TR1AND. DIGYN. 39 



spik-eleis large, but varying as well as the pedicels in roughness and 

 pubescence, often smooth. The lower leaves are complicate, the 

 upper ones more or less plane. The colour of the plant is gene-" 

 rally glaucous green, the spikelets more or less tinged with red. 

 The F. glauca of Mr. D. Don's unpublished MSS., which he considers 

 to be that of Lamarck and Decandolle, has no character which is 

 not included in my F. duriuscula, nor any mark that appears to me 

 to require particular notice. Host and Schrader and Gaudin have 

 added greatly to the species (if sueh they can be failed) of this tribe 

 of Festuca,'. 



3. F. iromoides (barren Fescue- grass), panicle secund racemose, 

 flowers shorter thaii the awn monandrons, culm above leaf- 

 less. Light/, p. 102. E. B. t. 141 1. 



HAH. Dry pastures, but not common, Lightf. Frequent on walls 

 about Ediiib., Dr. Yule. Walls and dry sandy places about Glasg., 

 but rare, Hopk. Fl. June. . ( <$ , Schrad.) 



Six to eight inches high. Leaves linear, setaceous, complicate. Cal. 

 valves unequal, lanceolate-acuminate, nerved, rough at the keel. 

 Florets about six in each spikelet. Ext. valve of cor. linear-lanceo- 

 late, scabrous, tapering into a straight awn, twice the length of the 

 valve. 



4. F. Myurns .(Wall Pescue- grass), panicle secund elongate 

 contracted, flowers shorter than the awn monandrousj culm 

 leafy in its upper part. E. B. t. 1412. 



HAB. Walls and barren places, but not common, Hopk. N. of For- 

 fur, Mr. Arnott. FL June. . 



Much resembling the last, but taller. One foot high. Leaves shorter, 

 their sheaths longer and springing even from the upper part of the 

 culm. Panicle often 4 5 inches long. Cal. valves andflorels nar- 

 rower, rather more scabrous, awns longer. 



5. F. gigantea (tall Fescue-grass), panicle branched drooping 

 towards one side, spikelets lanceolate compressed^ flowers 

 shorter than the awn, leaves linear-lanceolate, ribbed. Light/. 

 p. 104 (Bromus gig.). E. B. 1. 1820. 



/3. triflura, panicle more erect, slenderer, with three flowers, leaves 

 narrower, F. triflora. E. B. t. 1918. 



HAB. Shady woods, as Armaddy in Nether Lorn, Lightf. Moist woods 

 and hedges, frequent about Glasg., Hopk. JB. On the banks of the 

 Esk, near Forfar. Fl. July, Aug. 7/ . 



A tall grass, 3 4 feet high, with broad leaves, having the habit of 

 Bromus, but placed by Smith among the Festuca on account of the 

 absence of the fringe to the inner valve of the cor. Panicle large. 

 Spikelets from 3 6 florets. Cal. val 'es very unequal, larger one 

 with three ribs. Outer valve of cor. lanceolate, obscurely ribbed, 

 nearly glabrous, membranous at the edge upward. Awn very long, 

 inserted a little below the bifid point. I fear the F. triflora is only 

 a starved var. of this plant ; since I can find no difference but what 

 I have indicated above.
