1030 Excluded Species 



80. Panicum miliaceum L. Broomcorn Millet. This species has 

 been reported from Indiana but there is no evidence that it has become 

 established anywhere. 



Nat. of the Old World ; escaped in the northeastern states and occasion- 

 ally in other parts. 



81. Panicum scoparium Lam. I refer our reports of this species to 

 Panicum Scribnerianum. For a discussion of this subject see Deam's 

 "Grasses of Indiana," p. 335. 



Mass. to Ky., Mo., and Okla., southw. to Fla. and Tex. ; Cuba. 



82. Panicum Tuckermani Fern. (Rhodora 21: 112-114. 1919.) This 

 species is reported from Indiana in Hitchcock's Manual. His report is 

 probably based upon two of my specimens which he has so named. I have 

 studied the descriptions of this species as given by Hitchcock, Fernald, 

 Wiegand, and Victorin and, as I understand them, they do not agree. The 

 duplicate specimens of the numbers which I sent to Hitchcock seem to me 

 to be only forms of Panicum Gattingeri, hence I am excluding it from our 

 flora. This may be a valid species but I do not believe the specimens at 

 hand belong to it as it is described. 



Maine and Que. to Conn, and N. Y. ; Ind. and Wis. 



83. Cyperus compressus L. This species was reported from Jasper 

 County by Welch but the specimen is now referred to Cyperus dentatus 

 Torr. 



Coastal Plain from Pa. to Fla. and Tex. 



84. Cyperus ferax Richard. (Rhodora 37: 148-150. 1935.) (Cyperus 

 ferax Richard, in part, of Gray, Man., ed. 7.) Fernald & Griscom, in a 

 study of this species, show that it is restricted to the brackish and saline 

 shores from northern Massachusetts, southward to tropical America, and 

 on the Pacific coast from California southward, and that our interior 

 plants which formerly have been referred to this species should be re- 

 ferred to Cyperus ferruginescens Boeckl. 



85. Cyperus flavicomus Michx. This species was reported from Jef- 

 ferson County by Barnes and by Coulter. The range of this species does 

 not include Indiana and the report should be referred to some other species. 

 Our early authors should not be censured for making a few errors in de- 

 termination. It is surprising that they did not make more when it is 

 known that they had no authentic specimens for comparison and that the 

 manuals of their time gave short descriptions and these often applied 

 to aggregates. 



Va. to Fla. 



86. Cyperus hystricinus Fern. Reported from Jasper County by 

 Welch. No specimen so labeled can be found in the herbarium of DePauw 

 University, where a complete collection of Welch's Jasper County speci- 

 mens is deposited or elsewhere. 



N. J. to Ga.
