Hab. New Bruns\vick. B. N, Kendal, JS'^^.-This species dgain is noNv, for the first time, ascertained to 

 be a native of N. America. It may perhaps be frequently found among maritime rocks. I have specimens 

 I can scarcely distinguish from it, from the West Indies.]

 that an opinion prevails that this plant should be referred to Zomana (Stegania, Br,): but the indusium is 

 certainly not marginal. The fructification may be considered that of Blechnum, the habit that of Lomaria, 



2. B. doodioides; fronde elongata lanceolata pinnata, pinnis suboppositis basi lata ex- 

 auriculata lato-lineari-oblongis sensim acuminatis paululumfalcatis versus apicem obscure 

 serratis infimis parvis rotundatissuperioribus multo angustioribus soriferls, son's continuis 

 vel ssepissime interruptis. 



Hab. Interior of N. W. America. Bouglas,— 0^ this plant two specimens were sent to me by the late Dr 

 Gairdner, (then resident at Fort Vancouver on the Columbia,) which were gathered in the interior by Mr 

 Douglas : but whether in the Hudson's Bay territories, or, as is possible, in N. California, I am uncertain. I am 

 disposed to believe in the former country, because there is nothing of the kind in Mr Douglas* Californian Her- 

 barium. It is a very distinct plant, almost combining the character of Woodwardia, or Boodia, with those 

 o^BlecJinum. The veins are obliquely parallel with the costa, forked, and not anastomosing in the sterile 

 pinnae: when the fructification appears, the lower branch of a vein anastomoses with the vein immediately 

 above it, and in the interior of that vein (next the costa) the sorus is formed. In the lower of the fertile 

 pinnae, the indusium frequently stands unconnected and more or less distant, as in Woodwardia, but gene- 

 rally forming a continued line, from the union of the adjoining indusia. The stipes is dark purple, the upper 

 (fertile) pinnae are so narrow that the sori occupy nearly the whole surface, as in B. boreaie.
