74 Maxon: Jamaican species of Polypodium 



names. As a matter of fact, Schkuhr's plate represents a plant 

 specifically distinct from the 7>iyos2troides of Swartz* Prodromtis ; 

 but Jenman, regarding the plate as truly illustrative of the Swartz- 

 fan species — apparenty on the strength of its citation by Swartz 

 faithfully describes the Jamaican plants agreeing with the plate 

 under the name inyosiiroides. The true myostiroides he describes 

 under the Hookerian nd^xn^ James o?ii. 



We propose to restore the name inyosuroides to the plants char- 

 acterized by Swartz in the Prodromiis, Schkuhr's plant has to 

 this day never received a valid name. 



The facts in the case, which are self-evident, were brought to 

 our attention by the manifest inappropriateness of Jenman's appli- 

 cation of the peculiarly descriptive term inyositroides — ''mouse- 

 tail-like/' with obvious allusion to the " mouse-tail " apex or canda 

 to plants not possessed of any such characteristic prolongation, 

 i. e., the plant figured by Schkuhr.
