The Ohio Naturalist. 
[Vol. n, No. 2 , 
reported were excluded because uuauthenticated b) r 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. 
Item 2. Miss Ruth E. Brockett, of Rio Grande, Gallia 
County, Ohio, has found the Showy Skullcap, Scutellaria serrata 
Andr. , previously uureported 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 Buckeye (Aesculus 
octandra hvbrida), and others too numerous to mention. 
Item 3. An interesting and suggestive study has been pub- 
lished by Herman Dingier (Muenchen) on the organs for wind- 
dispersal ( flug-organe) in the Vegetable Kingdom. The title of 
the book is “ Fin Beitrag zur Physiologic der passiveu Bewegun- 
gen im Pfianzenreich. ” After describing fully the mechanics 
involved, and the methods of investigation, the author enumer- 
ates the Chief Types of the flight organs as follows (prefixing to 
the word “flyer” the descriptive words, 1, 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):
