two more papers to his series on the effect of light on germination, and Kinzei" 

 publishes a second paper (preliminary statement) on his extensive researches on 

 this subject. Data enough are now at hand to get at some general principles. In 

 respect to the effect of white light upon their germination, seeds may be divided 

 mto four groups: those requiring light for germination (Rhododendron javaniam, 

 R. hirsutum, R. ferrugineum, Drosera capensis, etc.); those germinating more 

 quickly and fully in light (Veronica peregrina, Allium suaveolens, etc.); those 

 germinating equally well in light and darkness (Myrmecodia echimta, etc.); and 

 those retarded in germination hvi;«Kt /pu,j.-_ . ,.-^»- n.j:...i„.;<- Srtbtrun
