flowered, 

 with sometimes a rudiment of a second. Glumes coriaceous, those of 

 the terminal spikelets 2, opposite, of the lateral spikelets 1, covering 

 the floweret. Floweret membranous, parallel with the axis; lower pale 

 acute, upper 2-keeled, 2-toothed — Annuals. 



M. cyliudrica, Willd. .05 to .2; culms clustered, ascending 

 or erect, often branched, thickish. Leaves linear, flat, at length invo- 

 lute. Spike .05 to .1 long, .0015 thick, straight or sometimes slightly 

 incurved; spikelets somewhat longer than internode; glumes lanceolate, 

 acute, pungent; at first spreading, then closely appressed to axis; 

 pales hyaline, the lower lanceolate, acute — May — Sandy places and 

 waste fields ; coast. 



91. HORDEUlfl, L. Barley. ShaHr. 



Spikelets 3 in each excavation of the rachis, each 1-flowered, the 

 lateral stipitate, staminate or neuter, the intermediate perfect. Glumes 

 awn-like, 3 pairs, side by side toward the outer aspect of the spikelets, 

 forming a sort of involucre. Pales herbaceous, opposite the rachis; 

 the lower (outer) pale of the fertile floweret long-awned from its apex, 

 ITpper pale membranous, 2-keeled, scabrous or ciliolate at keels — An- 

 nuals or perennials with spiked inflorescence. 



* Annuals. 



1. H. I!liaburen§e, Boiss. .5 to 1, erect. Leaves flaccid, 

 linear, acuminate. Spike (with awns) .2 to .3 long, .008 to .01 broad, 

 flattened, 2-ranked, with brittle axis; lateral spikelets stipitate, stami- 

 nate, mulicous; perfect spikelet in the middle, sessile, aristate; glumes 

 lanceolate-subulate at base, ciliate-'plumose, the longer awns once and a 

 half as long as sterile flowerets, lower pale of lateral spikelets muticous; 

 awn of fertile pale scabrous, .15 to .3 long — April and May — Et-Tih; 

 Judajan Desert; Mt. Tabor; Gilead to Damascus, Palmyra, and east- 

 ward. This species may be the original of the cultivated species H. 

 distichum, L. and U. vulgare, L. (the 4 ranked Barley). 



2. H. murinum, L. .1 to .4, ascending. Spike cylindrical, 

 .05 to .1 long, .02 to .035 broad, dense, with brittle rachis; the fertile 

 and sterile spikelets nearly of equal breadth; glumes lanceolate and ci- 

 liateatbase, tapering into awns, half to twice as long as lower pale ; 

 awn of lower pale of all spikelets twice as long as glumes — Spring — 

 Roadsides and waste places; everywhere to subalpine regions. 



3. H. maritimum, With. .1 to .4, usually tufted, genicu- 

 late-ascending. Spike terete, .02 to .04 long, .01 broad, rachis scarce- 

 ly brittle; the sterile spikelets smaller than the fertile, sometimes 0'^ 

 glumes scabrous, awl shaped from base, 2-3 times as long as floweret; 

 awn of lower pale of fertile floweret somewhat longer than glumes — 

 Spring — Coast to middle zones and tablelands, especially in salty 

 places.
