 and become flexuous. Originally described from Australia.

9. Eragrostis deflexa sp. nov. 



Plants perennial ; culms tufted, erect or a little decumbent at base, glabrous, firm, 40 to 

 100 cm. tall; sheaths glabrous, pilose at the throat and more or less on the collar; blades 10 to 

 30 cm. long, as much as 4 mm. wide, mostly narrower, flat or involute, tapering to a firm point, 

 glabrous beneath, scabrous on the upper surface and pilose near the base ; panicle oblong, erect, 

 20 to 40 cm. long, 6 to 15 cm. wide, open, the branches in rather distant fascicles, finally spread- 

 ing or deflexed, scabrous, densely pilose in the lower axils; spikelets somewhat compressed, 

 4 to 7-flowered, 5 to 8 mm. long, the rachilla flexuous, glabrous, the florets loosely imbricate, 

 disclosing the rachilla. the pedicels somewhat flexuous, the lateral 2 to 4 mm. long; glumes 

 nearly equal, acuminate, 2.5 to 3 mm. long, the slender point of the first usually somewhat 

 longer than the first lemma and narrower than the second glume, scaberulous on the keel ; lemmas 

 acute, about 2.5 mm. long and 0.7 mm. wide, rather turgid, the lateral nerves faint, finely scab- 

 erulous on the upper part of keel and on the sides near the apex; palea nearly as long as the 

 lemma, finely scaberulous on the keels (fig. 18). 



Near E. lugens but the panicle longer and more oblong, the branches finally deflexed.

10. Eragrostis grandis Hillebr. Fl. Haw. Isl. 528. li 



Plants perennial ; culms in large tufts, erect, stout and tall, as much as i cm. thick at 

 base and 2 meters tall, glabrous ; sheaths glabrous, pilose or glabrous at the throat ; ligule a 

 dense row of short hairs with long hairs as much as 7 mm. long intermixed, these deciduous; 

 blades elongate, usually 5 to 10 mm. wide, sometimes narrower, flat, usually involute toward the 

 slender tip, glabrous beneath, scabrous on the upper surface ; panicle large and open, oblong, as 

 much as 50 cm. long, the branches in more or less distant fascicles, ascending, mostly spikelet- 

 bearing to near the base, pilose in the axils, the axis smooth below, scabrous above as are the 

 branches; spikelets compressed, 5 to 9 mm. long, 5 to 10-flowered, the rachilla joints about 

 0.8 mm. long, scabrous, the lateral pedicels short, about i mm. long; glumes acuminate, 2.5 to 

 3 mm. long: lemmas acuminate or acute, 3 mm. long, loosely imbricate, disclosing the rachilla, 

 glabrous, scaberulous on the keel, the lateral nerves faint but made somewhat prominent by the 

 shrinkage of the inter-nerves ; palea a little shorter than the lemma, scabrous-ciliate on the 

 keel (fig. 19). 



Slopes, ravines, and open forest, mostly in partial shade. Originally 

 described from "High mountains of Molokai! E. and W. Maui!" Two varieties 

 are described, ^ var. oligaiitha from "Molokai! pali of \\'aikolu, and (doubtfully) 

 top of Mount Kaala, Oahu!" and 7 var. polyaiitlia from Molokai.
