1905 | Churchill, — Three Plants New to Vermont 99 
can readily be identified. Ch/orochytrium Knyanum Cohn & Szym., 
in Lemna minor L., L. gibba L., Ceratophyllum demersum L. and Elodea 
Canadensis Michx. ; Endosphazra biennis Klebs in Potamogeton lucens 
L.; and Phyllobium dimorphum Klebs in Lysimachia Nummularia L., 
Ajuga reptans L., Chlora serotina Koch, and Erythraea Centaurium 
Pers. Undoubtedly many other species occur in other hosts, and 
there is quite a field here for a careful and persistent investigator.

DICKSONIA PILOSIUSCULA FORMA SCHIZOPHYLLA IN VERMONT. — 
Last August, while devoting myself most assiduously to the ferns of 
Dorset, Vermont, I brought in one day, two fronds of what I at first 
supposed to be a peculiar form of Vephrodium spinulosum. In the 
autumn I sent them with a number of others to Mr. Davenport, who 
pronounced them to be not ZVepArodium, but a form of Dicksonza, 
found in Andover, Connecticut, in 1901, by Mr. A. Vincent Osmun 
of Amherst, and described by Mr. Clute in the Fern Bulletin for 
July, 1902, as Dicksonia pilosiuscula, forma schizophylla. I have 
compared the Dorset fronds with the type specimens at Amherst, and 
while these are larger, the peculiar texture and cutting are the same, 
and Mr. Osmun agrees in the determination. — Emity HITCHCOCK

THREE PLANTS NEW TO THE FLORA OF VERMONT. — There has 
long been a tradition that the Canadian Waterleaf (ZZydropAy//um 
canadense, L.) grew in Williamstown, Massachusetts; and naturally 
it has been sought for upon the slopes and in the ravines of Greylock 
Mountain, where its congener ZZ virginianum is common. In Rho- 
DORA vi. 155, 156, Mr. Deane cites the frequent reports of its 
occurrence in western Massachusetts, and notes nevertheless the 
want of any existing specimens from New England to substantiate 
these reports. Since then Mr. Hoffmann has reported (RHODORA, 
vi. 205) his discovery of the plant near Greylock in Massachusetts 
in the summer of 1904; and Mr. Deane’s prediction that “ botanists 
will certainly visit that locality again, and the species will surely come 
to light before long,” has been verified.
