Further Notes upon Corema. 
By John H. Redfield, 
My notes (in Bulletin for September 1884) upon the localities 
of Corema Conradii have had the desired effect of eliciting from 
other contributors many new facts in regard to its distribution, 
especially in the more eastern portions of its geographical area. 
Among the more interesting of these notices is that of Mrs. Owen 
announcing its occurrence in the open sandy plains of Nantucket, 
where the conditions are such as. would lead us to expect it, and also 
that of Prof. Lawson relative to the varied conditions under which it 
appears in Nova Scotia. He has pointed out the fact that, when 
growing in sand or gravel, the plant becomes more gregarious, cover- 
ing continuously large areas, while upon rocks it is restricted to 
more isolated patches. Its manner of growth, in all the localities I 
have seen, accords with the observations of Prof. Lawson._ 
Early in July of this year, after some ineffectual search in Martha s 
Vineyard, I had an opportunity to see one or two of the localities in 
Nantucket. My examination was necessarily hasty, and probably I 
did not strike the most abundant one mentioned by Mrs. Owen. But 
I saw very numerous and extensive areas of the Corema between the 
old and new roads to Siaconsett, about four miles out. Its associates 
were Arctostaphylos Uva-ursi (which grows upon this island in greater 
profusion than I have seen it elsewhere), Hudsonia crtcotdes,_ and 
Comptonia, with some Myrica cerifera in the vicinity. The soil ap- 
peare'd to be purely silicious. . . 
Through Mrs. Haines of Bangor, I have received a specimen ot 
Corema collected this summer bv Mr. Robert Smith of Jersey City, 
at North Truro, Cape Cod, where it was associated with Hudsoma 
ericoidcs, "on the side of a hill near the foot of .which was a growth 
of scrub-pine." This may be the locality mentioned to me by Mr. 
Benjamin M. Watson, Jr. (Bulletin xi., 99.) _ , ■ , r 
In August, I climbed Mt. Beatty and Mt. Magunticook, which he 
just north of Camden, Me., and which I suppose are the eminences 
referred to by Prof. Chickering (Bulletin xi., 116.) I was not 
successful in finding his locality. The summit rocks there are of 
quartzite. much glaciated, and would afford a suitable siljcious soil. 
Much Finns Sirobus grows upon these hills, but I saw no / tnus ngida, 
the usual tree concomitant of Corema. There may Perhaps be some 
error in Prof. Chickering's reference to this locality. Blue Mountain 
which he names lies not back of Camden, but about 22 miles north- 
eastward, beyond Castine.
