DESCRIPTION OF FIGURES. 

 Plate I. 



Figs. 5, 6, 17, 18, 19 and 20 were drawn from material in the fresh 

 condition. 



The remaining figures, except i and 2, are from sections of material 

 fixed in Flemming's weaker solution, and stained in Carbol Fiichsin and 

 Licht Grlin. 



Figs. I and 2 are from a strip of epidermis fixed in alcohol and stained 

 with Erythrosin. 



Fig. I. — Two germinating sporidia lying on the epidermis seen 

 in surface view, with their infection vesicles entering 

 the epidermal cell. x 800. 



Fig. 2. — A sporidium which has germinated, but failed to enter 

 a host cell, showing the different character of the 

 germ tube. x 800. 



Fig. 3. — A longitudinal section of part of an epidermal cell, 

 showing a vacuolated infection vesicle directed 

 towards the nucleus. x 800. 



Fig. 4. — A longitudinal section of a similar cell to Fig. 3, 

 showing a branched infection vesicle. x 800 



Fig. 5. — A living cell of the cortical parenchyma, entered by a 

 very young forked haustorium. The nucleus is 

 situated in the peripheral protoplasm and the chloro- 

 plasts are normal. x 650. 



Fig. 6. — A cell of the cortical parenchyma in transverse section, 

 entered by a straight haustorium which lies in the 

 protoplasm. x 650. 



Fig. 7. A cell of the cortical parenchyma which shows an older 

 haustorium in contact with the nucleus. The dis- 

 integrated chloroplasts lie near to the nucleus, and a 

 young haustorium is growing along a protoplasmic 

 strand from the opposite side. x 650.
