In taking up Mettenius 1 specific name Christensen has passed by two ot 

 earlier date, either of which is available. There appears to be no reason for 

 allowing Wallich's nomen nudum t<> Invalidate the same name adequately pub- 

 lished by Sweet the following year. But even should this be done. Presl's name 

 WOUld have to be taken up. The doubl expressed by Presl relates merely t<» 



the very questionable reference of this plant to the genus Polystichum, a doubl 

 abundantly sustained some four years later by Hooker, who recognized in it 

 a monotypic genua t<> which he gave the name Fadyenia. Presl's new specific 

 term was simply a substitute for the homonym of Hooker and Greville and 

 was placed with doubl under Polystichum.

A NEW NAME FOR ANAXETUM. 



The genus Anaxetum was based by Schotl on the single sp< 

 Polypodium crassifolium L.. which was made the subject <>f an excel- 

 lent illustration. Fee called attention to the unavailability of the 

 name, Anaxeton having been applied previously by Gaertner to a 

 new genus of Compositae, and elevated Presl's section Pleuridium t<> 

 generic rank', expressly founding the genus On Polypodium crassi- 

 folium,) surely in ignorance of the genus of mosses previously so 

 named by Bride! ami since generally adopted. No other name hav- 

 ing been published in the interim the following is proposed:
