glumes papillate-ftilose witli ratlier stiff spreading hairs like those of the sheaths, 

 only somewhat longer; first glume broadly ovate, subacute, 3-nerved, one-third 

 to one-half as long as the second; second glume a little longer than the fourth, 

 rounded, obtuse, 7- to 9-nerved; third glume similar to the second, 9-nerved, with 

 a subhyaline palea nearly as long as itself, and usually inclosing a staminate 

 flower; fourth or fruiting glume smooth and shining, ol>tuse. marked with a 

 transverse fold or crease on the back, near the base. The panicle branches 

 become strict with age. 



Missouri, Iowa, Minnesota, Sotith Dakota, Nebraska. The t^^pe specimens

 in the National Herbarium, marked "Stevens Pacific Railroad Expedition, 5

As in several species of the group to which this belongs, there is a smooth 

 ring just below the nodes; below this the culms are very strongly scabroiis. 

 This species may bo distinguished from ranicum paucij'orum Ell., by its sca- 

 brous culms, not, as in that species, more or less pubescent, by having the 

 sheaths, leaves, and spikelets papillate-pilose; l)y its broader leaves and fewer- 

 flowered and more simple panicles, ranicum scoparlum Lara., as understood by 

 the writer, is a much stouter plant with hairy culms, bearded nodes, and leaves 

 softly iiubescent beneath, ranicum serihneriatium Nash, differs from Panicum 

 leihrrf/ii in having pubescent culms and more broadly ovate, glabrous, or very 

 minutely pubescent spikelets, the first glume of which is much shorter and 

 broader in proportion to its length. 

 Elynius brownii Scribu. & J. G. Smith, sp. nov. (Plate IV). {Ehjmus mollia R. 

 Br., Richardson in Franklin Narr., First Voy., p. 732 [1823], notTrin.) A some- 

 what rigid, but rather slender, erect perennial 5 to 9 dm. high, with short cau- 

 line leaves and densely flowered spikes 4 to 10 cm. long. Rootstock creeping. 

 Culms smooth, occasionally glaucous, and often slightly pubescent just below 

 the nodes; sheaiths striate, smooth; ligule very short, hardly 0.5 mm. long; leaf 

 Idades rather rigid, those of the innovations erect, 10 to 18 cm. long, 2 to 5 mm. 

 wide, scabrous ou the margins and nerves beneath, smooth above, very acute 

 and somewhat pungent-pointed; cauline leaves erect or ascending, 5 to 12 cm. 

 long, 4 to 8 mm. wide, very acute. Spikelets 3- to 6 flowered, 10 to 15 mm. long; 

 outer glumes linear-subulate from the base, short awnpointed, nearly as long as 

 or much shorter than the spikelets, scabrous or minutely pubescent toward 

 the base ; flowering glumes rounded on the back, densely ])ubescent or subvillous, 

 short awnpointed; first flowering glnnie-8 to 10mm. long; awns2 to4 mmlong; 

 palea uealy as long as the glume, 2-toothed, flnely ciliate on the keels above. 



Black Hillsof South Dakota-, British Columbia, and northward to Alaska. This 

 species is represented in the National Herbarium by specimens collected by Prof. 

 John Macoun, Bow River Pass, No. 107, September 13, 1879, also on the Sas- 

 katchewan Plains, No. 72, August 22, 1872; George W. Dawson, Dease Lake, lat. 

 58-, No. 103, June 23, 1887; Mr. James JIacoun, Kicking Horse Lake, British 

 Columbia, No. 43, August 16, 1890, altitude 5,000 feet and gravelly banks, Severn 

 River, Keewatin, July 29, 1886; 1178, P. A. Rydberg, June, 1892, Elk Canyon, 

 South Dakota; William M. Canby, Rocky Mountains, near Banft', Canada, .July 

 19, 1895. It is from this specimen that the plate illustratiug this species has 

 been drawn. English River, Saskatchewan; there is no further data attached 

 to this specimen.
