LYCOPODIUM SABINAEFOLIUM Willd. var. sharonense (Blake) comb. 
nov.— L. tristachyum Pursh var. sharonense Blake! Fern Bull. xviii. 9 
(1910). L. complanatum L. var. sharonense (Blake) Farwell, Ann. 
Rep.: Mich. Acad. Sci. xviii. 94 (1916), as to syn.— Speciei formae 
typicae simile, pedunculis longioribus (6.1-7.6 em.) exceptis.— The 
plant which I described some years ago as a variety of Lycopodium 
tristachyum proves, when compared with ample material, to be refer- 
able to L. sabinaefolium Willd. From all specimens of that species 
examined, however, it differs in its very long (6.1-7.6 cm.) peduncles. 
The fairly extensive series of specimens in the Gray Herbarium and 
the herbarium of the New England Botanical Club shows scarcely 
any peduncles longer than 4 cm., and the average is only 2-3 cm. 
Willdenow’s types, which I examined in 1914 at the Berlin Herba- 
rium, have peduncles 1.5-2.3 cm. long, and were originally labelled 
“Lycopodium alpinum. Canada. (Richard.)” 
The specimens on which this variety was based, from Sharon, Hills- 
boro Co., New Hampshire (42° 50’ N. Lat.) are of especial interest 
as affording the southernmost known locality for any form of the 
species. Mr. Maxon’s record (Am. Fern Journ. v. 3 (1915)) of Hab- 
erer’s Oneida County (New York) specimens is very nearly on the 
same parallel but is slightly more northern. There appears to be no 
other New Hampshire record for any form of the species. 
In the last edition of Gray’s Manual (ed. 7. 58 (1908)) Lycopodium 
sahinaefolium is reported from Staten Island, on the authority of 
specimens collected by J. C. Buchheister. Plants from Mr. Buch- 
heister, collected in sandy barrens near Rossville, at a station said later 
to be destroyed by fire, and labeled Lycopodium sabinaefolium, are 
in the Gray Herbarium. Although they are merely young plants with- 
out fruit, it may be stated with certainty that they are not L. sabinae- 
folium, but that they are either L. tristachyum or L. complanatum var. 
flabelliforme. The record of L. sabinaefolium from Staten Island 
should be expunged.— S. F. BLAKE, Gray Herbarium. 
Vol. 20, no. 280, including pages 21 to 40, was issued 12 February, 1918.
