Plants perennial; culms in dense tufts, slender, erect or spreading, 10 to 30 cm. tall; 

 sheaths glabrous, pilose at the throat ; blades mostly clustered at the base of the plants, 5 to 

 15 cm. long, I to 2 mm. wide but mostly narrowly involute, tapering to a slender point, glabrous 

 beneath, scabrous on the upper surface; panicle erect, narrow and more or less spikelike, often 

 somewhat interrupted, 5 to 15 cm. long, mostly less than i cm. wide, the branches short and 

 appressed, the lower i to 2 cm. long; spikelets mostly 6 to 8-flowered, about 5 mm. long, the 

 florets scarcely disclosing the glabrous rachilla ; glumes acuminate, 2 to 3 mm. long, the first 

 often longer than the first lemma; lemmas about 2 mm. long, rather obtuse, glabrous; palea 

 nearly as long as the glume, scabrous on the keels (fig. 20). 



Open dry ground. Originally described from "insulis Sandwicensibus."

 what pubescent on the collar, otherwise glabrous ; ligule a ciliate membrane less than 0.5 mm. 

 long; blades slender, erect, involute, i to 2 mm. wide, glabrous on lower surface, villous on 

 upper surface near base, scaberulous near the slender sharp tip ; panicle slender, spikelike, mostly 

 rather dense, 15 to 30 cm. long, about 5 to 8 mm. thick, the axis and pedicels scabrous or 

 puberulent ; spikelets about i cm. long, mostly 8 to lo-flowered, longer than the pedicels; glumes 

 about equal, atout 5 mm. long, as long as or longer than the first floret, attenuate-pointed, 

 scaberulous on the keel toward the tip, the first i-nerved, the second 3-nerved, lemmas acute, 

 rather faintly 3-nerved, about 3 mm. long, faintly scaberulous on the keel toward the tip, 

 imbricate, hiding the rachilla; palea shorter than the lemma, scaberulous on the keels (fig. 21).
