[from old catalog]; Nitrogen. 476 Bulletin No. 179 [March, Two types of nodules have been recognized by Tschirch;i Lupinus (lupine) represents one type and Robina (locust) the other. As may be seen by reference to Plates I and II, they differ in morphological appearance. The Lupinus tj^pe involves a swelling of the central root cylinders themselves, while in the Robina type only the epidermal and the endodermal tissues seem to enlarge. According to Tschirch, the nodules of lupines alone are of the first type, while those of all other legumes belong to the second. The figures in Plate III are sufficient to illustrate the most com- mon shapes of the Robina type. The shape varies with the different species of legumes, and to a certain extent with the individuals on the same legume plant. In the experimental work reported in this publi- cation, over twenty thousand nodules were examined closely, and it was not uncommon to find on the same plant notable variations due to external obstructions to growth. Infection The artificial inoculation of a plant is easily accomplished by con- tact. If the epidermis of the root is wounded and the infecting or- ganism {B. radicicola) brought into contact with the wound, nodules.
