This species has been variously referred to Agropyron tenerum 

 Vasey, A. violaceum, Lange, and A. repens, Beauv. From the latter it 

 is distinguished at once by its c^espitose habit, absence of a rootstock, 

 leaves not auriculate at the base, strongly nerved outer glumes and 

 peculiar hispid rachilla of the spikelets. From A. violaceum it is dis- 

 tinguished by its much longer and broader leaves, usually green, rarely 

 purplish and longer spikes, and from A. tenerum by its much broader, 

 less rigid leaves and hispid rachilla. 



The plant described in Gray's Manual, ed. 6, 672. is the western 

 form which is doubtless true Agropyron violaceum, Lange, while the 

 variety mentioned " with longer usually pale narrow spikes and atten- 

 uate often long-awned glumes," is the plant here described as Agropy- 

 ron Novx-Anglise.

Under P. xanthophysum, form amplifolium, insert the following de- 

 scription by Professor F. Lamson-Scribner : 



Panicum xanthophysum forma amplifolium, Scribn. Culms stout ; 

 lower sheaths crowded, strongly striate and papillate-hirsute ; blades 

 firm, 10-20 mm. wide. Dry sandy soil, Burlington, Vt. L. R. Jones, 

 collector, August 31, 1893.

 psammophilum, Nash. 



Professor Scribner has re-examined the Vermont specimens of the 

 Panicum dichotomum group and the following additions and cor- 

 rections to the statements made on page 15, are based upon notes con- 

 tributed by him : 



P. Atlanticum. Erase this name as the plant doubtfully so referred 

 is a form of P. unciphyllum, Trin. See below.
