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. polypodioides. The same is true of the picture and of the 

 type sheet of Fee's L. decrescens (Cuba, Linden 2019) ; and Fee's 

 description contains too many contradictions to be of any value. 

 L. mexicana Fee is later described by Fee 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. Feei of Jenman be clearly distinguished from S. 

 polypodioides for (1) the same plants show both forms of bases of the
