1921 J Fernald, — Expedition to Nova Scotia 151 



The bottom of the lake had a fine development of Subularia aqua- 

 tica but the most amazing sight of the day was the acres and acres 

 of the southern Solidago Elliotii, forming solid thickets nearly 2 m. 

 high in the spruce and red maple (often Acer rubrum, var. tridens) 

 swamp. It was, indeed, a strange experience and one we should 

 hardly expect even in the southern coastal plain, to break our way 

 through the tall stems of this southern goldenrod, much as we had 

 sometimes done on Maine bottomlands through the overtopping 

 masses of Ostrich Fern. When reporting the seeming absence (p. 143) 

 of the characteristically Canadian goldenrod, Solidago canadensis, 

 from much of southwestern Nova Scotia, reference was made to an 

 immature plant which there takes its place. This, needless to say, 

 is S. Ellitttii, which from mid-August through September colors the 

 spruce swamps and boggy clearings. Occasionally, too, in the Barr- 

 ington swamp there were clumps of Solidago rugosa, var. sphagno- 

 phila, described from southeastern Connecticut, but now known to 

 be commcn in southeastern Massachusetts and south to New Jersey. 



The nett morning, most happily, brought Dr. and Mrs. Graves 

 and with them the news that, although he had been unable to get 

 passage on the boat with them, Bissell would be back next morning; 

 and after getting the presses in order, we started out for a short 

 afternoon walk, Long and Linder going to Sand Beach where they got 

 Polygonum allocarpum Blake, 1 and found that the Elyvius virginicus 

 of the barrier beach was all var. hirsutiglumis. Dr. and Mrs. Graves 

 and I followed the railroad southeast beyond Yarmouth, getting 

 into such masses of Ilabenaria psycodes as we had never imagined, 

 thousands of brilliant plumes almost crowding each other in the 

 boggy swales. Botrychium dissectum and var. obliquum were very 

 abundant and here, as elsewhere in Nova Scotia and the eastern 

 states, shew such a connecting series as clearly to indicate that they 

 are mere I'orms of the same plant, and since the name B. dissectum 

 Spreng. has priority of six years over B. obliquum Muhl. it is necessary 

 to call the latter B. dissectum, forma obliquum.- Sicglingia abounded 



'Rhodorji, xix. 234 (1917).
