Abstract
The non-articulate, simple, feebly branched laticifers ofEuphorbia tirucalli, occurring in the stem and leaf, have been investigated. The young laticifers are multinucleate, thin-walled, and full of contents, while the older ones develop a secondary wall traversed by numerous, obliquely running pit-canals. A qualitative analysis of the latex shows presence of some carbohydrates, proteolytic enzymes, amylase, etc.
