A SPECIES OF KAULFUSSIA. HI 



The genus obviously belongs to the subtribe Marattiaceae or Danseacese, 

 in which M. Kaulfuss has placed it ; the correctness of this is farther 

 pointed out by the fact, that in Angiopteris the evolution of the young 

 frond takes place in a similar manner, so far at least as may be judged from 

 the universal presence of the two scales surrounding the base of the stipes 

 in this latter genus. 



M. Blumes' species may be thus distinguished : 



K. ^scuLiFOLiA fronde ternata, foliolis petiolatis, laterali uno alterove 

 geminato bipartitove, stipitibus hinc canaliculatis, capsulis subnovem-locu- 

 laribus, loculis per totam longitudinem dehiscentibus. — K. jEsculifolia 

 Bl. — Kaulfuss in Hook, et Grev. Icon. Filicum vol. 2. Tab. 229.
