question. On the Ascophyllum were large tufts of Polysiphonia fas- 
tigiata (Roth) Grev., which occurs south of Cape Cod only rarely and 
in reduced form. The Rhodymenia fronds were large, often 3-4 dm. 
high and nearly as broad; and finally I found one fine tuft of Halosac- 
cion ramentaceum (L.) J. Ag. and several plants of Monostroma fuscum 
(Post. & Rupr.) Wittr; the Halosaccion has not been recorded south 
of Marblehead, and a doubtful record of the Monostroma at Newport 
is the only one south of Boston. As epiphytes on the Laminaria 
I noted Ceramium rubrum (Huds.) Ag., Chantransia sp.?, Pylaiella lit- 
toralis (L.) Kjell., Ectocarpus confervoides (Roth) Le Jolis, Antitham- 
nion floccosum (Muell. Kleen and Rhodochorton Rothii (Eng. Bot.) 
Nág.! 
All this taken together left no doubt in my mind that the northeast 
storm had brought the whole collection (there were thousands of 
Laminarias in sight) from the shores of northern New England. From 
the absence of other species of Laminariaceae, it is probable that they 
came from some quite limited station. I know of no point on the Mas- 
sachusetts coast where Laminaria longicruris. grows in large numbers, 
unmixed with other species of Laminaria or with Alaria, but on the 
Maine coast, east of Portland, there are stations where L. longicruris 
is abundant and unmixed with other Laminariaceae, usually in 
channels where there is a rather swift tidal current, but not exposed 
to the surf. If a gale happened to blow in a quarter that would send 
a heavy surf up such a channel, there might be torn up just such a 
“formation” or “facies” as I found, and the northeast wind might 
then carry it to the place where I found it. With the wind then pre- 
vailing it could hardly have originated west of Penobscot Bay, which 
would give 150 miles as the least distance it must have travelled. On 
returning to the beach the next day, I found the plants of the day 
before in a narrow windrow at high water mark, and rapidly decay- 
ing; the beach below and the water were bare and empty as usual. 
Now if I had been on an unfamiliar shore, and was making a record 
of the plants of the region, I think that under the circumstances re- 
corded, I should not have hesitated to enter in the list all the species 
I have named above; I have no doubt that some anomalies in regional 
1 It is noteworthy that among the 48 species recorded by Rosenvinge as coming 
ashore at Jutland, 44 were epiphytes on Ascophyllum nodosum and Himanthalia lorea 
(L.) Lyng. As long as the host plant is intact, the epiphytes find little change from 
their normal conditions, though most of them would speedily perish if detached from 
the host.
