JATROPHA MACRANTHA MÜLL. ARG.

Stem cortex cells have druses, tannins and in lesser number mucilage cells. Wood is diffused fibrous. Axial matrix is formed by libriform fibers, gelatinous fibers, septate fibers, scanty vasicentric and apotracheal parenchyma, also vessels with scalariform and circular bordered pitting. (Fig. 2G, H). Ray system is uniseriate. Ray parenchyma cells become lignified when meet the vessels and sometimes when ray cells are not close to vessels. There is little functional phloem and much of collapsed phloem has parenchyma cells and scattered mucilage cells. Collapsed phloem is distorted due to the dilatation of the axial secondary phloem ray parenchyma. Pith was not fixed.
