Type specimen collected on hills about Oakland, California, by H,N. IJolander, 

 in 1862 (No. 1505) ; also collected in Oregon by T. J. Howell (Nos. 20 and 23). 

 This 8]>ecies is described by Thurber as Festuca scahreUa in Wats. Bot. Cal. 14. 

 318 (1880). . It differs from Torrey's species in its much larger size, open panicle, 

 and larger florets.

 to 3 feet high ; leaves G to 8 inches long, 2 to 3 lines wide, flat, acuminate ; sheaths

 spreading, nodding; lower branches in pairs, subdivided above the middle; spike- 

 lets mostly 3-lIowered; empty glumes very unequal, the lower one small and one- 

 half as long as the upper, which is lanceolate, 3-nerved, smooth, and more than 2 

 lineslong; floral glumes 3 linos long, 3-nerved, nearly smooth, acuminate, usually 

 terminating in a very short (i line), weak awn; palet as long as its glume, 

 Bcarioua, nunutoly scabrous. 



Collected in 1891 in the liincon Mountains, Arizona, by G. C. Ncalley (No. 177). 

 I refer this with much doubt to the F. fratercula of Ruprecht, as cited by Fouruier 

 (Mex. PI. ii, 124), but have seen no authentic specimens. 

 Pestuca joneaii sp. uov. Culms variable, from slender to stout, 2 to 3i feet high, 

 smooth, leafy; leaves of culm 3 to 5, flat, 5 to 12 inches long, 2 to 4 lines wide, 

 attenuate; sheaths shorter than the internodes; ligule short, obtuse; panicle 

 ample, very open, 6 to 12 inches long, the branches mostly in pairs at the 5 to 8 

 distant nodes, slender, floxuous, 3 to 6 inches long, spreading, when old some- 

 times reflexed, divided near the middle; spikelets numerous, about i inch long 

 including the awns, 3- to 5-flowered; empty glumes narrowly lanceolate,unequal, 

 the upper 2 to 2^ lines long, the lower one-third shorter, both attenuate; floral 

 glume about 2J lines long, lanceolate-acuminate, 3-nerved, minutely scabrous, 

 terminated with a slender awn longer than the glume; palet e(jualiug its glume, 

 with 2 narrow teeth at the apex. 



Type specimen collected by M. E. Jones in southern Utah in 1880. Other 

 epecimons have been collected from Utah and Idaho to the coast of California 

 and Washington. It has sometimes been distributed as Festuca occidentalis Hook. 

 ConH])i(^(ious from its spreading panicle, and long, often wide, flaccid leaves. 

 Pestuca scabrella major var. nov. Culms closely tufted, stout, 2 to 3 feet high, 

 rather rigid; radical leaves numerous, one-half as long as the culm, erect, rigid, 

 scabrous, narrow, conduplicate or involute, many at the base breaking early 

 from their sheaths; ligule very short, truncate, ciliate; panicle 5 to 9 inches 

 long, narrow, loose, the branches mostly in rather distant pairs, erect, tlie lower 

 2 to 3 inches long, branching near the middle, with a few large, turgid spike- 

 lets 5 to 6 lines long, 2- to 4-flowered; empty glumes thin, membranaceous, the 

 lower nearly 3 lines long, 1-nerved, the upper broader, 3-uerved below, nearly 

 4 lines long, both acute; floral glumes nearly 4 lines long, scabrous, puncticulate, 

 attenuate, acute, much thicker than the empty glumes, 5-nerved ; palet one-fifth 

 shorter than its glume, scabrous on the keels and near the bifid tip; internode of 

 rachilla i line long, hispidulous.
