and in order the better to examine the ovary,

search I found the fruit, and, at last, one withered and dried bell 
which had not fallen. There was no longer a doubt as to this plant 
at least ; and, in the study I gave it there in the woods, it was easy 
to see what had occasioned it as to the specimen from Babylon. 
That consisted of the ends of. the summer runners only. I com- 
pared the plants on my return, and was fully convinced there could 
be no mistake. : 
I determined, therefore, to go to Babylon and see if I could find 
the plant, knowing nearly the locality in which I had found it 
three years ago. I went yesterday. The locality was considerably 
changed by the cutting away of the woods along the rail-road 
(South Side R. R.). I hunted for three hours the place over ; in 
the wood and out of it; around the stumps, under the brush and 
bushes, in the sun and in the shade. When I failed to find it, I took 
a new departure” where it seemed to have been, with no better 
success. I found plenty of Arctostaphylos Uva-ursi, Chimaphila um- 
bellata and C. maculata, Gaultheria procumbens, and Cypripedium 
acaule—but no Linnwa. I had at length about abandoned all hope 
of it, and concluded that it had died out with the cutting away of 
the woods, when I struck upon a few scattered plants. You may 
imagine my satisfaction! Down on my knees I went, and searched 
for the fruit like a miner for nuggets. Istruck upon the little forked 
scapes—but no fruit. I soon, however, traced it to the bed where it 
has taken possession of the ground, like Nepeta Glechoma, almost to 
the exclusion of all other plants. It covers a space 50 feet square, and, 
of course, there I found the fruit, and, at last, under some bushes, 
in the shade, one little scape with its two beautiful, blushing bells, — 
fresh and fragant, rewarded my seare 
_ I mention this, not only because I think you may feel a personal 
interest in the finding, but as showing how very local a plant may 
be, for Dr. Torrey thinks it has never been sven elsewhere on the is- 
land, and even in the New Durham swamp it is supposed to have 
been placed by Michaux. It gives hope, also, that we may yet find 
Corema Conradii, Clitoria Mariana, and some other plants which 
were long ago reported, but have not since been found on the is- 
land. They will be met with only by long search, or be come upon 
by accident. Knowing, as I thought, just where to find this, I 
hunted three hours for it, and was about giving up the search, when 
I fell upon it. 
It is about 70 feet north of the rail-road and 900 feet east of the
