trinervium. This striking variety occurs abundantly at the Newcastle ond 

 of the Mourne Mountains, where it was first observed by W. H. P. in 

 1876, and where it forms a peculiar feature of the local flora. The fronds 

 are shaped like a cross-handled sword, owing to the extraordinary develop- 

 ment of the lowest pair of lobes, which sometimes measure three to four 

 inches across.
