This is a vcrv variable fern common in Ben«;uet and the neighl)Oring highland. 
Some specimens' seem too distinct possibly to 1* A. mgripes; but others, which 
seem unmistakably the Siime plant, agree for the mo^^t part with Bhime's diag- 
nosis and with some Javan specimens. As construed by Raciburski this is a 
very variable species in Java also. Some Benguet specimens have the lowest 
pinnae moderately reduced. Xotal)le points of agreement In^ween phmts of Java
