San Fram:iseo niul elsewhere (Ilohuulcr) ; Oregon (Sjia/di,!!/) ; ^Va^>Ilin,t,'t^)n Territory {Coojicr) ; 

 eastwanl to New Kiiglaml. A native of Kuroiie and oilier temperate eoiiiitiies, also largely in- 

 trodueeJ as a weeil. Tiiis, wliieli is known to eultivators as "Coueli-" "Quaek-" and "Qiiiteh- 

 grass," is in its indigenons forms ealled " Blue-joint," "Hunch-grass," and " Lagoon-grass" by 

 western settlers and lienlsinen. It apjiears to he niueh more ahundant in the Rocky Mountain 

 region than farther west, and presents a great variety of puzzling I'orms, the dilliculty in deter- 

 mining these heing inereased by the general laek of roots to the siieeimens.

2. T. caninum, Linn. Culms 1 to 3 feet lii^;li, geniculate below : k-aves Hat 

 or loosely couvulute, pubescent above and like tlie .shcatlis smooth below : spike 

 more or less uodclin;^ at least not strict ; s[)ikelets 3 - G-llowered, mostly much 

 longer than the joints of the rhachis : glumes 5 - 7-nerved, with long awns or merely 

 acuminate : florets somewhat distant ; lower palet S-nerved near the tip, with mostly 

 spreading awns twice their own length. — Agropifrum raninum, Keichenb. Icon. Fl.

Big Trees, Calaveras County (Ilillcbmnd); Carson's Pass, at 8,000 feet altitude (Brewer) ; fre- 

 quent in Colorado and Nevada, and eastward to New England. Like the pivceding very variable, 

 and in European works several nominal species are made from foinis of it. The only specimens 

 collected within the State referable to this species are mountain forms bv Ilillebrand and Brewer. 

 The latter is the same as 381 of Barry's llocky Mountain <'oii.vii,m of 18(n, referred by Dr. Cray 

 to 7'. ayiloiwitlis, Tincz., but later, in the account of Hall iV Harbour's [ilants, placed as a variety 

 of T. caniiuun, diih'ring from the type in its large and spreading usually much ciowded s|pikelets 

 and its long stout divergent awn. 15rewer's specimens show a teuileney to sport ; in one or two 

 cases the spike is branched below, and the spikelets are generally loose- liowered and siireading ; 

 sometimes the glumes have an occasional tooth near the tip and the lower palet is minutely 

 2-toothed at the beginning of the awn, varying in these resi)eets in the same spikelet. 



3. T. violaceum, Ilornem. Culms slen«ler, 1 to 2 feet high, and with the short 

 mostly convolulely-setaceous leaves and sheaths usually smooth : spike 1 to 3 inches 

 long, slender, strict and rigid ; spikelets 3 -r)-ll()W(!red, usually purple-tinged : glumes 

 Avith five strong rough nerves, short-pointed or brielly awned, nearly as long as the 

 llorets : lower i)alet strongly 5-nerved and rough above, with an awn from one-half 

 as long to as long as itself; upper palet as long as tlie h)Wer and pectinately ciliate.

Silver Mountain Trail, at 8-9,000 feet altitude, Brrnrr. Occurs in the mountains of New 

 England and New Yoi k, and in a few other eastern localities. The color, sometimes quite marked, 

 is often nearly or quite lacking. 



4. T, StrigOSUm, Le-ssing. Culms from 1 to 2 feet high, slender, very densely 

 tufted, with setaceous radical leaves half as tall, glaucous throughout ; culm leaves 3, 

 the uppermost 3 to 4 inches long, erect, reaching b(!yond the ba.^e of the spike, all 

 narrowly setaceou.sly (;onvolute, strigose-pubescent on the upper surface, below and 

 with the sheaths smooth or pubescent : sjiike 2 to G inches long, very slender ; spike- 

 lets 3-6-flowered, rather distant: glumes lanceolate, strongly 3 -5-nerved, some- 

 what acute, shorter than the florets, slightly .scabrous on the nerves : lower ]ialet 

 4 or 5 lines long, smooth below, 5-nerved near the apex and bearing a strong rough 

 divergent awn longer tlian itself; upper about erpial, retuse at ape.K and strongly 

 ciliate. — Linnaja, ix. 170; Griseb. in Ledeb. Fl. Itoss. iv. 339; AVatson, BoL King

Sierra County (Lemiaon) ; apparently more abundant in tlie mountains nf Nevada and Colorado ; 

 Asia Minor, etc. Our ])lant agrees snitieieutly with the deseiiption drawn from eastern sjieei- 

 mens to place it here. In our plant the strigose pubescence is eondned to the upper surface of the 

 leaves and entirely concealed by their convolution ; the glunu-s are shorter than described for the 

 eastern plant, and are often inequilateral, with jierves upon only one side of the midrib. Bo- 

 lander collected an abnormal form, with large spikelets, very dis'tant on a llexnose rliachis, and 

 the glumes awned or merely pointed in the same spike.
