 " mostly southward," according to Professor Gray's Manual. 



B. ohliquum (Muhl.), appears to be chiefly distinguished by its larger 

 size, more compound fertile frond, and the narrower oblique divisions of 

 the barren one. B. ohliquum (Muhl.), Pursh. Fl. Amer. Sept., vol. ii.

Ophioglossum. 



[0. vulgatum, L., which is widely distributed throughout Europe and 

 Northern Asia, and grows also in the Northern United States, although 

 there " not common," is to be looked for in Canada. In one of its 

 forms [0. reticulatum, Linn.), it extends to the West Indies.] 



Nat Ord. LYCOPODIACE^.* 

 Plananthus. 



p. Selago, Pallisot-Beauvois. — Stem dichotomously branched, erect, 



* In this order the arrangement of A. M. F. J. Pallisot-Beauvois is adopted, 

 as it seems to atford the best basis for a readjustment of the genera of Lj/co- 

 podiacece, which is much required. For P.-B.'s genus Lepidotis, I have thought 

 it better to substitute the name Lycopodium, an old name that should not be 

 discarded.
