1026 Excluded Species 



46. Eragrostis hirsuta (Michx.) Nees. A robust specimen of Era- 

 grostis capillaris from Posey County was named Eragrostis hirsuta for 

 me and I reported it as such. I now refer it to Eragrostis capillaris. 



Md. to Mo., southw. to Fla. and e. Tex. 



47. Eragrostis mexicana (Hornem.) Link. Mexican Lovegrass. A 

 specimen of this species was found by Umbach many years ago in the 

 vicinity of Clarke, Lake County. It is his no. 3837, and I am considering it 

 as a waif since we have had no additional reports. 



Tex. to Ariz. ; introduced into Del. and Iowa. 



48. Eragrostis pilosa (L.) Beauv. India Lovegrass. This is a 

 European species which has escaped to all parts of the eastern United 

 States and which has been confused with our native species, Eragrostis 

 pectinacea. I have not seen a specimen from Indiana, and I believe all of 

 our reports should be referred to Eragrostis pectinacea. 



Nat. of Eu. ; Mass. to Colo., southw. to Fla. and Tex. ; southw. through 

 Mex. and W. I. to Argentina. 



49. Eragrostis poaeoides Beauv. (Eragrostis minor Host of Gray, 

 Man., ed. 7 and Eragrostis Eragrostis (L.) Karst. of Britton and Brown, 

 Illus. Flora, ed. 2.) This species has been reported several times by the 

 early authors when it was not separated from Eragrostis cilianensis. I 

 have seen no specimen, and I believe all reports should be referred to 

 Eragrostis cilianensis from which it is usually not distinguished. 



Nat. of Eu. ; Vt. to Iowa, southw. to Ga., Tex., Ariz., and Calif. 



50. Eragrostis trichodes (Nutt.) Nash. This is a western species that 

 has been reported, but I have seen no specimen. It will doubtless be 

 found on the sand dunes of the southwestern part of the state. 



111. to Nebr., southw. to Tex. 



51. Catabr6sa aquatica (L.) Beauv. J. C. Arthur, in his "Manual of 

 Rusts of the United States," page 150, reported this species as occurring 

 in Indiana. I have not investigated this report but I assume that there 

 has been an error in determination since the range of the plant is far 

 from Indiana. 



Newf., Lab. to Alberta, southw. to N. Dak., e. Oreg., and n. Ariz. 



52. Cynosurus cristatus L. In 1933 Madge McKee found this species 

 in a lawn at 656 North Eighth Street, Lafayette, Tippecanoe County; 

 it had no doubt been introduced in some lawn seed. 



Nat. of Eu. ; Newf. to Mich., southw. to Va., Wash., and Oreg. 



53. Agropyron caninum (L.) Beauv. This is a European species 

 which I believe our authors have confused with our native species, Agro- 

 pyron subsecundum. The glumes of the foreign species have 3 nerves in- 

 stead of 4-7 nerves. 



Nat. of Eu. ; found in ballast near Portland, Oreg. 



54. Aegilops cylIndrica Host. Jointed Goatgrass. A colony of this 

 grass was found in June 1938 by Chas. M. Ek along the Nickel Plate Rail-
