 Deparia prolifera (Kaulf.) Hook. Sp. Pil. 1 : 85. 1846. 



Dicksonia prolifera Kaulf. Enum. Fil. 225. 1824. 



In wet woods at an elevation of about 3000 feet, near the head 

 of the Wahiawa, this fern was occasionally found. Hillebrand 

 united this species with Asplenium deparioides, but apparently 

 without valid reason for the two species are easily distin- 

 guished.
