I4 6 Rhodora [J LLY 



5 to S dm. high, with scabrous sheaths, rather harsh flat leaves and 

 elongated contracted or open panicles 2 to 3 dm. long. Sheaths 

 overlapping, minutely retrorsely scabrous, ligule membranaceous, 

 acuminate, about 1.5 cm. long. Leaf blades 1.5 to 2 dm. long, 

 about 6 mm. wide, minutely scabrous. Panicles pale, few-flowered, 

 the common rachis glabrous; branches one or two at each node, 

 5 to 6 cm. long, ascending or spreading. Spikelets about 1 cm. 

 long, 7 to 9 flowered; empty glumes unequal, the first 1 mm. long, 

 the second about 2 mm. long; flowering glumes 3 mm. long, truncate, 

 prominently nerved, scabrous throughout. 



Type specimen collected by J. Burtt Davy, No. 6005, July 21, 

 1899, marsh near Cuerneville, Sonoma County, California. 



A peculiar species related to Panicularia fiuitans (L.) Ktze., and 

 /'. borealis Nash, but differing from both in its retrorsely scabrous 

 sheaths ; also from the former in its smaller flowering glumes and 

 from the latter in having the flowering glumes scabrous throughout. 



Panicularia torreyana (Spreng.).

Glyceria elongata Trin. Cram. Suppl. 58. 1836. 



Sprengel's mime, Poa torreyana, should be taken up for this species, 

 as Poa elongata Torr., is invalidated by Willdenow's earlier published 

 species under the same name. 



BROMUS brachyphyllus sp. nov. A nearly glabrous, pale green, 

 caespitose perennial 3 to 7 dm. high, with numerous rather short 

 leaves and very small exserted few-flowered panicles. Culms slender, 

 puberulent just below the panicle, and densely pubescent at and for 

 a short distance below the nodes, otherwise glabrous; sheaths shorter 

 than the internodes, glabrous; ligule rather firm, about 2 mm. long; 

 leaf-blades firm, plane, glabrous, lanceolate, acute, 5 to 15 cm. long, 

 5 to 7 mm. wide ; those of the culm 2 or 3, ascending, the basal ones 

 numerous, the older ones marcescent and persistent. Panicles pale, 

 erect, 3 to 9 cm. long, the branches spreading or ascending, mostly 

 one-flowered. Spikelets 1 to 2 cm. long ; empty glumes unequal, the 

 first very acute, i-nerved, about 6 mm. long, much narrower than the 

 second which is 8 mm. long, 3-nerved, and abruptly acute, both min- 

 utely pubescent: flowering glumes lanceolate, 10 to 11 mm. long, 

 7-nerved, sparingly pubescent throughout with mostly spreading white 

 hairs 0.5 mm. long or less, bearing just below the acute apex a slender 

 straight awn 3 or 4 mm. in length. 



Type specimen No. 2677, W. C. Cusick, collected in open dry pine 

 forests, Black Butte, Crook Co., Oregon, July 19, 1901. 



A remarkable species, at once distinguished from other species in 

 this genus by its comparatively short leaves and very small panicles.
