sheaths striate, pubescent below, and 

 sparingly ciliate along the margins, the 

 basal ones shorter, the upper longer than 

 the internodes; ligule membranous, very- 

 short; leaf blade constricted at the base, 

 smooth on the back, scabrous above and 

 on the margins, 2 to 3 lines wide, linear 

 attenuate to the acute apex, the lower 

 culm leaves 6 to 9 inches, and the upper- 

 most 1 to 2 inches. Spike of 8 to 12 com- 

 pressed oblanceolate spikelets. Spikelets 

 6- to 7-flowered, 8 to 10 lines long, shorter 

 than the internodes of the rachis, which 

 Is scabrous on the margins; empty glumes 

 two-thirds as long as the spikelets, nearly 

 equal, linear, acute or acum.inate, 5-neiv- 

 ed, scarious on the margins; flowering 

 glume lanceolate, acute, 41/2 to 514 lines 

 long, flattened on the back below, promi- 

 nently 5-nerved above, and scabrous to- 

 ward the minutely 3-toothed awnless or 

 short-awned apex. Awn, when present, 

 straight, slender, 3 to 4 lines long. In- 

 ternodes of the rachilla 1 line long, mi- 

 nutely pubescent. Palea as long as the 

 glume, acute or obtuse. Represented in 

 the National Herbarium by specimens 

 collected by S. B. Parish in Waterman's 

 Canon, San Bernardino Mountains, Cali- 

 fornia, at an altitude of 3,000 feet, No. 2,054, 

 June 28, 18S8, and No. 2238, June 23, 1891. 

 This species apparently connects Agropy- 

 ron with Brachypodium. The habit is 

 similar to that of A. Arizonicum. It is 

 the only American species with pubescent 

 culm nodes."— Scribner & Smith, b 4, p 28 

 D-A agr (6F 1897).

 HIPPURIS VULGARIS L. 



"Springing from a perennial roo's-OCK, 

 with annual, simple, erect stems and 

 whorls of 6-12 cr more l-ner.ed linear 01 

 lanceolate leaves which are more or less 

 decayed (sphacelated) at the tips, and 10- 

 20 mm long by 1-3 mm broad. Stamens 

 with short, thick filaments and compara-

 hisce laterally. Fruit oval, or somewhat 

 4-sided, hollow in the interior, 2 or 3 mni 

 long, stigmas persistent. Common in 

 Arctic j^merica and Canada. It occurs al- 

 so in Moosrehead Lake, Man? (Porte ), 

 west to Oregon, and thence to California 

 (Parish) and New Mexico. Mr. Sa^ord 

 sends it from the Straits of Magella i, and 

 it is common in Europe and Central 

 Asia."— Morong, Torr hot cl b 18:231.
