Frontispiece. — Development of an Odontoglossum as figured by Noel Bernard in 1909. 

 Figure 1 is a sectional view of seed; the remaining figures are habit sketches ot emoryos and 

 seedlings, the last two indicating regions ot tungal infection by shading. Figure 3 is of special 

 Interest because it shows neatly coils of the fungus (considered Rhizoctonia lanuginosa), which 

 has entered by an "absorbing hair". It shows also amoeboid condition of nucleus of infected 

 cells. Figure 2 shows by vivid contrast the condition of an uninfected embryo at 4 months of 

 age, whereas the embryo of figure 3 is but one month old.
