Laticifers in Euphorbiaceae–a conspectus. Despite the multitude of references on laticifers in Euphorbiaceae, much of the work concentrated on economically important, and often highly specialized genera, particularly Euphorbia and Hevea, the evolution of the laticifer in the family is poorly understood. In this paper, laticifers, in a representative sample of genera of Euphorbiaceae, are investigated with respect to morphology and distribution. This information is supplemented with a review of existing literature. It seems probable that the articulated and non-articulated types are not as divergent as commonly supposed, since both may undergo intrusive growth, although more ontogenetic studies are needed to clarify the relationship between them.
