The fine structure of trypanosomatids from the plants Euphorbia hyssopifolia, E. characias, E. pinea , and Manihot esculenta , cultivated under axenic conditions, was compared. All parasites had a structural organization characteristic of members of the Trypanosomatidae. The organization of the membranes of the endoplasmic reticulum (ER) varied according to the isolate. In Phytomonas francai (isolated from M. esculenta ), the ER cisternae form parallel rows. In Phytomonas sp. from E. characias , a para‐crystalline array of the ribosomes attached to the ER membranes was observed. The ER membranes found in Phytomonas sp. from E. pinea seemed to originate from the central portion of the protozoon, branching in all directions. The peroxisome‐like organelle (glycosome) found in Phytomonas sp. from E. hyssopifolia and E. characias occasionally showed an organized array. Taken together, the morphological observations make it possible to distinguish the four isolates of Phytomonas.
