The parts in their natural place are the outer sac, the lower sepal, 
the stigma and the two pollinia. The lower sepal i is broader than 
is usual, the stigma deeply two-lobed and twice the ordinary 
width, The right-hand pollen-mass is doubled, the third one 
standing at the apex of the angle made by the two ‘barren stamens. 
These stamens are of the ordinary size, and face each other at an 
remaining space. There are a sepal and two petals on the upper 
left side, and the same on the upper right, each part of the usual 
size. The natural flower is the left one to which the outer sac 
belongs. Itsright-hand petal is nearly vertical, where the upper se- 
pal naturally stands. The left petal of the right-hand flower stands 
directly behind this, and has grown by one edge to the edge of 
the upper or invotucral leaf, which in turn is grown by the re- 
. mainder of the same margin to the ovary, so as to be adherent 
all the way from the base of the ovary to the top of the petal. 
The ovary is enlarged, one-celled, with four parietal placente ; 
some of the placentz are uncommonly broad, and are probably ` 
doubled, though so woe connected as not to be distinguished. 
One sac is contained in the other, but entirely free, and readily 
drawn out. . The inner sac Tia to the right- hand flower, its 
claw being a little to the left of that of the outer. Though con- 
tained in the outer, it is really larger when inflated, being crum- 
pled as it is packed away. The flowers are large, the sacs being 
two inches long. 
From the position of the parts, which were carefully compared 
with fresh specimens of the single flower, itis probable that this 
monstrosity arose from two buds, starting from the same point of 
the stem, and adhering by their inner faces, those parts only be- 
ing doubled in reality, for which room for development was 
found, the doubling of the rest being disguised in the enlarged 
parts that represented them. ost of the specimens I have ex- 
Lake Co., Ind: have since been told that it is not unusual to 
find these double eb eis Lady’s Slippers, though it is the first 
that has come un my observation, or that of any of my bo- 
tanical friends to aa I have mentioned it.—£. F. Hill. 
A New VARIETY oF CAMPANULA ROTUNDIFOLIA L.—While jak se 
lecting plants in the northern part of Michigan the past summer, _ 
I discovered a form of this plant that I do not find mentioned. 
It differs from the ordinary forms in being densely pubescent, or 
hoary with short, reflexed hairs, at least on the lower part of the- 
stem and leaves, some plants being smooth or somewhat so above.
