PLATE 3 
A. —Two plants of Manobo Waxy Maize 14 days after emerging; the one at the 
left healthy, the one at the right already infected with Sclerospora philip pinensis , 
and showing etiolated stripes symptomatic of the disease. These stripes are rela¬ 
tively inconspicuous (a, a) and have a comparatively small area but are supporting 
abundant conidiophorz production from both their upper and their lower surface. 
The measure is marked in 5-cm. divisions. 
B. —The same plants 16 days later. The etiolated markings which have been devel¬ 
oped by the infected plant at the right are now relatively extensive and conspicuous 
and on them from both surfaces conidiophore production continues to take place in 
abundance. Measure as in A.
