Habenaria hyperborea R . Br. 
The great variability of this species is recognized in the New York 
Flora, but no effort seems to have been made to classify the varieties. 
In the marshes and cedar swamps about Jordanville, three well 
marked forms occur. 
In one the plants are two or three feet high, with a stem six to ten 
lines thick, with broad leaves and a dense spike of spreading flowers. 
This is the largest and stoutest form. 
In another the plants are generally about a foot high, with a rather 
slender stem and narrow leaves, but with a dense spike of spreading 
flowers. 
In the third form the plants are eight to twelve inches high, the 
stem slender, the leaves narrow and the spike loose and slender, with 
erect or appressed flowers. 
Corallorhiza multiflora Nutt. 
A variety of this species has occurred in woods at Menands, Albany 
county, in which nearly the whole plant has a pale yellow color, the 
lip of the flower being white and unspotted. This is such a wide de¬ 
parture from the ordinary form that I have labeled our specimens 
Corallorhiza multiflora flavida. 
Cyperus esculentus L. 
The yellow nut grass sometimes penetrates the tubers of the potato 
by its sharp pointed rootstocks and develops its tubers in the tubers 
of the host. Specimens of this kind were brought to me by Mr. Van 
DeLoo, of the State Museum. One of the invading tubers was 
planted and it developed into a fine specimen of Cyperus esculentus. 
Carex castanea Wahl. 
This rare and interesting sedge still lingers in small quantity under 
the hemlocks on the eastern shore of Cedar lake, in the southern part 
of Herkimer county. Its first discovery in this country was made 
here by Professor Gray more than sixty years ago. At the time of 
my visit to this place men were busy cutting the hemlock trees and
