1905] Gilman, — Two Ferns New to Vermont 103 
By way of summary it may be said that our common hedge-mustard, 
having smoothish inflorescence and essentially glabrous pods, should 
be called Sisymbrium officinale, var. letocarpum, DC., while the typical 
hairy-podded form, hitherto chiefly European in its distribution, 
proves to have been some years established in California and has 
now been found in Maine. It is therefore likely to be found else- 
where in our country. 
GRAY HERBARIUM. 
TWO FERNS NEW TO THE FLORA OF VERMONT. 
CLARABEL GILMAN. 
THE western half of Vermont is known as the home of rare and 
beautiful ferns, which grow among the mountains and upon the lime- 
stone rocks; but the portion east of the Green Mountains is not to 
be scorned by the student who delights in large and fine plants of 
the commoner ferns, as wellas in new specimens of the rarer species. 
It was my good fortune last summer to find in the woods and on the 
hillsides of the town of Chester, Vermont, many unusually fine plants 
of some of the larger ferns, such as Wephrodium spinulosum and its 
variety intermedium, Nephrodium Noveboracense, Athyrium filix-foe- 
mina and thelypteroides, Polystichum acrostichoides, Nephrodium mar- 
ginale, and Struthiopteris Germanica. Woodsia Ilvensis, Asplenium 
ebeneum and Trichomanes, and Adiantum pedatum are also among the 
natives of this region. Some fine specimens of Botrychium lanceola- 
tum were gathered in a moist hollow on a hillside. Of course the 
common ferns of meadow, swamp, and pasture are found in Chester, 
as in most parts of New England. In all, 25 species and 6 varie- 
ties were gathered. But the special finds of the season were two 
varieties, one of which, so far as I have been able to learn, has not 
been previously reported in Vermont, and the other not in New 
England. 
The first of these is Mr. Gilbert’s variety fructuosum of Nephrodium 
spinulosum. ‘The plants were first found August 18th. They grew 
around the base of a rock on the edge of a fine maple grove, and 
at once attracted attention by their richness and luxuriance of growth
