PLATE 7 
Drawings of intracellular bodies in tissues from the tiller bases of Harvest Queen 
wheat plants affected by the rosette disease. 
Figures 3 and 9 from material killed and fixed in Flemming’s weak solution, all 
other figures from preparations killed and fixed in weak chrome-acetic solution. All 
preparations were stained with Heidenhain’s iron-alum haematoxylin. Figures 1, 
3, 4, and 9 show bodies in relation to the host nuclei marked N. 
The remaining figures show bodies of somewhat unusual types. Figure 8 shows an 
almost spherical body with an unusually large central vacuole. The matrix surround¬ 
ing this vacuole contains many small vacuoles*
