rather common in the northern half of New England, and the fact that 
it has been so long overlooked is doubtless due on the one hand to its 
small size, and the other to its peculiar mode of growth upon branches 
of trees and often out of reach. At Hanover, New Hampshire, it was 
discovered by Professor Jesup, and grew upon the black or swamp 
spruce (Picea nigra, Link). Knowing the plant well at that station, 
some ten years ago, the writer has since spent much time in searching 
for it in Vermont, and was finally rewarded, May 6, 1899, by finding 
a new station at Pittsford, Rutland county. It was there growing on 
the black spruce in a small swamp, which had been searched several 
times before. 
In June the writer found the Arceuthobium again on Bald Moun- 
tain, Mendon, at about 2,200 feet altitude, and in this case upon the 
red spruce (P. ruéra, Link). 
Prof. L. R. Jones’ interesting discovery of the species at Alburgh, 
Vermont, on the black spruce, and later upon the tamarack (Larix 
Americana, Michx), is described in his article published above. 
President E. Brainerd has since found the Arceuthobium on the 
black spruce at Ripton, Vermont, and Prof. C. E. Peck tells me that 
it has been sent to him from the Adirondacks this fall on the branches 
of the white spruce (P. alba, Link). Although it has thus been ob- 
served upon no less than four species, the writer believes that it occurs 
chiefly on the black spruce. —WitLtarp W. Ecciesron, Rutland,

ARCEUTHOBIUM PUSILLUM IN THE Sr. JOHN AND Sr. LAWRENCE 
VALLEYS. — Late in September last, while crossing a low spruce swamp 
near Fort Kent in northern Aroostook county, Maine, the recollection 
of Dr. von Schrenk's interesting discovery of the dwarf mistletoe in the 
southern part of the state occurred to me, and I thought: **Why 
shouldn't I find Arceuthobium, too?" Instantly, upon looking up, I 
saw a sickly black spruce loaded with the small fruiting parasite. The 
plant covered many of the small black spruces; but though the white 
spruces, firs and hackmatacks were carefully examined, none of them 
seemed to harbor the mistletoe. Nor was any strong tendency to 
Hexenbesen seen in the affected trees, such as has been noted in other 
regions by Dr. von Schrenk and Professor Jones. The only marked 
effect of the parasite upon the host-trees was a tendency to produce 
unusually slender branchlets and yellowish foliage.
