Oss.—This genus consists of about six presumedly dis- 
tinct species, and which are better recognised by seeing 
the living plants than by herbarium specimens. They are 
natives of New Zealand, Australia, and the islands of the 
Pacific. | 
In habit they agree with Blechnum, 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. caudata, which has two kinds of fronds, the 
fertile being contr. , and the sori sub-continuous.
