$79. Variation of Ferns.—I am glad to see that Prof. Tucker- 
man in his list of Amherst plants throws out the so-called varieties, 
Onoclea sensibilis, var. obtusilobata; and Osmunda cinnamomea, 
var. frondosa. It would certainly seem that they are not “ varie- 
ties” in the general acceptance of the term, as the plants which 
abies them one year, not only seldom produce them ‘a second, 
ut are more likely not to produce them agin, at least I findit so. In 
my herbarium I have the same thing (this half-way state between 
sterile and fertile fronds) occurring in almost every species which 
has dimorphous fronds, and in the following species, in a very pro-
