held on August 24 of last year, and a brief account appeared in this 

 journal for December, 1898. By direction of the Chapter members 

 the papers presented at the open meeting have been printed in the 

 form of an attractive pamphlet of 32 pages. 



The first paper on " Abnormal Forms aijd Hybridity in Ferns " is 

 by Mr. George E. Davenport. It contains an interesting account of 

 the probable causes which lead to the ])roductions of the forms of 

 Osiiiunda ciiinainovica and Onoclca scnsibilis, known respectively as 

 frondosa and obtiisilobata. The hybridity of ferns is also interestingly 

 recounted. "An Interesting Variety of Osiniinda Claytoniana" is 

 the subject of a short paper by Dr. A. J. Grout. " Notes on the 

 Ferns of the Ural and Caucasus Mountains " are treated by Mary A. 

 Flemming, and gives quite a picture of the fern beauty of that far- 

 away place. Mr. W. N. Clute has a paper " On the Distribution of 

 Some Eastern American Ferns," in which he points out the curious 

 distribution enjoyed by some of our species. The remaining papers 

 are: " The Genera of Ferns, a Study of the Tribe Aspidieae," by B. 

 D. Gilbert; "A Peculiar Botrychium," by A. A. Eaton, and a "Study 

 of Ophioglossum " by Mrs. E. G. Britton. This is a very interesting 

 set of papers, and it is to be hoped that frequent meetings may be 

 held in the future. — F. H. K. 



Missouri Botanical Garden, Tenth Annual Report. St. Louis, 



Mo.: 1899. 



The handsome annual volume, issued by the Missouri Botanical 

 Garden, has come to be a looked for and welcome visitor to botanists 

 the world over. It is a pleasure to note the care and precision with 

 which the will of the benefactor of the garden, the late Henry Shaw, 

 has been carried out. If the example of this garden and the good it 

 is accomplishing can be suitably impressed upon people of wealth, we 

 shall certainly have others. 



The directors of the garden take this opportunity to show the 

 progress made and the work accomplished during its first decade. 

 They have in successful cultivation over 5,000 hardy plants and 3,003 

 growing under glass. The herbarium includes about 307,460 speci- 

 mens, and the library 32,119 books and pamphlets, and 212,042 index 

 cards. 



The scientific papers in the present volume are two in number — - 

 "Notes on the Grasses of the Bernhardi Herbarium," by F. Lamson 

 Scribner, and "A Sclerotioid Disease of Beet Roots," by Hermann 

 Von Schrenk. There is also a biographical sketch and portrait of 

 Edward Louis Sturtevant, by Prof. C. S. Plumb. Besides the lists of 

 additions to the herbarium, library, etc., there is an index to the first 

 ten volumes of reports. — F. H. K.
