others are more or less deeply cut to bipinnate and 

 these last are easily distinguished from P. angulare by 

 their glossy appearance and stronger substance. 

 Among the rest of the sporelings, angulare forms are 

 more numerous than those of acrostichoides but among 

 the forms resembling the first there are many that are 

 easily distinguished from the original plant. They are 

 just as finely cut, but there is something different in 

 their appearance. It would be hazardous to call them 

 hybrids, however, until another year's trial. 



Some good spores have been collected from the best 

 of these hybrids and no doubt after a few more trials 

 a new set of perfectly hardy plants will be obtained 

 that will have the delicate structure of the plumose, 

 crested and other forms of angulare.

POLYSTICHUM ACROSTICHOIDES RECURVATUM. 



It is a well-known fact that most of the abnormal 

 forms of ferns found in nature reproduce themselves 

 in a great percentage of cases from spores, the ab- 

 normality more or less accented with always some 

 normal plants among them. An abnormal plant means 

 a plant that has all its fronds affected in the same way ; 

 if only a few fronds are affected, it is usually acci- 

 dental and cannot be reproduced by spores. Through 

 the courtesy of our editor who sent me spores oiPolys- 

 tichum acrostichoides rccitrvatuni, I was able to raise 

 about one hundred sporelings of this form. They are 

 not big enough yet to form a definite conclusion, 

 nevertheless nearly all show signs of recurvatinn. —
