Excluded Species 1027 



road in Kokomo, Howard County. The colony was one to one and one half 

 feet wide and about 80 feet long, located between the main track and a 

 siding about midway between Lock and Ohio Streets. Undoubtedly a rail- 

 road migrant. 



Introduced from Europe ; Mo., Kans., Okla., Colo., and N. Mex. 



55. Hordeum vulgare L. Barley. Barley was formerly a staple crop 

 in Indiana, but it is now rarely grown. It is an annual and sometimes 

 appears spontaneously in fields and waste places, but it will not persist. 

 There are no reports for the state, and it is given in the key in order to 

 prevent errors in determination. 



The origin of our cultivated barleys is lost in antiquity. 



56. Lolium temulentum L. Darnel. Wilson reported this species as 

 found on the streets of Lafayette. There is no specimen. 



Nat. of Eu. ; common on the Pacific coast and occasional throughout the 

 eastern U. S. 



57. Trisetum pennsylvanicum (L.) Beauv. This species was reported 

 from Clark County by Baird & Taylor. Since there is no specimen, the 

 report must be ignored. 



Mass. to Ohio, southw. on the Coastal Plain to Fla. and westw. to Tenn. 



58. Deschampsia flexuosa (L.) Trin. Reported from Clark County by 

 Baird & Taylor. Since there is no confirming specimen, this species is 

 dropped from our flora. 



Greenland to Alaska, southw. to N. C, Mich., Wis., and Okla. ; also in 

 Eurasia. 



59. Aira praecox L. This grass was reported from "southern Indiana" 

 by Lapham (Trans. Wisconsin Agric. Soc. 3: 469. 1854). There is no 

 subsequent record and I have not seen a specimen. 



Coastal species from N. J. to Va. and Vancouver to Calif. 



60. Avena fatua L. Wild Oat. This grass was reported by C. P. 

 Smith (Proc. Indiana Acad. Sci. 1905: 301. 1906). He writes: "About a 

 half dozen plants were found along the Monon Railroad at the State Fair 

 Grounds." I searched this area for two different years and I could not 

 find it. I am assuming that it was a migrant and that it has not established 

 itself. 



Nat. of Eu. ; Maine to Pa., Mo., and westw. ; common on the Pacific coast. 



61. Avena sativa L. Oat. This is our cultivated oat which is an 

 annual and is often found as a volunteer but it does not maintain itself. 



62. Danthonia compressa Austin. This species was included in Troop's 

 "Grasses of Indiana." Troop wrote me that the specimen came from La- 

 grange County. Since there is no specimen, it is excluded. 



N. S. to Que., southw. to mts. of N. C. 



63. Calamagrostis cinnoides (Muhl.) Bart. My specimen no. 9014 

 was named this species for me by an authority and I reported it as new to
