490 General Notes. [ August, 
which was discovered by Mr. Jackson Dawson nine or ten years ago, was 
then the only one known in the United States or, indeed, on the continent. 
Up to this time the only contradiction to the current aphorism, “There 
are no heaths in America,” came ‘from Newfoundland, where Calluna 
was known to occur, although few botanists had ever seen specimens. 
It required some hardihood, as well as a clear conception of the causes 
which have ruled over the actual distribution of our species in former 
times, to pronounce that this Tewksbury patch of heath was indigenous. 
The discoveries, soon afterwards, in Nova Scotia and Cape Breton still 
left a wide hiatus. This was partially bridged over by the detection by 
Mr. Pickard, a Scotch gardener, of a similar very restricted station in 
Maine, on Cape Elizabeth, near Portland. We have now the satisfaction 
of recording a second station in Massachusetts, not far from the former 
one. Mr. James Mitchell, of Andover, is the present discoverer, aud 
. the station is in the western part of Andover, half a mile northeast of 
Haggett’s Pond, and five miles north of the Tewksbury station. Mr. 
Mitchell accidentally met with this patch last summer, when berrying, 
and, being a Scotchman, recognized it, took home a sprig of it, and at a 
subsequent visit grubbed up one or two small plants, which a neighbor 
still has in cultivation. A fresh branch taken by him from the wild 
plants this summer is now before me. It proves to be of the green and 
smoothish variety of Calluna, precisely like the Tewksbury plant. Small 
as the new patch is said .to be, “ it will serve” to confirm the opinion 
long ago expressed; for a second station greatly diminishes the very small 
chance of its having been casually or in any way introduced through alt 
man agency. It should also be noted that this station, as I am inform 
by the Rev. Mr. Wright, is near by an extensive glacial moraine which 
traverses that district, and which he has traced for a great distance 
northward. — Asa Gray. 
HETEROMORPHISM IN Epig.®a.— The May-flower, being more largely 
gathered and brought under our notice than any other wild blossom ~- 
at least in the Atlantic States — should be well known in all the details 
of structure. But it hardly is so. The structure of its stigma a 
first well described in the fifth edition of my Manual of the Botany © 
the Northern United States, and the likeness to Pyrola sugge aon f 
suppose that this likeness is really one of relationship, but not of a a 
degree, as most other points of similarity are wanting. F rom the di si 
ence in the stigmas of different flowers, I was disposed to think that , 
five lobes lengthened and protruded with age, in the manner of EY 
but this does not prove to be the case. In all cases, however; t re pare 
of the style is as it were hollowed out or extended into a ring, with sal 
crenate border, to the inner face of which the five stigmas arè adn ‘ 
each before one of the small teeth or lobes, and extending poe 
slightly beyond it, but remaining short and erect, sometimes much 
yond and radiately expanded. i :
