Excluded Species 1097 



the Gray Herbarium and two specimens in the herbarium of the New York 

 Botanical Garden and possibly others elsewhere. So far as I can learn this 

 species is known only from Rock Island. 



623. Solidago tenuifolia Pursh. Since this species, as now understood, 

 has a range to the east of Indiana, reports of it should be referred either 

 to Solidago media or to Solidago remota. 



N. S. to Fla. 



624. Solidago uliginosa Nutt. Reported mostly by our early authors 

 but I am referring all reports to Solidago uniligulata. As I understand this 

 species it does not come as far south as Indiana in our longitude. 



Newf. to the mts. of N. C., westw. to Mich, and Minn. 



625. Aster amethystinus Nutt. Amethyst Aster. This is an ambig- 

 uous aster with a wide range but of only local occurrence. It has been 

 found to be a hybrid of Aster novae-angliae and Aster multiflorus (of our 

 manuals) . See Rhodora 41 : 190-192. 1939. I have a specimen from Massa- 

 chusetts which is undoubtedly this species. I also have in my exchange 

 from other states, specimens so labeled which evidently belong to this 

 species. It was reported many years ago from Steuben County, by Brad- 

 ner, but I believe this record can safely be ignored. It was reported from 

 Lake County in 1930 by Peattie, who says "It has been collected rarely 

 near Clarke." I have not been able to see a specimen, and following the 

 rule of excluding all species unless I know of an authentic specimen, I 

 exclude it. 



Mass., N. Y., Pa., 111., Iowa, and Nebr. 



626. Aster angustus (Lindl.) T. & G. This is a western and northern 

 aster which is spreading eastward. According to Gray's Manual, ed. 7, it 

 has reached Chicago. Peattie reports it from the dune area but cites no 

 specimen. It seems that Peattie reported species for which he had no 

 verifying specimen and for that reason, I exclude it until I see or learn 

 of an authentic specimen that was found in Indiana. 



627. Aster divaricatus L. This species has been reported from Clark, 

 Monroe, Noble, and Porter Counties. It may occur in Indiana, but I 

 have not seen a specimen. Buhl (Amer. Midland Nat. 16: 252. 1935) re- 

 fers Peattie's report from Porter County to A. furcatus. 



Que. to Man., southw. to Ga. and Tenn. 



628. Aster imperialis M'Murtrie. (M'Murtrie. Sketches of Louisville 

 including a Florula Louisvillensis, p. 213. 1819.) This species w r as de- 

 scribed from a single specimen found by its author on the bank of Blue 

 River (probably on the boundary between Harrison and Crawford Coun- 

 ties). Apparently the description applies to some species of Erigeron. 

 Since the species is in doubt, and in the absence of a specimen, it is dropped. 



629. Aster lateriflorus var. glomerulus (T. & G.) Burgess. This I re- 

 gard as an ecological form of the species and place it in the synonomy of 

 the species. Reported from Porter County by Peattie.
