and that it must stand as the type of Asplenhtm rhizophyllum ; for

base. 



There is, moreover, in the Linnaean herbarium under the name 

 AHplenmm rhizophyllum a phmt of Camptosorus rhhophyllus re- 

 ceived from Kahn,'* apparently held by Linnaeus to be representative 



of his " species." 



The two species of Camptosorus Link, 1835, are: 



Camptosorus rhizophyUus (L.) Link, Ilort. Berol. 2: GO. 1S33, 



Confined to the United States and Canada : from Maine and soulliern Qnoboc 

 south to Georgia, Alaljama, and Texas. A form from Iowa has been described 



as variety intermedius Arthur.^ 



Camptosorus sibiricus Rnpr. Beitr, IMl. Kupf?. Reich. 3: 45. 1845. 



Known only from Siberia, China, and Japan. 



The West Indian plant should be known as : 



Fadyenia hookeri (Sweet) Maxon.

In taking up Mettenius* si^ecitic name Christenson has passed by two of 

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

 allowing' Wallich's }wmen itudtun to invalidate the same name adequately pub- 

 lished by Sweet the folliming year. But even should this be done, PresFs name 

 would have to be talien up. The doubt exi>ressed by Prcsl relates merely to 

 the very questionable reference of this plant to tlie genus Polystiehum, a doubt 

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

 a monotypic genus to which he gave the name Fadyenia. Presl's new specific 

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

 was placed with doubt under Polystichum. 



F, hookeri is known from Jamaica, Cuba* and Porto Rico. 



A NEW NAME FOR ANAXETTJM. 



The genus Anaxetuni was based by Schott on the single species 

 Pohjpodlum crasslfoUum L., which was made the subject of 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 rieuridium to 

 generic rank, expressly founding the genus on Pohjpodium cmssl- 

 folium^ surely in ignorance of the genus of mosses previously so 

 named by Bridel and since generally adopted. No other name hav- 

 ing been published in the interim the following Is proposed:
