Eight species of Euphorbia in the subgenus Chamaesyce were investigated anatomically from collections made in Kansas. The latex system is composed of branched nonarticulated laticiferous cells. These laticifers are distributed regularly or apparently at random through the cortex of root and stem depending upon the species. When the outer cortex is destroyed by periderm as in the root or the inner cortex by crushing as in the stem, there are still laticiferous cells apparent in these two organs. The most extensive branching network of laticifers is developed in the leaf. No anastomoses were found. The commonest latex system in the leaf was found to be the subepidermal system.
