Onoclea polypodioides Sw. is described as having clustered 
stipes, erect fronds, an inframarginal indusium, and as differing 
from Osmunda Spicant L. in magnitude, in the more acute and more 
curved pinnae, and in the remote not subconfluent fertile pinnae. 
These characteristics, taken with the clustered appearance of this 
scandent species, and with the smaller size of the European Spicant, 
fix the name without doubt upon the Jamaican fern described 
above. The dimorphous character of this species probably caused 
Swartz to change the specific name to onocleoides, before he finally 
transferred it to Onoclea, where he took again the original specific 
name polypodioides. He plainly states the synonym in each case, 
so that there is no reason for including both onocleoides and 
polypodioides as several fern writers have done. 
Several species have been reduced to synonymy with poly- 
podioides, either by Christensen or in this paper. Liebmann’s own 
sheet of L. fragilis can not be distinguished from young leaves of 
L. bolypodioides. The same is true of the picture and of the 
type sheet of Fée’s L. decrescens (Cuba, Linden 2019); and Fée's 
description contains too many contradictions to be of any value. 
L. mexicana Fée is later described by Fée as synonymous with L. 
fragilis Liebm. The shorter fertile frond and the lack of any 
distinctive character even in one of Liebmann’s own sheets prevent 
the separation of fragilis from S. polypodioides. 
Neither can L. Féei of Jenman be clearly distinguished from S. 
Polypodioides for (1) the same plants show both forms of bases of the
