I am indebted to Dr. J. Schenck, of Mt. Carmel, Illinois, for an op- 
portunity to examine them. Unfortunately it is now too late to 
have this fern figured in the “ Ferns of North America.” ; 
23. Aspidium mohrioides, Bory,—hitherto known only from 
Chile, Patagonia and the neighboring islands, has been discovered 
near Mt. Shasta, California, by Mr. Lemmon. It belongs to the 
section Polystichum, having an entire orbicular indusium. The 
fronds are very chaffy, a span to a foot long, linear lanceolate, pin- 
nate; the pinne crowded and often imbricated, pinnately lobed, the 
lobes crenate or crenately toothed, but never aristate or aculeate as 
in A. aculeatum, munitum, acrostichoides, etc. t will be figured in the 
last part of the “ Ferns of North America.” D. C. Eaton. 
'§$ 360. Schizea pusilla, Pursh.—Specimens of this fern exist in 
the Newfoundland collection of De la Pylaie, but it has been com- 
_ monly supposed that they must have comefrom New Jersey. Miss 
Elizabeth G. Knight, of New York, has made a discovery which 
goes far to make it probable that the Newfoundland habitat is not a 
mistake after all; for last August she collected small but fertile and 
unmistakable specimens of thisfern on the shore of Grand Lake, 
about twenty-three miles from Halifax, Nova Scotia. The speci- 
mens have fertile fronds an inch and a half high, the fruit not fully 
matured. The plants are not abundant; they grow in company 
with Lycopodium tnundatum and Littorella lacustris, Linn., among the 
rhizomes of Osmunda regalis. Schizea pusilla has proved perfectly 
hardy in alittle artificial bog in my garden in New Haven, and is 
now to be sought for with renewed scrutiny all along the coast from 
‘Long Island to Newfoundland. 
The Littorel/a is, I believe, new to America. It is a little plant 
having a tuft of a few grass-like leaves an inch or two long, long- 
pedicelled solitary monopetalous staminate flowers with exserted 
anthers, and sessile apetalous pistillate flowers in the axils of the 
leaves, enclosing a one-ovuled ovary and a long and slender style. 
The moneecious inflorescence and solitary seed separate it generically 
from Plantago. Miss Knight is to be congratulated on her double 
discovery. Lake Champlain, Pringle. Eps. D.C. 5, 
§ 361. Anew Hawaiian Fern.—Aspidium (Cyrtomium) Boydiz: 
—-Pusillum, cespitosum : frondibus subspithameis chartaceis glabris, 
simpliciter pinnatis; pinnis 8-9 lin. longis 2—24$ latis lanceolatis 
crenatis obtusiusculis basi latere inferiore cuneatis superiore paullo 
dilatatis vix auriculatis, terminali incisa maxima; venulis pellucidis 
unicam Cyrtomii arcuum seriem formantibus czterum liberis; soris 
a margine remotis magnis; indusiis orbicularibus levibus margine 
crenulatis centro depresso affixis, sporanglis annulo 15-16—articulato 
donatis. 
Valleys of Oahu, 80-100 feet above the sea, collected by Miss E. 
S. Boyd, a lady who has taken a great interest in Hawaiian Ferns. 
This is many times smaller than A. falcatum, which is also found in 
the Hawaiian Islands, and it also differs from that species in having 
but a single row of areoles along each side of the midvein. The
