It is gratifying to have to report that this important work is 

 advancing towards completion more steadily than heretofore. 

 The author informs his readers that the obstacles which retarded 

 the publication are now removed, and that the succeeding Parts 

 will now appear with regularity, and with as much " despatch as 

 is consistent with accuracy in description and illustration." 



This Part contains part of the suborder Lomarieae, viz. the 

 genus Lomaria, and part of the genus Blechnum. Of the former 

 genus fifty-five species are described, and of Blechnum forty. 

 Blechnum boreale of some British botanists {Lomaria Spicant, 

 Desv.) is described on pp. 14, 15, 16. The following is an extract 

 from the account of its range, statistics, etc. : — " Every European 

 botanist is familiar with the Fern now under consideration, for no 

 species is more general in this quarter of the globe ; but, eastward, 

 it seems to become rare in Russia, and Lithuania is perhaps its 

 limit in that direction. I do not find it recorded as a Siberian 

 plant till it makes its appearance in Kamtschatka (stretching 

 south to Japan), and crossing the sea of Kamtschatka, in nearly 

 the same parallel of latitude, it again occurs at the southern ex- 

 tremity of the Russian possessions in North-west America, and 

 the northern extremity of the British possessions there ; nor -does 

 it appear to exist in any other spot of that vast continent. No- 

 where in the United States." 



Its range in Europe is from Lapland to Spain, and from 

 Madeira and the Azores to the middle of Russia. It re-appears, as 

 above observed, in the north-west of America. 



About a dozen synonyms for this Fern are given by the learned 

 author of ' Species Filicum,' and he invariably spells the specific 

 name Spicant, not spicans as suggested in the ' Phytologist,' but
