reported were excluded because unautlienticated by herbarium 

 specimens, and others were undoubtedly^ extra-limital for Ohio. 

 Two Annual Supplements to this catalogue have been issued, 

 bringing the number of species of the vascular plants, nearly all 

 authenticated, up to about 2,150. The mosses, the higher fungi 

 and the lichens have been listed with some degree of fullness, 

 but most of the other lower plants have been very incompletely 

 placed on record, though large collections, only partially worked 

 up as yet, are now in the herbarium of the State University. 



/few 2. Miss Ruth E. Brockett, of Rio Grande, Gallia 

 County, Ohio, has found the vShowy Skullcap, Scutellaria serrata 

 Andr., previously unreported for this State. The distribution, 

 as given in Britton's Flora, is New York and Pennsylvania to 

 North Carolina, Illinois and Kentucky. In the Rio Grande 

 region many interesting or new plants for the Ohio list have 

 hitherto been detected by Miss Brockett, as the Fringe Tree 

 ( Chionanthus virginica), the Purplish Buckej^e (Aesculus 

 octandra hybrida), and others too numerous to mention. 



Item J. An interesting and suggestive study has been pub- 

 lished by Herman Dingier ( Muenchen ) on the organs for wind- 

 dispersal ( flug-organe j in the Vegetable Kingdom. The title of 

 the book is ' ' Ein Beitrag zur Physiologic der passiven Bewegun- 

 gen im Pflanzenreich." After describing fully the mechanics 

 involved, and the methods of investigation, the author enumer- 

 ates the C/i/ef Types of the flight organs as follows (prefixing to 

 the word "flyer" the descriptive words, i, dust; 2, granule; 

 3, bubble ; 4, hair ; 5, pan ; 6, umbrella ; 7, sail ; 8, disk-twist ; 

 9, barrel-twist ; 10, plain-twist ; 11, screw, and 12, screw-twist):
