240 Ma.coii — .1 New Name for Kauljussia Blaine. 



The type of Kaulfussia Blume and therefore of Christensenia is Aspidium 

 a e.tculi folium with the following synonymy : 



Christensenia aesculifoiia (Bhime). 



Aapidium aesculifollum Blume, Enum. PI. Jav. 2 : 143. 1828. 

 Kaulfussia aesculifoiia Blume, Enum. PI. Jav. 2 : 200. 1828. 



The distribution of true C. aesculifoiia outside of Java, the type region, 

 is more or less uncertain. De Vriese and Harting, in their Monographic 

 des Marattiacees (1853), recognize four species of Kaulfussia, viz. A', aescu- 

 lifoiia Blume, 1. c, from Java and Leyte ; K. assamica Gritlith, Asiat. Re- 

 searches 19^ : 108. pi. 19. 1836, from Assam ; A'. Korthalsii de Vriese, Epim. 

 Ind. Sem. Hort. Lugd. Bat. 1851, from Sumatra and Luzon; and A'. Loh- 

 hiana de Vriese, in de Vriese and Harting, Mon. Maratt. 14. 1853, from 

 Java; of which the last two are figured. "We have not undertaken 

 to determine the status of the last three. Most writers have followed 

 Hooker and Baker in merging them with aescitlifoUa. ; but it is by no means 

 unlikely that careful study will substantiate their claim to recognition, in- 

 cidentally offering an explanation for the wide range of variation which 

 so-ciiUed aesculifoiia has been supposed to have.
