Abstract

Histological observations on trees suffering from brown bast were made on bark samples from partially dry trees and dry trees which showed external symptoms of dryness or malformations typical of brown bast. The histological behaviour of tissue is microscopically examined to reveal peculiarities evident in the brown bast syndrome. Formation of tyloses in latex vessels their ultimate lignification and the significance of these are considered in the paper. Although histological changes are evident in the laticiferous system and associated tissue it is shown that the earliest symptoms are evident in the laticifer and hence the causative mechanism should be sought in the physiology of the laticiferous system.
