The authentic spécimen of this species is unknown to me.— The 

 plants occuring in the Buitenzorg Herbarium under the namc of A. 

 acutiiisciiliim BL. hâve the pinnae varying from serrate-crenate to lobate- 

 crenate with the crenations (teeth, lobules) entire or the central ones 

 2-crenate or 2-serrate and the lower not rarely more copiously serrate-crenate 

 or dentate-crenate. — A plant from Java, gathered and determined by 

 Raciborski, lias the lower pinnae subpinnate towards the base, with the 

 segments resembling the piiinulae of A. ciineatum Lam.; the spécimen, 

 however, differs, distinctly from the next preceding. 



Plants from Sumatra, gathered by BiiNNEMEljER, are appareiitly inter- 

 mediate between A. aciiiiusciiliini BL. and A. caudatiim FORST. ; some of 

 the spécimens are approaching the former, and others approaching the latter.

A spécimen from Sumatra (Dell, B a n d a r-b a r o e, in secundary

 fronds very large, to 4'/2m. long (including the stipe.^), tiie pimiae to 

 40 cm. long, 2'/2 ^ru- broad.
