(Table VI). Some of the seeds, notably those of Con- 
cordia, did not germinate at all, although the material 
used was in good condition (see control). Instead of 
germinating, the seed became quickly enveloped with 
a thick felt of mycelium which often spread to the 
surface of the soil. Most of the developed plants suc- 
cumbed to the attacks of the fungus. The basal part 
of the stem often showed a dark reddish colour. A few 
centimetres above ground the stem appeared water-soa- 
ked. Finally an extensive rot of the parenchymal tiss- 
ues just above ground commenced, and the fungus co- 
vered the area involved with its mycelium ancLconidia 
(fig. 1). Also the root-system became infected and de- 
veloped but poorly.
