appear that forking fronds had grown on the same plant 
two years in succession. Of course, such may have been 
collected the previous season, but it seemed strange that 
not one specimen should have been found to have forked 
in 1916 as well as in 1917. : 
It is more common to find a number of fronds having — 
abnormal lobes at the base on a single plant, than to find 
several with abnormal tips on one specimen. No record 
has been kept of the place and date of collection of any 
of those used in illustrating this article, but it is safe to 
say that all were collected within six miles of Manlius 
and most of them within 3 miles. A great many better 
ones have been distributed to members than some used 
for the cuts. By oversight the plate showing tips does 
not include a normal one for comparison with the others, 
but the other plate happens to show several of the normal 
tips among the abnormal bases. It is well to notice 
that Figures 1 and 2 on plate 6 are of normal base 
lobes. Also that this plate happens to show fronds 
various stages of spore development.
