species of Ewoascus was observed. The inflorescence is also 
attacked, resulting in the production of a dense agglomeration of 
flowers, due to many of the pedicels giving off branches. 
these branches assume a vegetative character, and form small 
witches’ brooms. The flowers in such clusters are often hyper- 
trophied and abortive. 
Tt has been observed that in those plantations where witches’ 
brooms were present much of the fruit was damaged. This injury, 
ver, was generally considered by the planter to be identicab 
with the “black pod” disease of cacao pods in the West Indies, 
caused by Phytophthora omnivora. A careful investigation of the 
subject by Hall and Drost showed that this was not the case, but 
that in reality the pod disease was caused by the same fungus that 
led to the production of the witches’ brooms. The induration of 
the fruit presents the following characteristics: the hardening of 
the tissues of the infected area, which often forms a swelling in 
young or half-grown pods; the swollen or gouty appearance of the 
fruit stalks, and the blackening of the diseased patch. Such diseased 
pods rarely mature, but fall before they are half grown. 
When witches’ brooms are present in quantity the trees are often 
wing to climatic conditions and the fact that the plants produce 
new shoots throughout the year, spraying with Bordeaux mixture 
is impracticable. As the disease spreads at a slow rate, the only

fallen fruit should be collected and burned.
