is a definite change of environment during development as in 
mammals, birds, or seed plants, while juvenile may be employed 
for the succeeding stages. Embryonic is however, the more re- 
stricted term and when there is a gradual transformation from 
the egg or spore to the adult form, the more convenient designa- 
tion is “juvenile” stage or organ. In cases where there is a 
definite metamorphosis or succession of forms as in some mosses 
or in insects the special terms applied to these stages may, of 
course, be most advantageously used for the special organs of 
the stage in question. 
ADDITIONS TO THE FLORA OF CEDAR POINT, II. 
Otto E. Jenni.xgs. 
The “ Flora of Cedar Point, published in 1904, was intended 
to be a complete list of the flowering plants and ferns of that lo- 
cality as collected during the summer of 1903 and as substan- 
tiated by definite prior reports of various other collectors. A 
list of 20 additions for 1904 was published in the May number of 
the Ohio Xatur.\list. During the 1905 session of the Lake 
Laboratorv of the Ohio State University a further opportunity 
was afforded the writer following up this line of study. In the 
following list are given those species which were collected on 
Cedar Point in 19()5 but which were not included in the former 
lists referred to. 
The total number of species of flowering plants and ferns re- 
ported for Cedar Point is now 449, — original “Flora of Cedar 
Point,” 3<S7 species; additions 1904, 20 species; Prof. E. L. Mose-
