PLATE 76 » 



Corner of a native-grown maize plot in the interior uplands of Cebu. At the edge 

 of this field, in which many maize plants were being killed by downy mildew, were 

 occasional clumps of the wild grass (Saccharum spontaneum L.) called "bugang" in 

 the Visayan Islands. One of these clumps, which was severely infected with Sclero- 

 spora spontanea, is shown at the left. The older, primary stalk of this clump, had died, 

 but although the remaining shoots were apparently uninjured, great numbers of 

 conidiophores were being produced on them, especially on the one held out for inspec- 

 tion. The base of this shoot was a few feet farther down the steep slope at the point 

 indicated by the arrow. Behind the central figure can be seen a maize plant notice- 

 ably discolored by the downy mildew.
