A NEW NAME FOR KAULFUSSIA BLUME, A GENUS 

 OF MARATTIACEOUS FERNS. 



BY WILLIAM R. MAXON. 



By permission of the Secretary of the Smithsonian Institntion. 



The gcMicvic iiinuc K/nilfussia given l>y Bhinie in 1.S28 to n 

 Javan fern deserihed earlier in the same volume as Aspidiiim 

 arsrulifnliiim is invalidated l)y Kaidfussia Dennstedt (1818) 

 applied to a genus of Polygalaceae and by Kaulfussia Nees (1820) 

 for a genus of Compositae. Subsequently the name Macrostnma was 

 associated in manuscript, l)y (Iriffith, with a supposed second 

 species iassamira) of the same genus ; l)Ut Macrostotiut appears 

 never to have 1)een formall}' published and is in any event un- 

 tenable. So far as we know no other name has ever been pro- 

 posed for this peculiar genus of marattiaceous ferns, and we have 

 accordingly' renamed it as below, in honor of Herr Carl Christen- 

 sen , of Copenhagen , the first part of whose valuable Index Fdimm 

 now issuing we liave already had occasion to notice.*
