A. spicatum (Pursh) Rydberg must include the following: 



(Piper Fl. Wash. 146 credits this to S & S. 1. c S3 erroneously, 

 the plant they describe is A occidental Scr. which is A Smithii 

 Rydberg. It is true at the close they state it is Festuca spicata 

 Pursh but their description differs and must take precedence. The 

 proper citation is A. spicatum (Pursh) Rydhenr rl. M«»nt h:1) 



Agropyron spicatum var. Arizonicum (S. & S. Rev. Agropy- 

 ron 27 as species) n. var. This includes A. Parisii S. & S. 



Agropyron spicatum var Pringlei (S. & S. 1. c. 31 as*A. Gme- 

 lini var.). I have a complete line of intergrades between all these 

 forms. 



Agropyron tenerum var. pseudorepens (S. & S. 1. c. 34 as 

 species). 



A. tenerum, as Hitchcock has shown, includes pseudorepens, 

 but this is a well /narked form growing in alkaline p'aces. The 

 original A. tenerum, of which I have ample material, was un- 

 doubtedly material of the second year from: seed started in the 

 fall ( Vasey describes it as a seemingly annual) growing in sweet 

 and good soil where it almost never stools, or the rootstocks are 

 very short or hardly noticeable. In alkaline soil it stools out and 

 produces copious runners. This is the tendency with most grasses, 

 though we would expect the reverse a* the effect of Rjilta on veg- 

 etative processes.

Bromus eximius (Shea') P»per Fl. Was •. 143 exhibits the 

 beauty of the botiuical buuco g&tae itte up el to b». worked on 

 botanists by the Brit toman system which the world b >taniets have 

 rejected. The system, like the Irishman's turtle with its head cut 

 off and still wriggling its tail i< dead but the tail portion in the 

 person of the man who forced it on the Department of Agricul- 

 ture is not sensible of it and compel* better men to use it in< pub- 

 lications of his Division. It is the belief of some geologists that 

 the Silurian age was not contemporaneous throughout the world 

 and some things in the Department of Agriculture squint that 

 way, but the writer believes it is a cise of arrested development. 

 Shear described R. vularis and refers it to B. purgans var. vulga- 

 ris Hooker. Piper concludes that it is different and because of the 

 previous varietal name changes it and all its varieties. To make it
