is a definite change of environment during development as in 

 inammals, birds, or seed plants, while juvenile mav 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. 



(Jtto E. Jexxixgs. 



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 26 additions for 1904 was published in the May number of 

 the Ohio Naturalist. 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 1905 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," 387 species: additions 1904, 26 species; Prof. E. L. Mose-
