468 BOTANY. 



under obligations to the author, while his easy-flowing, graceful and 

 sprightly pages of biographical matter, glowing with the enthusi- 



tact in their natural haunts with the objects described, will render 

 his book a pleasing and attractive one to the general reader. 



But the author is not alone entitled to our thanks or our con- 

 gratulations. It must not be forgotten that Dr. Hayden's early 

 explorations in the Upper Missouri region, together with the later 

 collections made under his direction as Geologist in charge of the 

 Geological Survey of the Territories, have furnished both the 

 basis and the occasion for the present report, and that to his wise 

 liberality we are indebted for its publication. — J. A. A. 



BOTANY, 



frond. — In 1873, Mr. E. W. Munday sent, from Syracuse, New 

 York, a large specimen of Botrychium simplex, having four pairs 

 of broadly wedge-shaped divisions to the sterile part of_ the frond, 

 these merely incised at the broad terminal margin. From Syra- 

 cuse, Mrs. Styles M. Rust now sends a very robust specimen, ap- 

 parently of the same species, but of a ditferent aspect, the divisions 

 of the sterile part of the frond being more approximate, narrowly 

 oblong in shape, and strongly pinnatifid. The texture is that of 

 B. simplex, i.e., thick and rather fleshy. This may interest our 

 fern-students and collectors. The variety may lake the name of 

 var. bipinnatificlum.—A. Gray. 



Fucas serratus.— Colonel Pike has personally assured me that 

 this Fucus was abundant at Newburyport when he was there in 

 1852. Rev. J. Fowler sent me some from Pictou harbor in 1869, 

 and again lately in large quantity, the plant several feet long, 

 and fruiting abundantly. He writes that he collected it Nov. 1, 

 1874, and that "it seemed abundant on the rocks round the har- 

 bor, and had every appearance of being a native."— Daniel C. 

 Eaton. 



Menyanthes trifoliata, the Bud-bean, has dimorphous flow- 

 ers, according to the observations of C. A. Wheeler, of Hubbards- 



Germany (in "Botanische Zeitung," 1867), includes this in a list 

 of, dimorphic genera. It had escaped our attention. — A. G.
