ing and mounting; and makes perfect and enduring specimens. As 

 it was only recently discovered this side of the border, in Maine, it 

 has not been admitted to the Manual. 



Perhaps I ought to express the hope that my readers will not 

 assume, in view of the excessive attention thus far lavished here upon 

 the mere weeds, that the Island was altogether " an unweeded gar- 

 den, that grows to seed." There was many a little untamed bog, 

 or copse, or shore, which well repaid search for the plants which 

 belong there ; the shy natives in their own proper homes ; and my 

 collections included many such species. Brief mention of two only 

 of these, which had also the charm of jiovelty, must suffice. 



The Dwarf Mistletoe (Areeuthobmm pusillum) has become well 

 known only within comparatively few years, and though it is proba- 

 bly widely distributed, yet it is still sufficiently rare or local to com- 

 pel attention to each newly discovered station. So I was pleased 

 and perhaps pleasantly excited when I discovered the tiny parasite 

 growing in abundance on the Black Spruce, in a sphagnum bog just 

 behind the broad sandy beach at Tracadie. Its history, appearance, 

 habits and distribution were so fully discussed in this Journal (Vol. 

 II, pp. 1 to 11, and p. 221,) that but little beyond this record of its 

 occurrence here need be given. It should be said however that, 

 while the White Spruce and the Larch were both abundant in the 

 neighborhood, yet I did not find the Mistletoe upon them. I was 

 also impressed with the almost constant association, upon the same 

 tree, of the Mistletoe with Peridermium abietitwm, the fungus referred 

 to by Prof. Arthur (Rhodora, II, 223) ; and the yellow sprays of 

 the spruce, with leaves infested and discolored by the fungus, were 

 the surest guides to the colonies of the flowering parasite upon 

 the branches. I find no definite record of the occurrence anywhere 

 in Canada of the Dwarf Mistletoe. 



The second native and notable plant was a Tillaea, which I found 

 in the wet sandy margin of Campbell's Pond, which is separated 

 from the ocean by the same broad beach at Tracadie. Though the 

 station was far north of its known range, it was of course assumed to 

 be Tillaea simplex, and it was only after careful examination since my 

 return, that Mr. Fernald identified it with T. Va/lla/itii, Willd., of 

 Africa and Central Europe. The little plant, less than an inch high, 

 grows in moss-like tufts like its congener T. aguatica, L. (T. simplex, 

 Nutt.), from which it differs principally in the elongated pedicels of
