20 Rhodora [JANUARY 
Now that we know on the south side of Cape Cod a unique relative 
of Juncus maritimus and J. Roemerianus it seems not impossible that 
Pursh really saw some member of this group on the New Jersey coast, 
although the station may now be obliterated. The stations of J. 
maritimus on Coney Island and of J. pervetus on Cape Cod are both so 
very limited that only a very mild degree of “improvement” would 
quickly obliterate the former from the flora of North America while 
the latter would as quickly become an extinct species. 
Gray HERBARIUM. 
A Form OF SOLIDAGO SEMPERVIRENS WITH Warre Rays. — Late in 
the season of 1915 there were brought to me two or three plants of 
the seaside golden rod the rays of which were creamy white, practically 
the same color as in Solidago bicolor. As these were gathered quite 
near the water at high tide, it seemed to me more than likely that 
the whiteness was the result of the spray dashing over the plants, 
although it is true that I did not find signs of it on the leaves. 
This year (1916) I had an opportunity to examine the plants where 
they grow. They are at Isle au Haut, Maine. The particular colony 
where I have found the white-rayed form is composed of two hundred 
to two hundred and fifty plants, and the plants with the white rays 
grow mostly at one end of the patch, but they are scattered amongst 
the common yellow form in a way that precludes the possibility of 
spray having anything to do with the whiteness. Perhaps ten per 
cent of all the plants in this colony show the white rays. 
This may be common elsewhere, but it has never happened to come 
to my notice. I should be glad to hear whether others have found the 
same form.— NATHANIEL T. Kipper, Milton, Massachusetts.
