A careful study of ripe spores has convinced the writer that 
they are usually echinate, but occasionally quite smooth or 
very little echinate, so that the sole distinguishing character 
of P. Englert from the simple form of P. hastatum is not at all 
satisfactory. Henry’s specimen (n. 9897) from Milé district 
has the exact appearance of P. Englert delineated by Makino,* 
but possesses echinate spores, whereas some specimens from 
Japan of the typical P. hastatum have hardly echinate or per- 
fectly smooth spores ; in some cases two kinds of spores have 
been found from one and the same sorus. It is difficult to 
regard P. Englert even as a variety of P. hastatum, so I propose 
to.suppress the former altogether. 
Nakai + distinguishes these two plants by means of length of 
the stipe, which is in P. Englert more than 10 cm., and in the 
other less. This method is, however, altogether impracticable.
