_ . 3. FESTUCA L. 



Spikelets few to several-flowered, the rachilla disarticulating above the glumes and 

 between the florets ; glumes narrow, acute, unequal, the first very small in some species ; lemmas 

 rounded on the back, membranaceous or somewhat indurate, 5-nerved, the nerves obscure in some 

 species, acute or rarely obtuse, awned from the tip or rarely from a minutely bifid apex. Annual 

 or perennial low or rather tall grasses of varied habit, the spikelets in narrow or open panicles. 



Plants perennial; panicle open, the branches spreading i. F. hawaiiensis. 



Plants annual ; panicles narrow, the branches appressed. 



Lemmas ciliate toward the apex 2. F. megalura. 



Lemmas not ciliate 3. F. bromoides. 



1. Festuca hawaiiensis sp. nov. 



Plants perennial ; culms tufted, erect, glabrous, about 1.5 meters tall, rather stout; sheaths 

 glabrous, shorter than the internodes ; ligule membranaceous, i to 2 mm. long, the margin 

 lacerate ; blades narrow, 20 to 30 cm. long, 3 to 5 mm. wide, tapering to a slender involute point 

 and more or less involute at the base, smooth on the lower surface, scabrous on the upper; 

 panicle open, 30 to 40 cm. long, erect, the branches in distant fascicles, the axis terete and smooth 

 below, angled and scabrous above ; branches spreading or drooping, slender, scabrous, about 5 in 

 the lower fascicle, 8 to 15 cm. long, branching above the middle, bearing 3 to 5 spikelets on 

 slender pedicels 5 to 10 mm. long, the upper fascicles of about 3 successively shorter branches; 

 spikelets several-flowered, the rachilla appressed-hispidulous ; glumes narrow, glabrous, scabrous 

 on the keels near the apex, the first i-nerved, 3 to 5 mm. long, the second 3-nerved, 6 to 7 mm. 

 long; lemmas narrow, 7 to 9 mm. long, i to 1.5 mm. wide, rounded on the back, faintly 

 5-nerved, scabrous, acuminate or extended into an awn about i mm. long ; palea scabrous, as 

 long as the lemma and closely fitting to its edges (fig. 4). 



Type in the U. S. National Herbarium, no. 836317, collected in rich soil on 

 a moist wooded hill (Puu Huluhulu), Humuula Sheep Station, Hawaii, at about 

 2000 meters elevation, August 27, 1916, by A. S. Hitchcock (no. 14446). 



The species was abundant here, growing in bunches 0.5 to 2 meters tall, 

 apparently indigenous. 



^^'hat appears to be the same species was collected in an over-ripe condition 

 on the Hualalai Mountains, in woods at 1000 meters elevation (Hitchcock 14536). 



This is the species described as Festuca drymeia Mert. & Koch by Hille- 

 brand** who says, "without label ; probably collected in Ulupalakua, ]Maui." Hille- 

 brand's specimen, kindly submitted to me by Dr. Diels, is labeled from "Maui et 

 Hawaii." It differs from F. drymeia of Europe in the larger scabrous spikelets 

 and the absence of rhizomes. 



2. Festuca megalura Xutt. Journ. Acad. Nat. Sci. Phila., II. i :i88. 1848. 



Plants annual ; culms 20 to 50 cm. tall, tufted ; sheaths and blades glabrous ; panicle 

 narrow, 7 to 20 cm. long, the branches appressed; spikelets 4 or 5-flowered ; glumes glabrous, 

 very unequal, the first mostly less than 2 mm. long, the second 4 to 5 mm. long ; lemmas linear-
