il, Notes by €. F. Austin—On Nov. 4th, at about noon, the day being 
a little blustering and cool, but clear—the thermometer certainly © 
above the freezing point—I found on the stems ofCunila Mariana, L., - 
close to the ground, flat and solid crystals of ice or frost, about } of 
an inch in thickness and about 2 inches square, somewhat bent or 
curled, translucent, and striated at right angles to the stem of the 
plant. The plants were growing on the west side of a slate ridge. 
The ground was not frozen, nor was there any ice in a pond hole 
near by. I do not recollect seeing any thing of the kind before, yet 
have heard of the same thing occurring with Helianthemum. The 
frost crystals, one on each plant, were not attached to the roots but © 
to the stem, and extended about 2 inches above the ground. 
Is it generally known among botanists that,when here and there a — 
Hemlock tree is cut from a grove where they stand close together, 
the stumps retain their vitality for many years? I know of a 
number which have continued to live at least 10—15 years. They 
never sprout! but continue to grow in diameter! This is caused, — 
of course, by the natural “grafting ” of the roots. 
I have found isolated Sassafras roots in damp clayey soil when 
the stump was entirely gone ; yet the roots possessed all the fresh- - 
ness of those from living trees! .

The Rev. S. W. Knipe, of Delaware Water-gap, Pa., has described 
to me a Pogonia found there by himself which must be P. affinis. He 
says he found only a single specimen, which he gave away, but thinks 
he can recover. : 
Negundo aceroides, Moench, grows along the Hackensack river, at the 
flats, about half a mile west of Closter.—Genm rivale, L., occurs on the 
meadows between Tappan and Piermont, a few rods east of the R. R. 
f, strietum, Ait., occurs at Closter. Closter, Nov. 14th. 
72, New Mistletoe.—About the 20th of September last we received 
from Miss L. A. Millington, Glens Falls, “a few specimens of a pa- 
rasitic plant ’’ that she had found growing on Abies nigra, Poir. : She 
wrote: “TI believe it to be a mistletoe. I found the first specimen 
on a small tree in the edge of a cold peat bog in Warrensburg, 
Warren Co., N. Y. In a few days I found more in a similar situation — 
in Elizabethtown, Essex Co., N. Y. Later I found it half way up 
the north side of a high mountain. All these places would seem to 
indicate a higher latitude than even Northern New York as the pos- 
sible habitat of the plant. In
