56 ’ AMERICAN FERN JOURNAL 
Fatt Fruiting or THE INTERRUPTED FERN. We 
have a few plants of interrupted ferns (Osmunda Clay- 
toniana L.) in one corner of our yard. Last season they 
fruited twice. 
In looking through my diary, I read: ‘April 10th: 
interrupted ferns coming up.’ They fruited in May. 
e had a wet season and the plants were in good condi- 
tion allsummer. In September they put up new fronds, 
both fertile and sterile, not quite as tall as the first set, 
but well developed fronds. 
I have never found the var. dubia.A. J. Grout. In 
fact, I have never found the slightest variation in the 
interrupted fern. In its near relative, the cinnamon 
fern, we find the form frondosa, and plants with the 
fronds incised are quite common, but with the interrupted 
fern when we see one we see them all so far as my obser- 
vation goes. 
In the Fern Bulletin Vol. XV, No. 1, is an article on 
the fall fruiting of the cinnamon fern by Prof. Clute. 
In the southern states it has the habit of fruiting in the 
fall. This has been noted from a number of states, 
but not reported from the north. 
It would be interesting to hear if any member of the 
society has noticed the interrupted fern fruiting twice 
in one year.

Apropos of Ophioglossum, the members of the Fern 
Society may be interested in my observations. I have 
collected it but once, in a wet place in an old mowing 
lot on an abandoned farm at 1500 ft. altitude. The 
place had had no cultivation for 50 years or more, but 
ay had been cut nearly every season. My specimen 
was in the bog. I could never find another.
