' pearance than the appearance of those I havesought. I have looked 
in vain for many plants which would be likely to be found here, but 
have failed to find them, though I have been rewarded by discover- 
ing species new to me and often of more interest than those I sought. 
While looking for plants at River Head I found, very unexpect- 
edly, Botrychium simplex, Hitch. I find it every year in the same 
place, though never anywhere else. I think it is not so rare as is 
generally thought ; being small and green, it is easily overlooked. 
Mr. Young and myself found Rhyncospora nitens, Gray, very plenty 
at Long Pond, near here, in 1872. We have never been able to find 
it since. We found at the same place, the same year, Polygonum 
Carey, Olney, very plenty. The next year we found a few specimens. 
Since then we have not observed a sign of a plant. I found once 
a single specimen of Aster Novae Angliae, L., at Long Pond.’ I 
gathered the cluster of flowers, but was particular to leave the root. 
I have never been able to find it again. Long Pond is the only 
locality where I can find Galactia mollis, Mx. I found Utricularia - 
gibba, L., there for a year or two, but don’t find it now. In 1872 I 
found two or three plants of U. resupinata, Greene, growing on a 
floating mass of Nymphzea roots and mud. The same year I found 
it at Deep Pond, about a mile from Long Pond. The little purple — 
flowers were so thick on a square rod of ground that they showed 
plainly at some distance. I have searched eagerly for it in that 
spot every year since, but in vain. I found, at Deep Pond, the same 
year, Oldenlandia glomerata, Mx. ; that, too, has disappeared. Pota- 
mogeton Robbinsit, Oakes, grows in Deep Pond. I have only 
examined fragments which I have picked up along the shore. There 
is no boat in the pond, and it is very deep, in some places 4o feet. 
I used to find Reseda luteola, L., and Verbena officinalis, L., in the 
streets at Mt. Sinai, but they have both been destroyed. Mentha 
aquatica, I.., var. crispa, Benth., has too strong a hold there to be 
easily destroyed. I have found one plant, each of Asclepias varie- 
gata, L., and Asclepias phytolaccoides, Pursh, here, but they have 
both been destroyed. Mr. Young found the latter at Northville. 
A large patch of A. purpurascens, L., grows near Deep Pond. I 
never saw it flower but once, and then it did not mature any fruit. 
Chenopodium glaucun, L., is a weed in a garden near the Sound. 
Celtis occidentalis, L., is very plenty at Stony Brook, on the farm of 
Mr. Thos H. Hadaway. I find Betula papyracea, Ait., about here. 
It flowers before the leaves expand, while &. alba, L., var. populifolia, 
Spach, does not flower till the leaves are half grown. I have never 
been able to find more than one specimen of the typical form of 
Juniperus communis, L. .The var. depressa, Torr., is very comtnon. 
I occasionally find M/atricaria tnodora, L., when I am mowing. As 
it is cut before the seed ripen it is not likely to incréase very fast. 
I went to Babylon last spring to collect Zinnaea borealis, Gronov. 
I followed closely the directions where to find it, given in the 
Butierin by Mr. Merriam. I searched long and _ diligently, 
but failed. I feel quite sure it is entirely destroyed, for a fire had 
‘passed over the spot a year or two previous to my search, and de- 
stroyed everything above ground. As the roots do not grow very
