it is entirely hidden. The plurilocular sporangia may be recognized 
by their resemblance to those of Æctocarpus. The identification of 
our specimens is due to the courtesy of Professor Farlow. 
Since these notes were in type another very small specimen of 
Pogotrichum filiforme has been discovered, which shows that this in- 
teresting form still persists in New England. It occurred now upon 
Sertularia pumila, Linné, among Sphacelaria, upon a bit of Asco- 
phyllum which also harbored Clava /eptosty/a, Ag., a hydroid which 
is rather common on the Fucacee at low water mark on exposed 
shores. I am informed by Mr. G. W. Gray, Curator of the Marine 
Biological Laboratory, that the specimen in question was collected 
at Woods Hole about the end of last October. Since Vineyard Sound 
is a waterway used by many foreign vessels, it is not improbable that 
this plant is merely a waif from alien waters. Possibly future collec- 
tions may cast light upon this interesting question.

PLANTS FROM THE DUCK ISLANDS, MAINE. 
EDWARD L. RAND. 
Tur Duck Islands, two in number, and small in area, lie seaward 
about ten miles off the coast from Southwest Harbor, Mt. Desert 
Island, Maine. The smaller island, Little Duck, is high, poorly 
wooded, partly cleared, and uninhabited. From a botanical point 
of view it is little explored. "The larger island, Great Duck, is divi- 
ded by a marshy depression from north to south, and is mostly 
cleared, but has some old woods still remaining. It is now the site 
of a lighthouse, and therefore inhabited by others besides the fisher- 
men who often make temporary summer homes on both islands. Be- 
fore the lighthouse was built, however, it had been long inhabited, 
until fire destroyed the farmhouse and forced the settler to make a 
- home elsewhere. Sheep now graze over a large part of this island, 
and, as usual, make collecting most unsatisfactory to a botanist. 
Some years ago, the late John H. Redfield, while engaged in 
work on the flora of Mt. Desert, considered the plants of these small 
outlying islands of sufficient interest to warrant the compilation of a 
list, as he from time to time observed them. Two lists were pub- 
lished by him in the Bulletin of the Torrey Botanical Club, xii : 103
