Obs. — This genus consists of about six presumedly dis- 

 tinct species, and which are better recognised by seeing 

 the living plants than by herbai'ium specimens. They are 

 natives of New Zealand, Australia, and the islands of the 

 Pacific. 



In. habit they agree with BlecJmum, but are distinguished 

 by having definite oblong sori often in two rows, techni- 

 cally agreeing with Woodwardia, to which they are united 

 by some authors. With Lomaria they are connected 

 through D. caiidata, which has two kinds of fronds, the 

 fertile being contracted, and the sori sub-continuous.
