50 years old from the germination of the spore to the 
time of its collection. 
It is not possible by this means to determine the ex- 
act age of the plant but there are two important as well 
as interesting points involved. 
1. There is sufficient data to warrant the conclusion 
that the plant has lived quite a long time. 
2. A plant which takes such precaution to retain its 
old leaves must certainly derive some benefit from them 
and it is not improbable that these dead leaves in the 
process of decay and under the influence of the warmth 
of the summer sun yield something that is of vital im- 
portance to the plant in its subsequent growth. 
Commenting upon this note Dr. Jennings says: “I 
had not hought of any particular old age characteristics 
when I took that specimen from its home on the ho 
(on that day) dry cliff at the top of the talus slope. Now 
that I think of it I am sure that there could have been 
collected at that place others which would have shown 
almost twice as big a bunch of leaves. Whether these 
would really have been older or not I do not know. Per- 
haps they might have borne more leaves each year or 
have retained the old leaves longer but I am sure there 
were much larger bunches.”

Where Ophioglossum grows. (A Multiple Report.) 
As a result of my query about the habitat of Ophi- 
oglossum in the last number of the Fern JourRNAL for 
1914, many interesting reports have come in and I am 
printing them just as received. In connection with 
these I am printing also the comment of D. C. Eaton 
in his “Ferns of North America” on the same subject. 
No matter how thoroughly one may have studied any 
particular fern of our Eastern states, it is always safe
