The Flora of the Cayuga Lake Basin 69 



Mass. to Mich, and Kans., southw. to Fla., W. I., and Tex. ; naturalized northw. 

 Found also in Mex., Eu., and elsewhere. 



Of rather recent introduction in the Cayuga Lake Basin, where it was not known 

 at the time of publication of Dudley's Cayuga Flora. 



5. E. peregrina Wiegand. (See Rhodora 19:93, 1917, and 21: 133, 1919.) 

 Dry waste places, in gravelly soil and cinders ; rare. July 15-Aug. 



D., L. & W. yards, 1914; L. V. R. R. yards n. of station, 1914-1918; railroad tracks 

 of Central N. Y. Southern R. R., by Percy Field. [Also, Central N. Y. Southern 

 R. R. yards in Auburn, 1918, A /. E.] 



Known from but few stations in e. U. S., Germany, and Japan, and in all these 

 places a weed. Becoming more frequent in the Eastern States. Native land unknown. 



6. E. cilianensis (All.) Link. (See Rhodora 18:235. 1916. E. major of Cayuga 



Fl. E. megastachya of Gray's Man., ed. 7.) 



A weed in dry gravelly waste places and by roadsides, not in distinctly acid soils ; 

 frequent. July-Sept. 



Near Coy Glen (£>.) ; streets of Ithaca (D.) ; cemetery, University Ave., Ithaca; 

 various places on C. U. campus; near the " Nook" (D.) ; West Junius; and elsewhere. 



Nearly throughout the U. S. and s. Canada; commonest southw. Naturalized from 

 Eu. 



7. E. minor Host. 



In situations similar to those for the last-named species, or perhaps in less dry and 

 slightly richer soils ; locally common. July-Sept. 



Abundant on the railroad tracks and roadsides about Renwick ; C. U. campus ; 

 railroad yards, Cayuga. 



N. E. to Pa. and N. Y. Naturalized from Eu. 



Not known here at the time of publication of Dudley's Cayuga Flora. 



8. Diplachne Beauv. 



1. D. maritima Bicknell. (See Bui. Torr. Bot. Club 35 : 195. 1908. D. fascicn- 

 laris of Cayuga Fl. Lcptochloa fascicularis of Gray's Man., ed. 7. D. procum- 

 bens Nash.) 



Low ground around salt springs ; rare. July. 



"Montezuma, near the salt well, also in pasture, near Salt Cr." (D.\). 



Mass. southw. along the coast to Fla. and Tex., and from 111. southw. along the 

 Mississippi River. 



As treated by Hackel and others, this species is considered generically distinct 

 from Leptochloa and is placed in the Festuceae. An inspection of material of the 

 various species in each genus seems to support this view. 



9. Phragmites Trin. 

 1. P. communis Trin. Reed Grass. 



In the larger marshes, perhaps under the influence of salt or lime from the under- 

 lying strata; locally abundant. Sept. 10-Oct. 



Sparingly at Summit Marsh (D. !) ; " abu»dant throughout the Canoga, Cayuga 

 and Montezuma Marshes" (D. !) ; Crusoe Bog. 



N. S. to B. C, southw. to Fla. and Mex. ; common along the coast. Found also 

 in Eurasia. 



10. Dactylis L. 



1. D. GLOMERATA L. ORCHARD GRASS. 



Fields, roadsides, and the borders of woods, in rich soil ; common. June. 

 Often cultivated, and widely escaped. Native of Eu., now naturalized very gen- 

 erally in the U. S.
