Dear Sir: 



The ocirpus collected by Mr. Churchill in Lincoln County, 



Maine is S. oeoidentalis . I think Pernald has found an older 



name fc^ M U hlenberg>f or this. As we do not index anything 



other then grasses, I can not at this moment put my hands on 



the reference. I think it was S. acutus but I am not sure. 



I had some notes on the specimens I examined in Muhlenberg's 



herbarium the last of 1903. I had had it in mind that S. 



acutus might be one of the species of Scirpus. I can not find 



my notes. As I remember it the culm was strongly spotted as 



is your specimen, due to some fungus disease. This spotting is 



common to the three species. 3 do not remember now why I 



decided against it but 1 have a faint recollection that there wa 



no inflorescence left. You see how completely I have "gone to 



grass". I have not kept track of the literature of anything 

 else and I have mislaid the notes I did have, or else they have 

 gone to the University of 111 inois .with -my specimens. I shall 

 be glad to look over your group of / r2fo t frt^Mfm#is if you ' 

 think from the foregoing that I have sense enough to identify 

 them. I am returning your specimen of occiden talis. 



Very truly yours, 



Act:"n£ Systematic Agrostologist .
