sometimes intergradient or that they occasionally hybridize. 

 Nevertheless it would be little doubted, I think, by anyone coming 

 to know S. aestivalis, that it was essentially distinct, and long 

 ago it became to me an authentic and, from its early time of 

 flowering, a particularly interesting member of the golden-rod 

 group. Its smooth and purple striate-angled stem is notably at 

 contrast with the more terete and papillate-hirsute or villous 

 stem of normal S. rugosa, although its smoothness may not be 

 taken as a strictly determining character, for S. rugosa occasionally 

 passes into glabrate forms; but such divergent plants, as I have 

 met with them on Long Island, are obviously only local variations 

 from the type not at all to be correlated with the normally glabrous 

 stemmed S. aestivalis. In view of such variations, however, the 

 characters of the latter might be given less weight did not its 

 definitely earher flowering period, both in its beginning and 

 ending, imply a very pronounced remove from identity with the 

 broadly similar S. rugosa. 

 Solidago Elliottii T. & G. 



Common in low grounds. Some flowering panicles September 

 10, 1907, but not yet generally in bloom at that time. 

 Solidago uniligulata (DC.) Porter. 



Not infrequent In Sphagnum bogs on the eastern side of the 

 island. Not in flower up to the middle of August, 1906; in full 

 bloom September 5, 1904. 



Note. — Solidago neglecta T. & G. is named among the golden- 

 rods of Mrs. Owen's catalogue, and it may well be a rare plant of 

 Nantucket, but no evidence appears that it has ever been collected 

 there. It is quite possible to mistake for it large examples of S. 

 uniligulata or even forms of S. Elliottii. 

 * Solidago juncea Ait. 



This common eastern golden-rod seems to be all but absent 

 from Nantucket, only a solitary cluster having been discovered 

 there. This grew on a dry slope near the Wauwinet road about 

 half a mile west of Pulling Mill Creek. On August 16, 1906, its 

 several vigorous stems bore panicles of close green buds, and on 

 September 11 , 1 907 , it was in full bloom. The plant was perfectly
