PLATE 77 



A. — Clump of Saccharum spontaneum, showing characteristic size and habit of 

 healthy plants under natural conditions. The measure is 2 meters tall. 



B. — Clump of Saccharum spontaneum infected with Sclerospora spontanea. When 

 transplanted to this container in Cebu the infected plant comprised a single shoot 

 separated from the clump shown in the preceding plate. This shoot continued to 

 develop vigorously in spite of the downy mildew until after 5X months it had produced 

 the thriving clump shown. Conidiophores were still being produced in abundance, 

 especially by the younger stalks. Same measure as in A.
