Tue Boston FERN SHOW 101 
the floating fern, Salvinia, the four-leaved clover ferns, 
Marsilia quadrifolia and M. Drummondii, and the horn 
fern, Ceratopteris pteridoides, found in Florida, floating 
on streams. Here also were the non-fern types, [soetes, 
Selaginella, Psilotum, an epiphytic lycopod type of the 
tropics, and Equisetum scirpoides as a vigorous pot plant. 
We may hope that this, probably the first horti- 
cultural exhibition mainly devoted to ferns to be held 
in this country, may be regularly and widely repeated. 
Certainly the members of the American Fern Society 
do not require any arguments to convince them that 
these, their favorite plants, are worthy of such recogni- 
tion. 
LIST OF FERN SPECIES EXHIBITED. 
In the list which follows, undoubtedly some few species 
have been unintentionally left out. It makes no real 
attempt at scientific accuracy of nomenclature, but 
is aimed rather at listing under some approximately 
correct name, all the ferns exhibited, and it is hoped 
that it may serve as a basis for a more accurate and 
complete list of horticultural fern species in general. 
As it stands, it probably includes nearly all the ferns 
which may be considered commercial forms. Some 
additions, of course, must be made. Not all the current 
forms of Pteris and Nephrolepis are shown, and some 
other types must probably be added, but with these 
possibilities, the present list is offered as preliminary 
to the drawing up of possibly a standardized generally 
accepted set of names. 
In conclusion, it may be added that Mr. Wm. R. 
Maxon, of the Smithsonian Institution, Washington, 
will be glad to receive herbarium specimens of various 
cultivated ferns, and to give identifications when de- 
sired. At the Brooklyn Botanic Garden, I shall be 
glad to receive living specimens of cultivated ferns, and 
to identify as far as possible varieties of Boston fern
