It occurs in the Gonapinuwela-Baddegama Elpitiya area, in the southern procince of Ceylon. The most characteristic symptoms of "leaf scorch decline" are a necrosis on the leaves root decay and reduction in nut production. Fusarium spp. and Celindrocarpon sp. appear to be associated with root decay.
