This species has been confused by Hillebrand and others with : 
D. media R. Br. (type from Australia), the lower pinnae of which 
become reduced to small triangular auricles. It is safer to main- ae 
tain the species as distinct under Gaudichaud’s name. An allied 4 | 
species with widely spaced pinnae, collected in the Fiji Islands 
by Capt. Wilkes, is mentioned by Brackenridge (Fil. U. 5- Expl. 2 
Exp. 138. 1854) as a “var. B.”’ a : 
Mr. C. N. Forbes’s D. Kunthiana var. depauperata (252 BM), a 
collected ‘‘on rocky ledges along the main Wahiawa,” is so MUC™ 
smaller than the other plants of D. Kunthiana as to have gi 
entirely different appearance. However, as to the form of the leaf, 
pinnate below, pinnatifid in the upper half, and the form of t 
linear-lanceolate scales, they are similar. These small plants #
