DELPHINIUM AND COSMOS, WITH A NOTE ON 
SCLEROTIUM ROLFSII. 
iW. SMALL. 
In May, 1919, carnation plants in a garden near Kampala, 
Uganda, were observed to be dying by stages. The plants wilted 
gradually, paling of the lower leaves being succeeded by the col- 
lapse of the whole plant. The outer tissues of the underground 
parts of the stems of affected plants separated readily from the 
wood, and an easy pull from the ground broke off the plants. This 
disintegration of the tissues just under the soil surface was marked 
blackened sunken soft area, longitudinally arranged, and 
evidently a characteristic symptom of the disease. It was found 
to be of regular occurrence. 
Histological examination of the wood immediately under the 
discoloured area, which was invariably stained a dark colour, 
ace. 
n the dead leaves of wilted plants were found a species of 
Periconia anda Macrosporium which resembled JM. nobile, Vize,
