The genus Retinodendron has been examined in R. pallidum; 

 and figure 81 represents a germinating fruit which had been dis- 

 turbed in the course of its germination so that the direction of the 

 radicle had been changed. That change is of course immaterial to 

 the structure under examination. Figure 82 is an embryo viewed 

 with the radicle away from the observer. The placentar cotyledon 

 is folded rather than re volute. When the seedling develops, the 

 placentar cotyledon is seen to possess one marked horn, and one 

 scarcely defined. So far these horns have been found in Vatica 

 and Retinodendron alone.
