Atlantic to the great plains, but not to the mountains beyond. JV. 
Labrusca is our most local species, being confined to the Alleghany 
Mountains and the region between them and the Atlantic, unknown 
in the Mississippi Valley or beyond. Whatever has been called so 
there, or in Louisiana or Texas, is a large and downy leaved form 
of aestivalis, always readily distinguished by its “‘ intermittent ” ten- 
drils, while Zaérusca has more or less “ continuous ”’ tendrils. 
Will local botanists assist me to more accurately define the geo- 
graphical limits of our species of Vitis? And may I request them 
to collect fertile flowers as well as sterile, the only ones found in 
most herbaria ?

§ 240. Botrychium simplex, Hitch, in Mass.—I have received 
from Mr. E. S. Wheeler of Berlin, Mass., a specimen that proves to 
be good B. simplex Hitch. The specimen represents Milde’s “forma 
incisa”’ and was found growing with a few others in a sandy plain. 
This is the first instance of genuine specimens of this rare fern being 
_ found in Massachusetts since Dr. Torrey’s Deerfield specimen—date 
unknown—many years ago, and its rediscovery now will give to our 
botanists an additional stimulus to exert themselves still further in 
the search for additional stations. 
Since I sent the above I have personally verified the rediscovery. 
There were in all about 125 plants growing on an exposed sandy 
plain, where the spores may have been blown from some of the higher 
hilly regions of the surrounding country. The specimens were all 
small, and it would seem as if the station could not have been there 
a very long time, probably, allowing three years growth from spores, 
and two for the largest form above ground, not more than five or 
six years, or there would have been some more fully developed 
plants. 
I am now desirous of obtaining southern and western forms of 
all of our Botrychia and will be very grateful to any one who will 
favor me with specimens, 
If I can make any return it will afford me much pleasure to do 
so. Gro. E. Davenport. 
§ 241. Herb. Mass. Hor. Society.—The collection of N. Ameri- 
can Ferns which I[ have prepared for this Herbarium being about com- 
plete, I now propose adding to it the remaining Vascudur Cryptogamic 
plants of the United States, and respectfully solicit specimens from 
the botanists of the country for that purpose. Any specimens sent 
will be thankfully acknowledged, and placed in the Herbarium with 
donor’s name and ticket, and, whenever possible, I shall be glad to 
supply any desiderata.

§ 242. Musci Appalachiani. Supplement I.—Tickets of 100 
specimens of Mosses collected mostly in the Eastern part of North 
America, by Coe F. Austin, Closter, N. J., price 25 cents. Mr. 
Austin’s supplementary collection is now ready for distribution, at $6 
the hundred species, each represented by from ten to fifty speci- 
mens.
