with it. With these are a few specimens of 4. Zrichomanes 
with large oblong pinnz, much as in specimens from Bermuda and 
tropical America. 
17. Pteris Cretica, L. The Florida plant, as exemplified in 
Capt. Smith’s specimens, is identical with the Mediterranean species, 
and has the same “firm coriaceo-membranaceous” texture of the 
pinne. This fern has not been gathered in quantity before for 
several years, Mr. Shockley’s specimens being few, and mostly with- 
out the rhizoma. 
18. Pteris serrulata, L. fil—This fern is announced in Mr. 
Davenport’s new “Catalogue of the Davenport Herbarium of North 
American Ferns.” It was discovered near Mobile, Alabama, by Mr. 
Charles Mohr about a year ago, and first identified by Mr. Daven- 
port. Mr. Mohr has also favored me with specimens, but I preferred 
to say nothing about the discovery till Mr. Davenport should first 
make it public. I learn from Professor Lewis R. Gibbes, that a 
Preris has sowed itself and grown abundantly on the walls of the 
College at Charleston, South Carolina. It will be very interesting 
to know whether this is Pterts Cretica or Pteris serrulata. Thata 
fern may become an introduced plant is proved not only by the 
instance described by Mr. Davenport at the end of his most valuable 
and interesting Catalogue, but by the fact reported in the London Times 
that Platycerium alcicorne has appeared wild in at least three places 
in England and Wales, the last time in the Cader Idris Mountains. 
1g. Asplenium ebeneum, var. proliferum.—Rachis proliferous 
near the base of the frond. Many tropical Asp/enia are known to 
be proliferous, but with the exception as A. ebenoides proliferous 
forms have not been hitherto noticed in the United States. Capt. 
Smith collected a few specimens of A. ebeneum near Ocala; and, 
looking at them closely, I find as many as three fronds with proli- 
ferous buds on the rachis just by the lowest pinne. One frond has 
three such buds, and from them young fronds one or two inches 
long have been produced. I find one frond, which I collected many 
years ago in Florida, similarly proliferous, though the young fronds 
have not shown themselves. 
20. Ophioglossum vulgatum, Plumier. This plant, whether 
Fern or only Fern-ally, has been found again in Florida, this 
time near Manatee, and by the indefatigable Dr. Garber. His speci- 
mens are much the finest yet gathered in the United States. Dr. 
Chapman’s original discovery was first noticed in the Torrey CLus 
BULLETIN of January, 1876, which notice was accidentally overlooked 
by Capt. Smith in his recent paper in the Botanical ars agg % 
307. United States Species of Lycoperdon.—By Chas. H. 
Peck, A.M. (Read before the Albany Institute, Feb. 4, 1879. 
Pamphlet, pp. 34.) A revision of the American species of the genus 
Lycoperdon ( Anglicé “ puff-balls ”) has long been needed, inasmuch as 
the literature of the subject is somewhat scattered, and in many cases 
not easily accessible to the student. This work has at length been ably 
accomplished by Mr. Peck, in the monograph before us. ‘The entire
